Re: Sometimes it is great to be wrong!! - 16 years ago
Hmm...how about a box of Partagas PS2's instead of a ticket and kennel boarding :-) I'm going to Corning, NY in the middle of October, I have 3-4 or so detecting days planned into the trip (planning to look for Colonial cellar holes).

Re: Sometimes it is great to be wrong!! - 16 years ago
Is that Wiffleboy SR or JR ? Nice finding Brad. It sounds like Fisher should skip the 5" DD included in the package and include one of those fancy extra heavy duty shovels instead :-) I'm still skeptical of the LTDs in my soil, however I am VERY hopeful.by Cal_cobra - Thomas Dankowski Metal Detecting Forum

Re: CZ Iron Disc Mod ? - 16 years ago
This iron disc mod has me interested, it would be a super simple mod. A small switch could easily be mounted at the rear of the case. When the iron disc mod poster states that small iron would give a low tone (normal iron grunt tone), but larger iron would produce a higher tone, do you believe this would be the foil tone? If I understand his mod correctly it would effectively be like adding aby Cal_cobra - Thomas Dankowski Metal Detecting Forum
Re: CZ70 Positive Groundbalance vs Sens 6 ? - 16 years ago
Tom I tried to set the sensitivity at 6 at the site I hunted this afternoon, and although it was better then the site I previously tried 6 at, it was still falsing a bit more then I'd like. It was tolerable, but it reminds me of my F70 :-) Although I didn't make any stellar numismatic finds, I did dig the deepest coin I believe I've yet to dig.

CZ Iron Disc Mod ? - 16 years ago
I was reading all the old findmall forum CZ70 posts, and ran across a post whereas a gentlemen claims that by adding a 0.01µF cap between the white lead on the RX side of the coil and ground (he has a switch to switch it on/off), that he gets better iron disc results making the CZ machines great relic hunters.

Re: CZ70 Positive Groundbalance vs Sens 6 ? - 16 years ago
Thanks Tom. The park I'm going to tomorrow is the only place I've ever hunted that I've been able to max the sensitivity on threshold settings on both my C$ and my F70, so I suspect the CZ70 should perform very well here, and may well run well with the sens at 6 to get those extra deep coins.by Cal_cobra - Thomas Dankowski Metal Detecting Forum
Re: Save your pennies boys. - 16 years ago
IF FT doesn't address the EMI issues on the T2 LTD and F75 LTD then these new machines will be a waste of money for most areas I hunt. I assume they use the same coils as their T2 & F75 predecessors?

CZ70 Positive Groundbalance vs Sens 6 ? - 16 years ago
I found this post on a CZ Tips page, and although he doesn't state the benefit of using a positive GB, I assume it's increased depth. I wonder if using a positive GB will add falsing, and if so, if you'd achieve the same depth increase as using a sens of 6 (assuming you have a CZ70 that falses when set above 4) ? I've also been told (although the manual doesn't indiby Cal_cobra - Thomas Dankowski Metal Detecting Forum

Re: How do you set up the F70? - 16 years ago
The F70 is basically setup the same as the F75, except you have threshold in disc mode. Typically I find that setting the threshold at -9 helps to knock out tiny pieces of junk, as well as help stabilize the machine, and I tend to leave it there. F70 SL mode is the same as JE mode on the F75, DE mode is the same on both. I also run my disc at 6, nothing notched, and run the sens as high as I cby Cal_cobra - Thomas Dankowski Metal Detecting Forum
Re: CZ-70 Pro Delivers !! - 16 years ago
The F70/F75 are great machines, but I'm tired of being handicapped by EMI and mineralization when using them. The CZ is handling both with ease. It's not as fast, BUT if you want the deep stuff in parks you have to slow down no matter what machine your using, I'm willing to sacrifice a little speed for depth and better targets.

Re: CZ-70 Pro Delivers !! - 16 years ago
Thanks Tom. I left the sensitivity at 4 and was running the 10.5" coil (I love that coil!!!). I'll try setting the sensitivity at 6 tomorrow to see how she runs. That park dates back to the mid 1800's, maybe I can squeeze an extra couple of inches if it'll run with the sens at 6 and pick up some pre-1900's coins ? The CZ70 ran real well, I believe the multifreqby Cal_cobra - Thomas Dankowski Metal Detecting Forum

Lance thanks for the lead, if the museum doesn't pan out, I'll check them out. If I can find this old fairground I may have a shot at an unhunted site as so far nobody I've spoken to up there that's into history seems to know much if anything about it.

Test Garden Recommendation ???? - 16 years ago
I never seem to get the depth out of my machines I hear others report, as I seem to be limited to about 6" on coins (not including silver dollars and halfs), and have machines that I know should have a LOT more horsepower (C$, F5, F70, Tek Omega, Edge, etc). I figure a test garden is the only way to really test these machines out in a controlled test environment to learn what their really cby Cal_cobra - Thomas Dankowski Metal Detecting Forum

Re: F70 vs F75 Iron Handling ? - 16 years ago
Tom this is a good discussion, some great info here and food for thought. I knew the audio and TID were independent, but adding the disc behavior into the equation really emphasizes the importance of using the monotone setting for thick iron hunting, I'm looking forward to trying this out.

Re: F70 vs F75 Iron Handling ? - 16 years ago
Hi Tom, Thanks for your reply. I figured the discrimination would work as expected (silencing targets lower than your disc setting), but wasn't sure about the less than 15 'disc to tone reprogramming' when using multitones. It's good to know the F70 is the same as the F75 in this regard, as I was under the impression that a multitone option didn't change anything behiby Cal_cobra - Thomas Dankowski Metal Detecting Forum

F70 vs F75 Iron Handling ? - 16 years ago
Tom I read your article in the most recent Fisher World Treasure Newsletter on "F-75 Peak Performance." I was trying to equate the information to the F70. I've always (and perhaps incorrectly so) thought of the F70 as a F75 with less options, and for the most part assumed that coil for coil (say 11" DD for instance) both machines to be fairly equal in performance (depth ,by Cal_cobra - Thomas Dankowski Metal Detecting Forum

Help finding old topo maps - 16 years ago
I know some people are able to get to the old topo maps to find old places to hunt.
