You divers out there ever heard of a "buddy line"? In low visibility, that's a line that clips to you, and to your buddy.Creed:We were doing our advanced open water training. I had no choice of buddies. And given that I have dove in Kansas lakes with less than a foot of vis, I can see even good buddies wandering off in a split second.
In the 1970's, I had two belts made by our Life Support personnel at the 304th Aerospace Rescue & Recovery Squadron, with "D" rings on each side. The belt was made of 2 inch wide parachute webbing, with 5000 lb strength "D" rings sewn into it. I used a 1/4 inch braded nylon line, with two snap clips on it, to clip to the belts. I braded the snap clips into the line at each end, so that they were very strong. I believe the snap was rated at 250 pounds. The line was about 4 feet long. You had to decide who was to be on which side, then stay that way during the dive.
We proved out that system during a dive off the Oregon Coast at Otter Crest in December. We were out when the waves went from just manageable (about 5 feet), to 15-20 feet in just a few minutes. Coming back to shore, we were rolled by a very large breaker, and when we came back up, both of us were minus our masks. I had my helmet still on, and my buddy was right beside me (sans his helmet, which was held on by velcro rather than a neck strap). We helped each other find our second stages so we could breath (we were on the surface swimming in when we got rolled). We maintained buddy contact when being rolled by a 20 foot wave! We "proved the system" that day.
By the way, we got picked up by the U.S. Coast Guard about 3 hours later, thanks to our girl-friend shore observers. The Coast Guard personnel were really happy to see us, as we were their first live pickups in a number of months.
I'm enclosing three photos our girl friends took of us, the first prior to the wave, the second after the wave rolled us, and the third after they had called the Coast Guard and they were waiting without being able to see us for awhile. We were all pretty happy about the pickup, and my eternal thanks to the Coast Guard for coming out. They had a pretty hairy trip in with us, as they lost one engine coming in to Depot Bay. But we did make it. While my buddy and I were getting out of our wet suits (which, by the way, kept us quite warm), I bent over and had about a cup full of water come out of my nose from my sinous spaces. That wave was pretty powerful. We thought we'd newer make it to the surface. We had both ditched our weight belts, and I blew up my back-mounted BC and my vest (I had a Bill Herder inflatable wet suit BC at the time). Bruce blew up his vest.
You don't have to make belts anymore, as most BCs have ample "D" rings on them.

PS--Don't dive the Oregon coast in the winter. There's nothing between the Oregon coast and Japan but the Hawaiian Islands, and they don't provide much buffer from storm waves. I've seen this area have 20 foot waves on a bright, clear day (which this one mentioned above was not). I still have those belts, the line, and the helmet. Without the helmet (red, white-water helmet with white tape on the top), the Coast Guard would not have seen us.
