So the wife, not being use to the physical endurance of swinging her detector for long periods of time. She will get very sore and tired in a couple of hours in her arms. I have been working on something to help her support the detector. After seeing some harnesses and looking over the one she uses to support the weed whacker during the summer time. I realized that our day packs with the chest buckle, buckled up along with a couple straps and adjustable bungee straps I could make a harness that all she will be required to do is swing the detector and her core muscles will support the weight. Will try it out once weather allows us to get out. Once she hits a target she can either unclip the strap or simply move the detector over as the strap allows the freedom for that also. Anyone else done anything like/similar to this? I will post pictures if anyone is interested .
