I agree with locomotive. I use a nail apron from lowes . Trash on one side and keepers on the other. If the trash side fills up it gives me a reason to go to my truck and get a drink. HH
Bottom half of the Garrett back pack. Zipped tied a menards tool pouch to one side, and added a small magnet to the other side for the digger. Plenty of room for big, medium, and small finds. I like the magnet cause it's quick attach and release and holds well. Yes, I know it may not be the best idea for the electronic's, but I've got into a routine of pulling the carrot out when loading in truck and putting the pouch on the opposite side of the truck from my detector. And heck if I screw up, well time to upgrade. Works well.
Cargo pants pockets in my yard, Garrett pouch for normal hunts and water hunts, Gatorback Contractor Pro tool harness for when I'm far from the vehicle.
I use a couple of dove hunting pouches on a wader belt. The dove hunting pouches are for shot shells (originally) I put keepers one one side and trash in the other. Cheap from local sporting goods store about $20.
They have velcro flaps and are light weight.
