Garrett has a new waterproof model (Pro-Pointer AT) of the popular probe. I haven't used it, and can't say they improved the button/switch any, but they have included several good and needed features/tricks what it can do - besides, I'm still using my old Garrett with a plastic/rubber (Papa Doody) cover - so, when this (my second) Garrett probe croaks, I might get the Pro-Pointer AT, or a Nokta or Makro pointer...all three about the same cost, but waterproof!
update!:
I got the Nokta pointer yesterday, and successfully recovered two coins (out of three targets), in short order!
It was snowing wet flakes, but finding good stuff, in a fast efficient manner, was a real treat!
I love the pointer!!
My 2nd Garrett probe, the vibrator stopped working recently, so I sent it in for warranty work - it was good until April '16.
After being fixed, I'm giving it to a newbie, to whom I'm mentoring.
Pinpointers are essential detecting gear!!!
