First test run went off beautifuly. Lake Ontario water was like glass. My Bud Jeff did as 20 minute sweep of a small area at 45-55ft depth. Viz was 20-30ft and was little to no worries about mask wobble or reg problems. Towed at a dead idle speed(3-4mph) Lots of time to check out the area, look at putor and compass. All in all a great day on the water... Stay tuned... Any questions please feel free to shot me a line.
