Thanks Bill for the info. I mostly wanted the 2500 for the imaging part. Guess I'll have to come up with the extra coils. I have a Ace 250 with all three coils (6.5X9,9X12,4.5 sniper. Its a shame I can't interchange the coils. But the 2500 is 7.2 khz and the Ace is 6.5 khz. I also have a ADS II with 3 coils and Bloodhound two box attachment, but it also is 6.5 khz. Can you tune the freq down to 6.5 on the 2500? Just a thought, don't know anything about the 2500. I like the idea of the adjustable GB though. Wish the Ace had that function. Just started this year with the computerized detectors when I bought the Ace 250. Still trying to get used to them, I'm used to the older detectors. But detecting is a fun hobby no matter what machine you use.
Again thanks for the info and Happy Hunting.
