I recently purchased my first detector a Prizm II and I love it. It's a great little machine and it finds EVERYTHING. The depth is outstanding too. I dug a penny at over 6" today in frozen dirt. Cans sound off as 50cents though.. I only hunt parks with it and they are quite trashy so when I get tired of digging pull tabs I discriminate everything but coins and I just pluck them out out the ground one after the other. One thing is that if it says its a quarter a quarter you will find. It's extremely accurate. The pinpointing is excellent, dead center of the coil, so I don't have a need to carry a handheld pinpointer. The speaker is loud and distinct, so I don't need headphones either, solid repetitive tones are the key to finding coins. Practice air testing on several different coins and metals, and on different settings first and you will quickly learn this machine. I'm so glad I didn't spend all the extra money on bells and whistles and extra gadgets to carry around. With the Prizm II it's all you need..
