Is that the same Sammi?
Some people use the term "crush depth" to refer to the depth at which specific equipment can be at risk for failing due to water pressure. Divers going to those depths need to be very conscious of that risk with all their equipment. I would have to assume that this dive team was well aware of the pressure ratings of their equipment, so the scooter he had was probably rated to deeper than that. (I recognize that all that is assumption.)Is 'imploding' or flooding a common problem with scooters as, let's say, a frozen regulator in cold water and is there any relation to a regular maintenance of the device or is this just a case of brown matter that just happens and you can't do much about it?
Those ratings assume O-rings and shaft seals are changed annually and inspected regularly. Every time the scooter is opened to charge the battery you risk damaging the sealing surface and the O-ring. Every time the scooter is run out of water you risk damaging the shaft seal. At 20ATAs it doesn't take a lot for a failure to occur.My scooter (Cuda 650) is rated at 600 feet. When a scooter manufacturer establishes maximum parameters for his equipment, does he factor in a safety margin? I'm thinking of scuba tanks or hoses that have a usable pressure range and a bursting pressure limit.
What brand of scooter were they using?
Well, if the information on a Finnish newspaper is correct, it seems that the diver who came out after 500 minutes of dive time has some kind of problems following safe dive rules. He has now lost 4 buddies in a couple of years span and been given a ban to a Swedish mine.
