Working shot pellet infestations is PERFECT application for Algoforce and sadie mk2. Still get the beep but flick to ID and if 00 keep moving.Nightjar. I was lying about needing kneepads for under the house. I really need them as I spend about 2 hours a day kneeling on the rocky ground in the Golden Triangle, praying that the next beep I'm about to dig up, is not the 175th bit of bird shot that I've found today, and will actually be a piece of gold!
