I think the GTI is a waist for me if I have AT PRO to buy the E TRC you will need to swing match slower than the AT PRO the E TRAC takes match longer to process the information due to old age lol . E TRAC is a great detectorI love my AT pro.I have been thinking about getting a extra detector.I was thinking the GTI 2500 or the E-trac.Any suggestons ?I almost bought the GTI but settled for the Pro. I have found lots of relics but looking for more depth.
Consider the AT Gold. It has a true all metal mode (even more depth) and an adjustable threshold plus it's water proof. The other two are not water proof. The GTI 2500 also has a true all metal mode, plus it can size a target for you in the top 5-6 inches.
