In a word - YES. I just spent 3 days hunting with one and did just fine. Many coins and a silver ring came my way. Honestly, these are the things the 1236 was made for.
The 1236-X2 is very good at separating targets, and has a lightining fast response. This means most targets hit cleanly in between the trash items (with the 8" coil). You can also swing it just about as fast as you want, as long as you dont get carried away - there is no need to poke the coil. In fact, a little speed will get you stronger and deeper hits.
With a little practice and some dabs of paint, you can soon tell when a target is in the pulltab range, too. The 1236-X2 will not tell you if the target IS a pulltab, however. No detector will. There are a few that come close, but the 1236 aint one of them. The best way to use it is to set it on IRON preset, turn the SENS up to 8 or above and just go to sweeping.
It is a deep seeker, has that good separation I mentioned and is a good iron eliminator. So it would do great on a freshie beach. Listen to tvr and get over your trash compulsion, at least on the beach. Oh, you will still find tabs and foil there, but the odds go up there for finding jewlery, too. When you take our advice and find just one nice ring (because you scoop everything above iron) you'll thank us, and probably stop complaining about trash..
