Monte has gone over to the darkside! Multi-IQ!

I know the Nokta Fors CoRe is a proven performer in the nails. Therefore, assuming similar software was used in the Nokta Impact, I drug it out the other day to test it on nails. Using the 7-1/2"X4" DD coil, it passes all of the tests except the parallel nail test. (see attached pic. for detail) (The stack of silver was not tested, since I don't have one....yet

I believe it failed for the same reason the EQ800 fails - the DD coil. When passing vertically over this arrangement, the blade like field emanating from a DD coil simply picks up too much iron to respond to the coin. Its pattern would encompass BOTH nails in this vertical pass. Works fine, swung in a horizontal side-to-side direction.

So I put the 7" concentric coil on the Impact. Passes the test! The more pointed "cone" field shape can get in between the nails to see the coin.

The EQs as of this press time do not have a concentric coil available. Too bad. This rules out the EQs for ghost towns, for me. I still think it may be the best park/school/grass detector out there. Given a small concentric coil, the EQs would pass the test, I'm certain. On the stack of silver test, the EQ sounds off as "can slaw", or like a bottle cap. Not a problem - switch to 10KHz and it reads good - a known trick. I wouldn't expect to run across a lot of silver stacks anyway
