I just had to know. I took the D2 down to the city park, loaded up the factory DEEP HC, and bumped the discrimination up to 85, and started swinging. Within 5 minutes I had a signal with junk all around but hitting mostly a VDI in the 90s. Dug down and popped out a 1941 merc. I am very happy with the update so far.
I can't wait until I can put in some hunting time. I was there for a total of 20 minutes with the vast majority being getting down to that coin. It was only about 7", but somehow we had missed it all these years. I give credit to the update. The signal sounded great, like usual, but the difference was the VDI was yelling SILVER, instead of the usual 06-08.
