thanks max!!! i hope it is ok to post someone elses g2 review here as well ? ..............
"This Teknetics Forum is a great place to hang out and learn about all of their models and how to work them to our benefit for the types of detecting we do. That's good.
The greatest number of metal detecting hobbyists fall into the range of 'average' or 'typical' or 'traditional' coin hunters, so this Teknetics Forum will certainly help them because most coin hunting is done using the motion Discriminate mode and folks here are helpful. That is good.
Certainly a fair share of the very avid detectorists who spend ample time in non-urban environments seeking left-overs from old military battles or ghosted town sites or other such sites are considered devoted relic hunters. Most tend to use very low Discriminate settings, and often do not pay as much attention to their visual Target ID, but they post their finds and stories about their settings and success. That is good.
There is one thing we seldom hear discussed much on forums like this, and another topic that seems to be over-touted, in my opinion. We don't hear too much talk about searching in the All Metal mode, which is something associated with gold nugget hunters, but also a great method to search for many serious detectorists. Usually relic hunters, but occasionally coin hunters, can use this method of search. That's not a frequent subject on the forum. There is one thing that seems to pop up all too often, either in great claims or a topic of discussion, and that is depth. Depth, depth depth!
Sure, there are times when I would like to get a little better depth at some sites, but all too often the cries for 'more depth' seem to come from people who are looking for good targets located under shallower and undesired trash. The target masking calls for the trash to be removed from the site to better expose desired targets because trying to get 'depth' under typical junk like nails or bottle caps or screw caps is not going to happen. Also, too many situations are where there just aren't likely to be any deeper coins at a site. They are cleans of shallow rubbish, and most coins have already been found at very popular detected site. Lets face it, those of us who got an early start in the sport were rewarded for all the time we put in thinning out the silver and other older coins. In most popular sites, which have been cleaned of masking junk, there usually isn't any benefit for 'depth' because there's nothing there.
I mention these things because I have a solid opinion about them based on the fact that I am in my 46th year of detecting, I am a very active, avid detectorist, I have enjoyed great success in many US states, but mainly 'Out West', and I like to have more than one detector n my personal arsenal, with a good search coil selection, so that I am best fitted for a number of different challenges I face. Urban 'Coin hunting' or rural 'Relic Hunting,' or visiting Gold Nugget bearing sites in mountains or desert, calls for a mixed set of needs and wants. I was ready to evaluate the new G2 because I knew there was a potential that it might be what I was looking for.
I got a prototype G2 and I'm now working on the 3rd 9-volt battery in just 16 days. Knowing how well these light and handy Teknetics models can operate on a single 9-volt, you can imagine the amount of time I put in with long days of hunting, occasionally starting early or working just into the dark at times. So, there's the time I have devoted so far, but what types of sites have I hunted?
I live on the west end of the Portland, Oregon metro area and there are three old home sites I have been working with my Omega, mainly, and also the T2. Two are vacant lots where the old homes were razed long ago, and the third site has a 1900 home on it that will be restored, but the new owner has been clearing the double lot in preparation of moving the house to the other side then restoring it. The trouble with all three of these sites is that there is a lot of shallow junk. Not everywhere, but in some sections it is terrible. So I have those three old home sites to hunt.
To my list of favorite places where I still pull silver and other early version coins, like Buffalo and 'V' nickels and Indian Heads cents to compliment the silver, there are four early-use city parks in Portland, one about 289± acres, that continue to kick out desired coins. In the last dozen years I am still pulling the occasional Morgan dollar and periodic Seated Liberty, plus silver and others from the 1890 to 1945 period. Most good stuff doesn't come for the open areas that are easily (and frequently) searched, but from out of the way or fringe areas that have been overgrown for many decades. I always keep an eye open for any sidewalk or other renovation and have lucked upon two or three such sites, one with a dense scattering of iron nails.
In recent years I have used many competitive models, and with good success, such as the White's MXT and XL Pro and XLT and Classic IDX Pro's. A Garrett GTAx 1250 and GTP 1350, Minelab X-Terra 70 and two Explorers, Fisher Gold Bug SE, and Tesoro Bandido, Bandido II µMAX, and Vaquero, plus a Diablo µMAX which was mainly used on our nasty big river beaches. These have been used in these and other popularly worked places. There is no such thing as a 'perfect' detector, especially if you hunt a wide variety of sites, so I like to keep a few models on hand in my personal detector battery to be prepared.
