My opinion is the GT is better than the NOX.. the GT's processor is slower but it finds deep gold and you will leave the bottles caps to the NOX users
I used to chest mount mine and stick it under my waders...
Its the best wet sand detector out there as far as I am concerned..
Dang Right!!!! And what's recovery speed when you lose depth!!! Not very many beaches have been to where I needed a fast recovery speed.
