How to set up the Garrett AT MAX for the beach
Here is a good set up for running the Garrett AT MAX on the beach.
(1) Press and hold the power button until it peeps twice; this will reset the detector.
(2) lower the sensitivity on notch (bringing it 3 notches down from maximum) you will still get good depth.
(3) Select zero mode.
(4) Set iron disc to 43.
(5) Set threshold to negative 3(-3).
(6) Coil in salt water or wet sand auto ground balance the machine.
(7) manually lower the ground balance by 2 or three.
Follow these steps the Garrett AT Max should run quieter on the sand and in the salt water...if it starts to get chirpy again repeat the steps above as needed.
