Can Monofins be used for scuba?

Answer 1

You could use a monfin for Scuba. This is illustrated in the film the Big Blue but generally monofins are only used for free diving. There is a good reason why SCUBA divers a fin on each foot and why they are generally moderate in size. Normal fins give you a lot of control in the water. Swimming with a monofin gives you a very limited in finning technique which might cause a lot of practical problems unless you just want to swim.
