Hi everyone, new to the site, need some help. I have had a gti2500 for about 8 years. Used with limited success some most of it is probably the places i have tried to hunt. Have only found 1 silver dime and a handfull of wheaties, plenty of clads. I had the original coil on it until a few weeks ago when it broke. I got a new coil and now it does not seem to work the same, thinking the sensitivity may be to high for the new coil beeps on targets all the time. I have not been able to find many coins with the new coil mianly because of frustration and lack of knowledge with my detector. Even though I have had this detector for awhile I am pretty much a newbie, I had it put away for a few years because of lack of success. But reading thruogh these forums and seeing what everyone is finding wants me to get back into it. Anyone with experience with the 2500, can you help? Thanks
