Hi Guys.

Has anybody been able to use an At Max international successfully in salt water and in the saturated sand? If you have can you please respond with your settings. I've owned one of these for a year and a half and although I think it's a cracking machine on the dry sand and in any other environment, it provides nothing but frustration in the wet salt.. I've watched every YouTube video I can find on the subject and tried every combination of settings I can think of. I've tried to use the Max on beaches from Frazer Island to the Gold Coast in Queensland and it even had a quick try on a beach in Sandy Bay Tasmania. It has sucked on every beach (wet sand) that badly Im beginning to think Garrett should change the name to ST (some terrain). I'm not a beach hunter usually, but the ground is getting that hard where I live I was thinking it would be a good option over summer. I own a Sea Hunter so if I can't find a way to get the Max to run its not a big deal. Just would be nice to have some discrimination.

It's a single frequency VLF detector, so there is no real solution and your only recourse is to wind down the sensitivity to ease the ear strain. I agree that "All Terrain" is a misnomer - Garrett are well aware of this deficiency too, as shown in the AT Max manual:

AT Pro vs AT Max. beach test.

There is a few more tweaks that can be done but above info should be good for starters + I run my AT Pro in Zero and the AT Max in all metal on the beach just like when prospecting, so to me it's an "All Terrain" detector.
AT Max also have screen light so it's OK for low tide beach hunting at night!

I should update... I have actually worked out how to get it to run.. the trick is the frequency. My procedure is. Get to the salt water. Put the max in all metal and run threshold. Ground balance but then hold the coil about and inch off the wet... Turn up the sensitivity till it's unstable then flick through the 4 frequencies,,,,, one will be way smoother... At this point I back off the sensitivity 1 bar. Then run the zero mode but disk out to about 30,,,,, less if you can,,, depends on the beach. It works a treat and is as good as any other detector I've used. I'm happy anyway.. I think Garrett made a huge marketing blunder keeping the Max in the same chassis as the older At series. It's being overlooked but it's a great unit... When you select beach mode on the Nox,,, it's pretty much doing the above... The Garrett is just a manual machine. Once I realised this the beaches have opened up for me.
Cheers

AT Max work fine on wet a beach.

For max depth/sensitivity: Try ..... All Metal ... Notch out First and Last notch ... Reduce threshold 3/4 clicks below audible threshold ... now increase sensitivity to whatever it will take.

Experiment with settings!

The ATmax, is quite the detector.
Just have to adjust it manually.

Glad to see some people working it out.

Cheers.

1: Next step will be to getting the AT Max working on dry Black sand. ;)

2: After that it's the wet Black sand, that's the interesting part, to get the Max working at at full depth at one bar off full sensitivity. :D :perfect:
