I started out using the jackstay pattern but due to numerous trees my line kept getting tied up. A wise public safety diver told me that in zero vis searches, you need to just close your eyes and rely on your touch... so that's what I did. I only opened my eyes to check a gauge and to check compass. I just did your old 20 kicks south, 2 west, 20 north routine. It was about 50 yards off from where it went in. This thing has wings on it so I guess it "flew" quiet a ways before it came to rest. It was in about 28 feet of water and was much closer to shore than was thought. I had 4 boats pulling skiers and several jet skis buzzing above my head for hours. It was a fun mission.
