No, all they would do is magnify all the critters, alge and other stuff that makes up the turbidity in the water column.
Agreed. I have never, not even once, had issues seeing or identifying something under water due to distance other than when visibility is the problem. Now if you could come up with x-ray glasses that see thru the turbidity you might have something, but underwater binoculars? I don't think so.
That's why the Navy has Sonar for Submarines and whales have echolocation. When visibility is a factor. Optics are of limited use. That's also why underwater Photography is more challenging than topside.
yes it works, but it takes tons of hardware to do it, also it is debatable as to how healthy it is for the recipients of such signals. Having dove in an underwater sonar test range and having been literally shaken in the water. At this level, you can purchase commercial sonar systems for mapping the bottom, finding objects in the water, etc.
Unless the binoculars could magically see through turbidity, then they have no use. I've never been on a dive where my eyesight was the limiting factor - it's always visibility. What's the best underwater viz in the world? Maybe 60m? You don't need binos for that!
I would have far more use with a magnifying glass.
Handheld underwater mini-sonars are available. Useful for locating wrecks in bad viz.
