After going over the posts of the 1300 vs. 1500 I came to this conclusion. Really, the Garrett picture of the imaging feature helped me. It showed size "A" as foil and size "C" as a class ring. Now, if you're a gold hunter you know what that means. For reality's sake, you only need one size for rings, since they fall in the foil and nearby areas. Using the quick response for small targets and the profiling feature would seem the correct option. Now if I was strictly a coinhunter, the 1500. Thanks to everyone.
