String:Why would anyone want to go surface tether just for low vis? What you describe would eliminate 90% of diving in lots of places.
Gary D.:We spend a lot of time tethered to a surface tender but not between each other. Some of it is tied in while other times it is just holding the loop.
If two divers are hard tethered together and one gets into trouble you now have two divers in trouble. If conditions are that bad recreational divers don’t need to be diving.
