i have an AT Pro that is unquestionably my go to unit. it has produced. the 5x8 is the main coil. but i have learned the big stock unit, although my arm does not like it. Coinboy is youthful and can probably swing one better. when we get old the joints wear out. i do have a sniper coil, i call them hockey pucks, and one for my Tesoros also. they seem to be useless to me. i never find much with one. the sharpshooter 4x6 dd i had with my Mxt was a good smaller coil that produced.
i am like coinboy in if i can hunt the open, less trash i am fine with the performance of the big coils, and i have learned to adjust swing and movement with them. to a degree, its just the pain afterward. thats dictating what i use now. balance/ weight is a must. .
the smallest coils are my least favorite, the midsize just fine. the large work great for people with better joints.
kind of a 3 bears/coils thing.
May the last hole i dig be my own, and will a fellow detectorist cover me up. And you can have the pulltab!