I wasn't going to work the G2 alone without comparison, or only with the stock coil. To me, that would be too slanted and biased, and besides, I wanted to know just how good it was, or wasn't, to see if it might work for me full-time. So, I set out to work it hard and burn through batteries taking along my T2 w/11" BiAxial coil, my Omega with the stock elliptical 10" concentric coil and round 5" DD mounted on a spare lower rod, as well as borrowing the lower rod and round 8" concentric coil off the Delta. I also used one White's model and one Tesoro just for little close-quarters testing and such.
I am certain, at this point, that the first question you might have is why I took the two concentric coils when we have read that the G2 and Gold Bugs were designed to use the Double-D designs. I've read those comments in advance as well, but I like to know what works and doesn't work for me, and one way to find out is prove or disprove their strengths. For those who dont know me or follow much of what I post through the years, I am quite partial to smaller-than-stock coils, most of the time, and I also appreciate a light weight detector, and coils that are not nose-heavy by design. So, for my initial start-up, I decided to work the G2 with the stock 11" BiAxial Double-D coil, then swap coils at different sites to see which was the best 'fit' for me and the applications I might have for it.
Search Coil Performance on the G2: I usually don't like to use the word 'perfect' in these cases but that is just the word to describe how the Teknetics G2 performed with every search coil. Double-D or Concentric, this detector worked quite well. Ground Balancing in All Metal was no problem with any coil. Ground Grab and manual GB, all worked perfect in a variety of sites. All of them, by the way, produce 1, 2, or 3 Fe3O4 bars on the Omega and also on other models.
VDI Read-Out for US Coins: Once again, I was beyond impressed, and I am including ALL of the 4 search coils available! In the motion Discriminate mode I used everything I had available, both in an "air test" or sat on the ground, or located in a search as was naturally buried. These included the US silver 3¢, 5¢, Indian Head and Zinc and good Copper 1¢, clad and silver 10¢, clad and silver 25¢, clad and silver 50¢, and the modern $1 as well as a silver $1. Not only did they lock and register well if within the G2's detection range, but the VDI number 'lock-on' was, in my opinion, more tight and accurate than my personal Omega was.
Variably Adjusted Range of Accepted Tone and/or Rejection: This one isn't all that easy to explain to the newcomer, and even I took a bit to get used to what I did and didn't like about a setting. In short it works kind of like this. The upper display spans a range of 0-to-100 from left to right. The '40' reading is larger than the other 10-step read-outs for a good reason. Generally, targets that respond in the 0 to 40 range are Iron (Ferrous) metals, and those that have a VDI above '40' are Non-Iron (Non-ferrous) targets. That part is simple.
When you turn the G2 On in the Discriminate mode, ALL of the upper range is briefly displayed with a dark black band. Everything , and that means all targets, Iron and Non-Iron, will respond and produce a higher VCO audio response. There is no rejection and only a dedicated great audio hit.
If you increase the Discrimination level to a setting of '80,' then everything that would normally produce a VDI response less than that is rejected. No sound at all, just rejected, and everything that has an '80' or higher VDI will also fall in a black colored zone you see during that Disc. setting, and will produce the Higher tone VCO audio response. So, you can accept EVERYTHING or accept ONLY HIGH-READING VDI's from '80' up, and there will only be one single audio response which is the higher tone VCO audio.
No we can get into the variable Discriminate setting you choose between those two settings of '0' and '80.' This will allow the user to have some adjustment control over a lower Iron Audio Tone and the higher VCO audio response, and after a setting of '40' in will start to include some target rejection range as well. I enjoy this adjustment function and learned how to tailor it for the particular sites I was hunting. Often I search where everything is accepted (all metals) and with the Omega or Gamma or T2 I can simply opt for a d2 or 2+ Audio Tone and it will give a lower bass tone on Iron targets. The G2 lets me adjust that a little differently as follows:
With a Discriminate setting of '0', EVERY target gives the VCO audio response.
