Hi, I have a used but new to me Fisher 1265-X on it's way to me. There isn't alot of info to be found on the web about this detector. Not sure the size of the coil (will have to email where I bought it from to find out) but it is a soild coil, I perfer the spider type coils though. I am a coin/jewelry hunter at school grounds/parks/tot lots & hope the 1265 will do the job. From my understanding (reviewing) the 1265 is fairly deep/ built well/ a little on the noisey side/ & loves iron. Steve.
