For those who suggested "just go in" after that shotgun, you need your fricken heads examined. You might try a deep sea fishing rod (a short stiffboat pole) with some heavy60lb-80lbtest line. Get a couple of6 or 8 ounce sinkers to get you down there, then tie them off with a few good sized trebble hooks. Zip it down where you think your gun might be, and start dragging the area until you hook it. Then reel that bad boy up!