With a Discriminate setting up to '40', everything at/below that setting is displayed with a grey shaded zone, and above with the black colored zone. Thus Iron responds with a lower audio tone and VDI readings above with the VCO audio.
Let's say I want to hear all targets present, both Iron and Non-Iron, but want to audibly hear nails and lower-reading targets only with a lower audio response. Perhaps those targets at a site produce a VDI read-out of maybe 21-23. If I increase the Discriminate setting to about 24-25, then all lower-reading VDI's will produce the lower audio tone, and targets with a VDI above '25' will have the desired VCO audio response. Yes, that means you can adjust the 'tone-break' so that some lower-reading Iron gives the low-tone audio, but some Iron (which you might want to find) and Non-Iron will report with the VCO high tone audio. Note that there is no target rejection as long as the Discriminate level is set at '40' or lower. There is only a division between the lower audio response and the higher VCO audio.
An abundance of lower-conductive trash at a site might push you to the point of target rejection. That, too, is easily adjusted with the - and + key-pads. If I have a bunch of those 21-23 VDI reading targets present and just don't want to hear them, I can use the + key-pad and increase the Discriminate level while viewing the VDI scale above. If I take it up to the point where the left side of the shaded grey scale is at about '24,' then all lower VDI reading targets are rejected.
Take note than when you have a Discriminate setting of '40' all targets above that are in a black band (higher VCO audio range) and everything below '40 is grey shaded, and there is no rejection. This will display the largest amount of grey-shade area, which would include all Iron. As the Discriminate level is increased above the '40' setting, all targets above that will produce the VCO audio, and you will start to see the shaded grey band start to shrink proportionate to the increased Disc. setting. Also, one you adjust above '40,' the lowest VDI numbers starting at '0' will progressively be discriminated or rejected.
Following this Disc. adjustment, you might increase to a Discriminate setting of '54' and almost all US 5¢ coins (VDI ± 57) will produce a VCO high tone, targets below '54', including some Non-Ferrous targets will fall into the low-tone audio range (shaded grey scale) and lower-reading targets will be rejected.
As the Discriminate setting gets closer to only accepting the high-conductive US coins, the shaded grey scale is quickly diminishing so that at a setting of '80,' as mentioned earlier, you have the greatest amount of rejection, NO shaded zone with a lower audio, and ONLY the higher VCO audio on accepted high-conductive targets.
If all this confused you, that's good because it means you've tried to make sense of what I am explaining, and maybe realizing that the Discriminate adjustment and the potential for only a VCO audio or a low-tone and VCO audio or target rejection and low-tone audio and higher VCO audio as well as a lot of rejection and only VCO audio, are able to be set up as the operator desires. With practice, and I mean worming a lot of sites, several quite trashy, and burning through 2+ batteries, I was able to determine that the flexibility suits me quite nicely for many sites I like to hunt. Therefore, only you, the operator, will know if it's something you like or not once you have ample experience with it.
All Metal Mode's Threshold Setting: This is an excellent adjustment function that allows smooth fine-tuning. It spans a range from -40 to +40 (displayed in the lower right corner), and depending upon the EMI at a few sites or the nearby traffic and noise, I usually used a Threshold setting anywhere from +2 to +8 or +10, and that was with my Killer B Wasp or SunRay Pro Gold headphones.
Uncluttered Control Panel: Part of the beauty of the Teknetics G2 is the simple control panel that features two (2) knobs and three (3) touch pads. That's it! The ranges of use of these controls are as follows:
On the left side is the Power/Gain control. This turns the G2 On and Off. In the Discriminate mode is functions as the Sensitivity control with a range from 1 to 100. If you're in the All Metal mode, it serves as the Gain control and ranging from 5 to 100 in steps of 5.
On the right side of the display is the Mode selector which put you in the Discriminate mode when turned fully counter-clockwise to the clicked position. Once you click out of that and turn the control clockwise, you are in the All Metal mode and adjusting the Threshold level from -40 to +40.
Between the knobs are three touch pads. One in the top-center is used to activate the automated Ground Grab when you are in the All Metal mode and bob the search coil. If you are searching in the Discriminate mode, that touch-pad then serves as the Pinpoint activate button.
