NO
I had the GTAx 500.
Man! It was so old, I had to rebuild the battery harness with
Radio Shack parts.
It worked, but it would not detect a woman's gold ring 1/2 inch
from the coil.
It would air test good on coins, but I never found a coin in the
ground very deep with it.
I was so disappointed!!!
I qutit using it and used my Bounty Hunter until I found Tesoro
uMax light weight detectors.
Now all I have is 5 Tesoro uMaxes.
Happy Huntin,
