Took the control box off the shaft. Attached a piece of flat Nylon belting to the box. Box hangs from my neck, behind me, between the shoulder blades. Tied the cable cord to my belt behind me to keep the box from shifting when I bend over. Works very well. Tried it today, found a 1925 Merc dime. River bottom is solid shale, no mud, dime was on edge wedged in a narrow crack in the shale. The shale bottom is flat and slippery as ice. I attached paint scraper pads to the bottom of my beach shoes. They gripped the slippery shale perfectly. Got the pads at a local Janitorial Supply store.