All that remains are two arrow-shaped touch-pads. The one pointing left is marked with a - sign, and the arrow touch-pad pointing to the right has a + mark. In the Discriminate mode they are used to adjust the Discriminate range from 0 to 80, and when in the All Metal mode they are the manual GB controls that span a range from 1 to 99.9
Basic Informative Display: As simple as the control panel is, the display is equally pleasant and easy-to-see. There is the 0 to 100 arc across the top of the display. In the Disc. mode youll have a momentary black or shaded range displayed based on the Discriminate level adjustment. In both the All Metal and Discriminate mode, upon a targets detection, you will see three (3) segments illuminate over the arc to correlate the VDI read-out.
In the center of the display will be a larger, 2-digit number. In the Discriminate mode, this will be the target VDI read-out. In the All metal mode, it is a display of the Ground Phase based ion info processed during the search coil sweep. In All Metal you can glance at this Ground Phase reading and compare it with your Ground Balance setting (lower right) and if they are notably different, it alerts you to check and adjust the Ground Balance.
On the left side of the display of seven (7) bars, narrow at the bottom and wider at the top. These function in the Discriminate mode as an indication of the Signal Strength. In the All Metal mode they display the amount of Fe3O4 (iron oxide) in the ground and is a measurement of the amount of mineralization in the ground.
On the right side of the display is a numeric read-out for the Discriminate mode that shows the discriminate level in a 2-digit format. In the All Metal mode it shows the Ground Balance setting in a 3-digit display. The default Ground Balance setting is 82.9 and while the Ground Phase is displayed in the center as a 2-digit number, the actual Ground Balance is 3 numbers (with the decimal point).
General Overview of the G2 Performance for Me: The Teknetics G2, like the Fisher Gold Bug, is really directed toward the gold nugget hunter or anyone who likes to hunt in the threshold-based All Metal mode. I like that because I often do, and the detector is light, handy, easy to adjust, and is an excellent performing unit in this mode. Best mode for depth of detection, as it usually is with most detectors.
As a higher frequency detector (19 kHz) I didn't expect it to be the deepest-seeking mode in the Discriminate mode, or show the best performance with higher-conductive targets. Those expectations held true. Overall, I could get a little better depth, especially on silver coins and big copper coins/target using the T2 or Omega or Gamma. The G2, again as expected, did perform better on the lower-conductive coins, such as the US 5¢, and the women's gold ring I located.
Use of the G2 will be different from many detectors that the 'average' coin hunter or relic hunter uses due in part to the detection based on the frequency and target make-up, but also because the operating 'process' Teknetics used in this mode is different. It does a better job on depth and detecting in 'average conditions' with a somewhat brisker sweep speed. Faster than my T2 or Omega or Gamma, if I want better response on mid-range top higher-conductive targets, to be sure.
Straight up, I am mainly out hunting coins, trade tokens, jewelry and other small artifacts. A lot of my 'coin hunting' is urban based because I am stuck here most of the time. My heartfelt desire, however, is to get out-of-town to any older site. In short, I prefer to take a 'relic hunter' approach to detecting. I don't like much discrimination. I recover a lot of targets, both good and bad. While I prefer to research and seek out older-use sites, I am still on whatever path leads me to older coins and good trade tokens. Naturally, I will take all the good silver and gold jewelry I can find.
Most of my success through the years has come from using lower frequency detectors, and I have been well rewarded. This is one reason why I have found the Teknetics Omega (and Gamma and Delta) to satisfy me a great deal. That 7.8 kHz operation signals well over a broad range of conductivities. I have used some mid-to-higher frequency models for other manufacturers and in the case of the White's MXT and M6 I was successful, and that's sort of what drove me to the Teknetics T2. While I like the T2 I prefer the Target ID and some performance of the Omega. I'll tinker with a Fisher F75 this winter and consider adding it to my detector battery, probably replacing the T2, if it does better for my coin hunting needs.
So, with all this satisfaction, why would I even be remotely interested in the new Teknetics G2? Simple. I do a little nugget hunting when possible, and I like to hunt some sites in All Metal, only. To compliment that I was interested in the G2 performance with the faster processing time when using a smaller coil in some of the really junky sites I hit.
