Best graph I have seen illustrating masking (XP DEUS REACTIVITY) March 25, 2012 06:20PM |
I was going through the manual and the reactivity drawing really grabbed my attention....We talk so much about the effect's of masking and I know alot of newcomer's have a hard time understanding what really happen's but this chart simplifies the effect's so easily...
I think you will find most detector's made in the past are on the 0-1.5 scale...in the last few year's FT has moved up to the 2 range ..
I think you E-trac sovereign explorer guys will find your reactivity to be in the 0-1 area .
The FT/Tek detector's like T2 and f-75 will be in the 2 to 2.5 range..
I have an XP GOLDMAXX Power and the DEUS manual states it's a 2 and it is a dead heat with a T-2...
The F-75 seems a hair faster than 2 but maybe 2.5 ...
A tejon would be around 1.5 or so would think..
So I think you can see where the ultra fast response could benefit...you will loose depth but gain separation...
Also the videos you see comparing the DEUS to a Etrac I notice the DEUS is on like 2 reactivity...to be more realistic on the test the DEUS needs to be turned down to 0 or 1 and the audio would clean up and id better on the deep target's..
That the beauty of the DEUS the abiltiy to mimic and compete with other machine's.
The DEUS will be the fastest maschine made in iron and can have depth in open area's...It will compete across the board if you adjust accordingly and know what the setting's can do..
This is the reason I see it as a VLf Multi machine replacer...

Keith --
Thanks for that. Usually, I run my Explorer just as you said, in terms of sensitivity -- as much as I can possibly take, until the falsing is too out-of-control. When soil is not saturated, I can usually tolerate sensitivity within a few points of maxed out with the large coil, and at or a notch below max with a small coil. But, I was just wondering if running that way IN THE TRASH is giving that "widening of the footprint" effect, which would seem to be dis-advantageous and counter-productive, if I am trying to maximize "separation." As you said, engineering design plays a huge part, and I just don't know, on the Explorer. My instinct, after using the machine for awhile now, would tell me that running something more "moderate" in terms of sensitivity would give a "smaller footprint," and thus might be better in the heavy trash, but you said you had the opposite experience, so maybe I'm off on this.
Yes, I hear you on the "zero" (normal response) and "0.5" (fast response) on an Explorer!
I realize that to some degree, the better option is to just switch machines to something more appropriate (in my case, taking the Gold Bug Pro out of the truck!) But, like you say, I have come to really like the Explorer audio...and it's hard for me to put it down and pick up a different unit.
I hadn't thought of the Joey coil. I have the X-5, but have yet to learn to utilize it to its fullest potential. At this point, the area I am WEAKEST in, in terms of detecting, is unmasking (hunting in dense trash). I have very little, if any, skill in this area, and it's time I learn it. While SOME of the "yet to be found" stuff in my area is deep, that's not the majority. In our dense clay, many targets stay fairly shallow, and thus have been found in the past by old-timers using even lower-end machines. Thus, more of the "yet to be found" goodies in my area are likely the ones that are hidden in trash, and to become a more succesful, and more well-rounded hunter, I need to begin learning these "unmasking" skills...
Thanks!
Steve

Keith...
I hear you on the GB Pro. I have been moving in this direction (learning the "unmasking" skills, using this unit instead of the Explorer), and when I hit the "right" site, I will do it. Problem is, as good as the Gold Bug Pro might handle this chore in NAIL-type trash, most of my sites aren't of this type. Finding those OLD sites where the primary trash type is iron (square) nails is tough here in "young" Oklahoma. However, I know of a couple back home in PA that I am going to try the Bug on, just as we have discussed. "Unmasking" amongst the modern pull tabs, screw caps, and can slaw is different...
Anyway, thanks so much for the detailed info...makes complete sense.
And, whether "uneekable" is a word or not, I got a good chuckle!

NASA-Tom.
Gotcha. I have one question, and one comment...
The question -- while your statement that strong "electro" and "magnetic" signals from a nail will still "trump," with respect to any nearby good targets, makes sense, I want to make sure I understand fully.
I think I am correct (please tell me if I'm not) in that if I make my machine "more sensitive," (higher sens.), the machine might then "report" the very weak signal from a nail which is sitting, say, 2" outside the edge of my coil, whereas if I lowered sensitivity sufficiently, I'd reach a point where the machine would not report this weak signal to me. Right so far? In my mind, I was thinking this would help in terms of masking. BUT, I think where my thinking was wrong, is that even though my machine may not REPORT that weak nail signal to me if I run lower sensitivity, as it otherwise would if I were running higher sensitivity, the issue is that whether it REPORTS the signal to me, OR NOT, the fact is that machine is still SENSING, and thus being influenced by, that iron target (thus, I'm not reducing the EFFECTS of iron, just reducing how often the machine REPORTS this iron, to me). Is this the reason why you can't "reduce masking" by reducing sensitivity?
The comment -- I think there is another advantage to the Explorer/E-Trac, beyond just depth. This may or may not be related to what you referred to as the "more resonant to higher conductors" thing, but I know I dig WAY less modern trash with an Explorer, than most other units. For example, usually I hunt either jewelry (rarely) with my Gold Bug Pro, or old coins, with my Explorer. Almost never do I "clad hunt." Just to do something different, though, I grabbed the Gold Bug Pro the other day and went "clad hunting" for a couple of hours. While this machine does a good job in this regard -- cherry-picking clad (if you so wish to do it) can be easily accomplished by cranking up the disc, I quickly remembered one huge limitation -- and that is that this machine LOVES modern beer-bottle screw caps! A Bud Light cap, for instance, is a solid quarter hit on this machine. I could find no definitive "trick" to eliminate them, and I tried several. The funny thing is, I have NOT ONCE, in the last 6 months, dug even ONE of these, with my Explorer. While a flattened cap from a wine bottle (the much larger aluminum screw caps) will sometimes fool me, I NEVER dig a beer bottle cap. The difference was drastic, and shocking! Point being, in old coin turf-hunting scenarios in trashy public spots, this is ANOTHER place the FBS units excel. You can hunt FASTER, with less junk digging, and thus more focus on FINDING SILVER! I don't know if that's more of a "resonant to higher conductors" thing, or if it's superior ID ability due to the multi-frequencies, or what, but it's real, and significant...
Thanks,
Steve
