Tried out the TDI SL for the first time tonight and I managed to snag a Rosie dime. The kicker about the dime was it was in the hole really close to a large nail. The tone was different than the nails I had been digging, it was like the TDI SL was seeing past the nail and only seeing the Rosie dime. My overall impression of the TDI SL is outstanding!!! Can’t wait to really learn this bad boy and see what else it pulls out of the ground!
