For you people who question the ability of the Ace 350, this treasure was found at the beach in the SNOW today! Recently got this machine, and I am very pleased with it's ability for target separation and depth. It even likes damp sand without falsing. I previously owned a a Minelab Sov. GT and this has just as much horsepower as the Minelab. I am looking forwarding to getting the AT Pro and putting it against my Excal. This tests positive for 14k but does not have a marking.
