I use the shoulder harness with bungie, when I dig the harness holds the detector off the ground, hanging by my side and it works great for me. It also takes all the weight off my arm when swinging........
This is what I made....3/16 plexiglass, Heat gun and some adhesive backed velcro. Light and removable.
Doesn't get in the way when swinging the detector. Had the plexiglass lying around.
