Don't get me wrong, I love my ACE 250 but I didn't much care for my GTI 2500 as it was outmoded. The ACE is perfect for a run throught the local kiddie park or for simple coin shooting but I had a GTI 2500 for serious work. What I discovered was I could do almost as well with my ACE in most situations . The 2500 is so far behind the times it seriously needs a facelift or Garrett needs to invest in a new top of the line machine. I got tired of getting clobbered at the club hunts where deep hunts for silver quarters and silver dimes. The Minelabs and the Tesoros and Whites ate me up with their newer technology, I never could get any decent depth out of my 2500 even though I sent it in a couple of times to have it checked out. Six inches was tops for me. And the darn thing was so heavy it wore me out. I have a very bad back from an injury and the weight killed me. So I traded for a more modenized lighter weight machine and haven't looked back. But I loved the tones of the Garrett GTI 2500 and treasure talk and being able to see the size of the target was great. I miss that with my new whiz bang multi signal machines. But I can hunt all day with them without having to spend the night being packed with ice bags or hot tub surfing. So, common' Garrett, let's get some weight pared off and go multi-frequency. You're getting left behind. Do some updating and I am back in the fold. Just one man's experience and wishes. Onus
