Now, I am a carpenter by trade, and swing the detector with my hammer hand, so my opinion may not count. However my site is an old homestead in the middle of the woods, creek walk and thorn traversing included. Which is a bit tiresome to begin with. With all that, I have not once had a "dear lord this thing is heavy" moment.
The GTI 2500 features are there to do what they say and with a bit of practice(comes rather easily) you will find they do just that. There are no extras that you don't need(I-phone on a stick) but everything you do. Keeping up with the I phone comparison, if you are having trouble in a certain terrain/environment, "there is a coil or mode for that". It is truly a do all anywhere detector.
Downside: My current site(mentioned above) is full of iron nails when using the no motion pinpoint mode to pinpoint, it puts the detector in a all metal mode and the nails will then be detected.
Upside to the Downside:It takes about (2) nails, and paying attention to figure out when it is a nail you are detecting, and what the detector is telling you.
I personally spent about half a year salivating over the V-3 with every intention of going that route once I was ready. Luckily it took me a little longer to put together my investment than first expected, and after research on my own and through the knowledge here I changed my focus from the V-3 to a Sovereign GT, but being used to visual target ID features and not wanting to make a purchase I would regret I needed the best of both worlds, for me that decision ended up being the GTI 2500. If you visit the posts dedictated to the 2500 on here Sandman had some very helpful things to say.
In short(cough cough) if you have the investment and will not be satisfied with a more mid range detector, you will not be dissappointed with a GTI 2500 in my opinion, and many others as well. However as always the right detector is the one that you decide on and feel comfortable with in your personal style and search areas.
