Just curious what everyone's thoughts are on a good sling or harness for the Equinox 800? I'm an older guy with a periodic history of minor back pain. Nothing major at all, just trying to prevent problems before they start. Is a harness a good investment or is it overkill for this detector? I don't mind spending the money if its really worth it, but the price tag on the Pro-Swing 45 is pretty steep. Any thoughts? I'm about 6'0" and 40" waist, so would that be a good option or are there better (or just as good) ones out there at a cheaper price?
