I like everything about it and I find the weight is not an issue for me. The two main features are the imaging and the true all metal with ID active. This really goes deep and is accurate. The pinpoint with the concentric imaging coils is dead center. I like the fact it won't tip over when set on the ground and I have my headphones on and I stand up. The headphone cord stretches but the detector stays anchored to the ground.
I sold my old treasure talk 2500 and bought a 2015 used 2500 PRO that does not have the treasure talk. The recovery is plenty fast enough and I like the imaging. I went out today and dug every signal. The imaging was amazingly accurate. You will learn when not to trust it. Sometimes the imaging will show differently when the coil is swept from different directions. If there is more than one object the imaging may be off and show a larger target. Using Zero Discriminate will let you know you have different metals in close proximity. I have started digging coins in these mixed signals. I did this today with a copper penny next to can slaw. The copper penny ID'd in the zinc area.
I have owned a lot of detectors including Minelab Explorers II and SE, XTerra, Sovereign XS and GT, Musketeer Advantage, Whites 5900, Whites Eagle Spectrum, Tesoro Vaquero, Garrett ACE 250, Compass Coin Scanner Pro, and Compass X-70. So far the GTI 2500 is my favorite.
