Bud, have used the GTI 2500 many times, the GTI 1500 since it was released several years ago and a whole season using the GTP 1350. Here is a simple run-down on these machines.
GTI 2500- This is the to dog of land machines that Garrett currently has available specifically for land hunts. Now this machine has a manual ground balance and a true all metal mode. What this does is give the operator an edge on depth and better performance in mineralized soil over the 1500 & 1350. The 2500 is a great relic machine, great for hunting in farmers fields, woods, beaches etc. It is also a fantastic coin hunting machine, as it can determine the size, depth and probability of a given target. It has several preset modes also, for hunting coins, jewelry etc
GTI 1500- this machine does everything the 2500 does except give you a true all metal mode and manual ground balance. So, you lose a little depth. But, there may not be any targets where you are hunting deeper then 4-5 inches. Both the 2500 and the 1500 give you 5 increments for target size. This feature is quite accurate for the first 6 inches, then the probability % drops off. The machine still continues to hunt much deeper though. Generally, if you get a reading for a coin sized object deeper then 4 inches, you will dig it any ways, as it will probably be old.
GTP 1350- This detector is the same as the GTI 1500, except that it only has 3 sizing categories.....small, medium and large. All small targets are coin sized, medium is bigger and large of course is pop can size or larger. The sizing ability on the 1350 uses different technology, but it is just as accurate as the 1500. There are also some extra little tricks that the GTP 1350 can do with its audio, in that it can be programmed to give a short audio sound for small target size, medium audio sound for medium sized objects and a long sound for large. The feature works well for night hunting.
So, what to do? Well, ask yourself what kind of hunting you want to do. If you want to go after relics, coins, gold, and plan on hunting in fields, the desert, beaches, woods, other cities etc......get the GTI 2500. If you strictly just want to go after coins and rings.....and generally be an urban derectorist, hunting in school yards, parks, backyards and even trails in woods or along creeks, the GTI1500 or GTP 1350 should serve you well. The GTP 1350 is a watered down version of the 1500. But......it gets the same depth and has a great sizing tool that will also help you leave the junk in the ground. I personally liked the GTP 1350 better, until the new imaging coil was available for the GTI Series. Now both coils are equaly stable, meaning that they don't false very much, when hunting in the woods. But...the GTI 2500 is the heaviest. If you plan to hunt on a weekly basis, this shouldn't be a problem, as you will build up some good endurance and will not suffer if you hunt all day.
Hope this helps......whatever machine you should buy depends on what type of hunting you want to do. Good luck with whatever machine you get Bud.
