Keep it! My son has a 250, I have a 1350. We both have sniper coils and I also have the big honkin DD coil. I like the 1350 much more than the 250. Don't get me wrong, the 250 is the best $200 you can spend. I have noticed that my 1350 is "right on ID" more than my son's 250. Last weekend we dug 150 coins side-by-side (you have to change the 1350's frequency to do this and not interfere with the 250) and the 1350 was right probably 90-95% of the time and the ace was right 50% of the time. Especially on nickles. My 1350 identified 10 different nickles as nickles and the 250 identified them as pull tabs. My son is wondering why he doesn't find many nickles and it is because discrimination has spoiled him. (me too to be honest) I would scan the target, write down the reading, then have my son scan it from same direction with the 250. He would write down what the 250 identified, then we would dig it up. Everything was clad so I can compare it on silver yet. I will admit that it has taken some time to get used to it. I have had it for 18 months and probably recovered 1,000 coins with it and 10 times that many pull tabs. I am just now getting very confident with it and my numbers have gone up. I used to get only a few coins in a couple of hour dig and I have recently got as high as 50 in a two hour dig ( I was sweating in 40 degree weather). Some of this is due to me learning where NOT to scan, some of it is learning the machine, and some of it is the 1350 itself. My thought is, you gave $500 - $600 for the 1350 four years ago. You might get $200 - $250 for it on e-bay being that old and used. You have a better machine now and will not get any money back in the exchange. Why do it? I will add that my recovery went way up once I added a quality set of headphones and learned how to adjust the 1350's sensitivity.
