F75.. has anyone tried hunting with..

[willy]

.. the trigger pushed forwards? should be like searching with ground tracking. Too bad they didn't see fit to have ground tracking on the F75, it would be a benefit when hunting over certain types of ground. ..Willy.

Did a bit of playing around with the F75. First was in disc. mode, second in motion AM. Basically, with the trigger pushed forwards, it was like being in motion AM mode, but with no TID (just ground phase). AFAIK, it was tracking the ground the whole time, and probably pretty quickly too. Had some targets and they sounded off nicely and didn't get tracked out, though that might happen with a really small target. Interesting thing was that a ferrous disc I threw down could be disc'ed out at a very low setting with the F75 and the M6 just didn't want to let loose of it; really had to crank up the disc. This was also with the stock concentric coil on the M6 vs the stock DD on the F75. Strange since DD coils are said to have more problems knocking out iron. ..Willy.

Willy, yes it does track and does so quickly. It does not track out my 2 grain piece, and I don't see any difference from hunting within the regular all-metal motion mode in terms of sensitivity/depth. Soon as I saw your post I grabbed the 75 and headed down to the basement to run a test. Mind you I couldn't bury anything, but just put a penny diameter size chunk of magnetite (GB @ 89), and the nugget separately on the carpet. The ground beneath the carpet/concrete floor reads GB @ 87, magnetite @ 0.1%.

Next I manually set the GB to 50 and within two sweeps on the floor it was balanced. Repeat on the magnetite = same results. Over the nugget, nothing to suggest even a hint of tracking out. Finally placed nugget beneath the balanced magnetite = a dandy signal.

Now it seems the interesting thing will be to figure a way to be able modify the switch to "lock" it into the forward position when needed for those tough variable areas. WTG Willy.

was it something in between the 50 and 87? If it tracked accurately to the magnetite, then that implies the "bob method" isn't required for fast grab. I've personally never tried to check this out but just assumed that the bobbing motion was required to get a correct GB.

Hi Brad,

Yes, within two sweeps it was balanced to "87" for the floor. In the example I used above, if you "bobbed" the detector coil over the magnetite just once...it was immediately balanced to the "89" setting. Regardless of whether it was the floor or the magnetite sample, sweeping the coil back and forth just once (which is actually crossing the target twice) balanced the detector such that there was no signal response. Perfectly balanced.

Jim.
