I just bought the at Pro. and had the opportunity to use it for an hour or so yesterday. was only able to dig up 2 pieces of buried aluminum siding that came up as a solid silver
some blatant differences:
the at pro
5cm increments ( 2" )
no surface elimination
pin pointing so far not as accurate ( strongly suspect user inexperience)
learning curve
Superior metal discrimination.
much lighter
water proof to 10'
no volume control/threshold
ground balance both auto and manual
gta 1000:
volume control
no ground balance
pin pointing very accurate.
1 inch increments
surface elimination.
next to no learning curve
heavier
mediocre at best metal discrimination.
housing not waterproof