At the various sites I hunted, several were a junk challenge, to be sure. I usually use my 5" DD coil on the Omega so I wanted to put it to work on the G2. The stock G2 coil is the 11" BiAxial DD. I like that coil mainly for site coverage, and in low-target areas it was a pleasure to use. I have my spare coils on lower rods so changes in the field are quick. Using the G2 a lot left me more challenges that before as to which coil is the best to keep mounted most of the time, and for me that was sort of easy. I do like the 11" DD coil, but I don't get into that many low-target sites with a lot of ground to cover. Instead, most places have ample targets, including trash, and it takes more patience to work them efficiently.
So, I am now going to set the 11" coil and rod aside but ready when needed. I have been impressed with the 10' elliptical concentric coil on the Omega, but was pleasantly surprised how well the G2 and I got along in moderate target level sites. I almost decided to keep the 5" DD on my Omega as I had for the entire month of September and use the sub-10" elliptical concentric coil o the G2. That was until I swapped coils at the trashy old home sites with some debris at one of them. The 5" DD coil combined with the efficient process of the G2 and the very quick-response and fast recovery time let that combination pull coins and other small-sized artifacts from some real, challenges.
Glitches: Nothing is perfect but there wasn't too much to fault with the G2. It is a higher frequency unit, is was designed primarily to be used in the All Metal mode for gold nugget hunting, it features a Discriminate mode for some measure of versatility. For all that they have given us a very nice detector. It is versatile, but when hunting in the Discriminate mode it will do better on lower conductive targets. For those who want a very good All Metal method of search, they have one of the best they could imagine in the G2. To acquire the best depth possible, it does call for a little faster sweep speed in the Discriminate mode, but it is not a 'depth monster,' if that's what you're shopping for.
For what it is, it works. For me and my hunting needs, I think the G2 will help me out the most with the 5" DD coil because I used that combination at two old house sites I had been hunting for a month-and-a-half but they were trashy, and I had used the 5" coil all September on the Omega, too. Due to the trash level I knew I wasn't going to achieve any depth, but I wanted to deal with the target masking. I did well with the 5" and Omega, but I did double-the-finds using the 5" DD coil on the new G2!
Other than older sites I also used the G2 with various coils for some day-to-day coin hunting just to check the response on lot of foil and US 5¢ coins, only to find the very nice 14k women's ring with 10 diamonds in a channel setting. No, not huge stones, but I enjoyed the find with a new detector, and close to metal structures that others had hunted around recently. I'll mount the stock 11" DD coil when I have a lot of open area to cover, such as a beach or when looking up and down a draw for gold nuggets. Of all four search coils, my favorites are still the 5" DD and the 10" elliptical concentric for the sites I hunt, and that proved to be true with the G2 as well as the Omega for me. But I'll leave the stock 10" concentric on the Omega, the 5" on the G2, have the 11' DD mounted on a lower rod and ready-to-use when I feel the time is right.
As with any make and model it is not for someone else to say a particular unit is just what YOU need, but I can tell you that it is a unit that I need. Then I'll add that I think YOU might want to check one out. Give it time and see what appeals to you. I did, in the end, have one problem that I just have to live with and that is Coin Depth read-out. The VDI readings on my G2 prototype were spot on. All coils, perfect. Everything was near perfect as I anticipated for what we have, but the Coin Depth reading was usually off a lot in the Discriminate mode with it registering '0' to 1" but I had to recover the coin or similar-size junk from a depth of 3"-4 ". That was with all coils and in many situations. The VCO audio peaks very quickly and you hear a pronounced audio response, then maybe get a shallow-reading coin indication, but have to go a little deeper to get it. So, with a Coin Depth that isn't perfect all the time, I figured that wasn't such a big deal to me.
If you own a Delta or Gamma or Omega, the new G2 ought to be a consideration to compliment your arsenal. It gives you different TID audio information at a higher frequency, yet shares all the same search coils. Its a good new model for me, and now that this project is completed, the folks at Teknetics (FTP) can start concentrating on other models improvement or different new model projects. It seems they enjoy doing that".
