I was wondering if any one has thought of using a chest mount booster/speaker with the LS. The same as the ones that work on the minelab units. After using the chest mounts with the GPX 4000 and the SD 2200D I can't stand the wearing of headphones anymore. Maybe some one with a bit of knowledge could look into making them there would likely be an interest. I don't have the knowledge or I'd do it myself. Cheers Nugget.
