Hi everyone. I'm working on an idea (for a project completely unrelated to scuba) and it looks like my best option may be the magnetic octo holder made for scuba. I'm trying to keep costs ultra low as this is an idea that may likely go nowhere. The trident one with the adjustable screw looks to be the most promising, but any will be helpful. Anyone have a used one they'd like to sell? Hope this is the right section, sorry if now! Thanks in advance! Sam
