I just got a silver umax , and i paid 200 out the door , but it was used only two times, because the guy traded it in for a Ace 350 just could not handle beep dig , but that worked out good for me its like new so this means my compadre may have to go . but that is an amazing deal from what i have seen anything in the 4 to 6 inch is yours and maybe deeper , I hope to use the silver in the soccer fields keep us up on your opinions of the machine. one thing i like already about it is when you turn it on it does not let out an alarm that starts a heard of buffalos going and every head in the park turning to see what went off. I owned one before but never gave it a chance because it could not hit a dime a foot deep . now i know better depth is not all .
