Default At max freshwater operation doesn't discriminate good

I took my at Maxx out to an island last week and it doesn't seem to discriminate very good under water. Pull tabs rang up the same as nails is there a setting I'm overlooking? Also, anybody have problems with the coil plug unscrewing?

My ATP has a different VDI from dry to mud to water. I have to ground balance for each and it stabilizes but it's not usually the same on land as it is in water.

I do have to keep checking the coil plug but usually just at the start of an outing. I've never had problems with it if I did that.

Often times your sweep speed is slower in the water.
Sweep speed has a lot to do with how most machines behave
in regards to detection and discrimination.
