Excal Question Losing Thresh Hold

[Acornhead]

I've hit a local beach on Lake Erie, and when I hunt there, the Excal 2 will null out, in other words they'll be no thresh hold for most of the time as I'm searching. If I stop the thresh hold comes back. I do pick up targets, but I don't remember the thresh hold doing that at this site before. I have the Sens at 5-6 and discrimination at 1. Does this mean there's lots of iron at the site? Am I missing targets? Hopefully the machine is still working right. This is obviously fresh water. Des in Buffalo

The next time this happens, drop a target on the ground and see if the threshold comes back ( target signal ) then go's blank again as you start your scanning again. It sounds like there is a lot of iron in the ground in that area and it is
being canceled out ( as it should be ). Try the machine in a different area with the same setting and compare results ( your yard or other should do for this ). If it works at home or other site then it's working like it is suppose to.

Thanks so much! Des

With your sensitivity settings you would do as well hunting in auto. If its nulling sound like iron..... does your pitch hold change tones? Switch over to PP and run across the area that should tell you.

Just too see, take 15 minutes and run in PP with disc at 3 to 5 and or another 15 with sens as low as it takes to run right. You have a fair depth at even 1 and it will work better than constantly nulling. The Excal is so easy to change settings on yet I seldom hear of guys experimenting away from Disc 1 (pinned) and sens 5 (noon). If it isn't working, shift gears for a few minutes. WTH?

Des,I would try the Excal in another area to see if there is a improvement.

Good advice.
