How would you like too get another couple inches of depth out of that new Technetics T2 or Fisher F-75 you just bought. Myself and Mike Scott from Outdoor Outfitters stumbled onto something that will get you that extra depth.
As I said in last nights message Mike let me use his Fisher F-75 the second and third day of the North South Hunt in Virginia. When we went to pick up the machine he was telling me that something fishy was going on with all the F-75's. It seems that the coin hunters that had bought F-75's were complaining that it was getting a lot of electrical interference. Thinking about it Mike had figured out that most coin hunters have several things in common. Number one they typically hunt in urban sites. Parks, schoools and the like.
Being that those sites are normally high trash areas...they also use a high amount of discrimination. If they hear static they figure it is electrical interference as that is also normal in downtown situations.
Keeping those things in mind..Mike and I started testing the F-75. What we discovered is that as you raise the discrimination past twenty on the F-75 you pick up a lot of depth. Let me say that one more time. "On the Fisher F-75 you will increase your depth if you raise your discrimination above 20".
Now we had the reason that the coin hunters were the ones complaining about electrical interference. What was actually happening was that they were increasing the sensitivity when they raised the discrimination setting past twenty..!!!!!
Here is how to prove it to yourself. Take your Fisher F-75 outside away from all electrical interference. Especially away from any flourescent lights. Now set the detector up with the sensitivity at 95 or as high as you can get it and still be stable. Set your dicrimination at 10. Get a coin. It doesn't matter which coin it is. Now test the detector and mark the spot where you get a good repeatable signal.
Once you have done that test...now adjust the dicrimination up to 25 and recheck the coin. At this point you will want to say something like "Holy $#!+. It is unreal.!!!! I am seeing about 2 inch plus increase in depth on my detector.
No detector has ever done that before that I am aware of. The Fisher F-75 has an automatic increase in depth as you raise the dicrimination past twenty.
Once we discovered that we also tested the Technetics T-2. Try it for yourself. Since the T2 has a wider range of iron you will note the increase at 50 for the new machines and at 40 on the first T-2 machines.
Mike did contact First Texas for an explanation and their response was "No comment". We have seen it for ourselves. Now go try it with your machine and let us know if you see that same thing happening.
