I haven't tried mine on the beach... not many beaches in the Texas Panhandle. I'm satisfied with my 1400 coil. I initially thought is was a little heavy, but after swinging it for six hours today; I feel no worse for wear. It did take me a little while to learn how to successfully pinpoint. However, once I got it down, I was pleased with the results. (I found that once I found a target, if I held my pinpoint switch down and rotated 45 degrees, I could pinpoint the target - directly under the center of the coil). The depth of the coil is good in my soil (GND: 58-65). I was able to find a few coins in an area that I had recently searched with my stock 9.5 coil. I hope this info helps you make it thru until next Spring.
