lowering sinsitivity helps

[mikeh]

my son helped me lower the sinsitivity to 10 and I fond a dime and three pinnies thats great. thank you so much for your help and we can ajust from there.

then I drop it down to around 10-15 which works great. Also. I notice while hunting at the beach, the DD coil will false more then the 8" concentric coil. I tried both & the Concentric 8"er is the way to go at least for me anyway.

That's funny, because I never had any problem running mine at 18 in the wet sand and maybe 16 or 17 in the shallow water with minimal falsing. Even with the 12.5" coil I could run 17 or 18 all day and get killer depth too. Must be the different locale.

Hi Mike,
I am not sure why the DD coil would false MORE than the concentric coil except the smaller coverage. Usually people recommend a DD coil for when the concentric coils are falsing as the DDs see a smaller section of the sand. Could it be that you have some debris/saltwater inside your DD coil cover? Or if your sand has a high amount of magnetic iron so it is not the DD or concentric but the smaller coil coverage that is helping? But IMO if your Fisher doesn't false, I don't think the Quattro would.
I have this really bad black sand beach which used to be a channel connecting a volcano island to the sea and a CZ5 & PI unit would not stop falsing on every sweep. A ML Sov was able to hunt it but had to sweep much slower and it worked only for the first four inches. The best thing I did was to look for another beach! I've not tried the Quattro there yet but hope to do that this summer.

but not with the 8" coil. To me, the 8" coil runs smoother with less falsing with higher sensitivity.
