They are both awesome machines, so either one you get, you cant go wrong. If you decide it aint what you want, you can resell it and get most of your money back and try a different one. Iam very partial to the 1350, I have also used a 2500, and and ace 250. Look at all of the features and see what you really want in a detector. Do you really need a detector to talk to you, maybe its your bag,, maybe its not.,, to me,, it would just draw attention from the bystanders, and thats not what I want.I am not a LOOK WHAT I GOT . kind of guy . do you really need to know what size the target is split into 5 different catagories, or is 3 enough. Is the extra size and weight of the imaging coil on the 2500 worth carrying around to get those 5 different sizes instead of 3. ? Do you want a true all metal mode or is an all metal mode in pinpoint enough? Do you want the capabilty to use the treasure hound eagle eye to look for large buried caches deep in the ground ? Do you need surface elimination to get rid of things right on top of the soil, or do you want to find everything? These are the basic differences between the 2500 and 1350. Just because one detector costs more and has more or different features than another, doers not mean it will be better than the other for what you want to do . You said you are a long time Tesoro user. I will tell you right now,, Garrett detectors DO NOT LIKE IRON!! .There will be times when you will do better going put the Garrett back in the truck and getting out your Tesoro. For deep detecting, in fairly low trash areas, with accurate target info, easy pinpointing, ease of use, and good ole fun,,Garrett is great. If you go somewhere and dont get many signals, , but you know there should be good targets theres a very good chance that the good targets are getting masked out by iron. Garretts operate at around 7 khz.. And they will find old silver coins and silver rings very easily. If I were looking for a gold ring, in alot of trash, I would probably grab my 14.7 KHZ Cibola. Different detectors do better at different things. I will tell you though, I wouldnt sell my 1350 for 1000.00 and thats alot more than I paid for it. Its just that good.
