ground balancing out rocks

[dmnz]

Hi Guys

for water hunting where hot rocks are around (saltwater) would you suggest resetting the ATX to defaults - finding a hot rock - taking it out of the water onto the sand - ground balancing out the rock - then back in the water detecting?

I have found that ground balancing, in the water, over a hot rock is problematic?

Cheers

I have dug so few that are small enough to get into my scoop, I just live with the ones I do dig.
They keep me alert and give me something to do when any signal is welcome. Like a few days
ago, 3 hours and only 4 targets: 3 coins and one packaged fishing rig. I have not been to the one
beach which I can hardly swing without hitting a HOT ROCK, I will have to try the ATX there this winter
when the sand moves one, if it ever does. I'll let you know when I try it. I am interested in any other
ATX owners experience over the hot rock. I have seen the Garrett videos, just have not had a
big enough problem to re-tune over one. Thanks for asking the question, maybe we all will learn something.

We have a lot of hot rocks here - ranging in size from a golf ball to bowling ball....and they sound pretty good on the atx - I was interested to grab a few and find someone with a SDC2300 to see what that does. I know the dual field loves them also!

How is ground balancing in the water over a hot rock problematic?

 

[dmnz]

does it not kill depth in a MAJOR way for you? maybe it was just my experience ?

Ground balance is a trade off. If you do not need ground balancing you should not use a ground balancing PI. A Surf Dual will do the trick. At a minimum you should run ATX in rebooted non-ground balance to get best depth.

You apply as much ground balance as you need to overcome false signals from ground, salt water, or rocks. The more ground balancing you apply, the more depth am the lost but the less false signaling you will get. You get to decide which is most important - there is no free lunch.

Let's say you decide depth is more important so you hear all these rocks making a noise. You think they all sound the same so you listen for,the harder hit that means a "real" target. Problem is some of those hit rock sounds will be real targets you then miss.

There is no right or wrong answer. In general my feeling is it is always best to seek a smooth, stable threshold. As long as I can obtain targets by doing that it is the way I go. If the going gets rough and no more targets are to be found, I can back off the ground balancing to revelation more targets, most of which will be rocks, but some of which will be good targets.

The choice is yours.
