Also the Poseidon XTreme is easy to service and works great for me when serviced. But you’ll need Poseidon Tools which cost a lot if you can get your hands on them. I lied about getting the ScubaPro for myself but would buy the Poseidon XTreme for myself since I can fix both ScubaPro/Poseidon’s all day long. For you the ScubaPro would be best since its hard to find a LDS that can service Poseidon’s correctly. Go with the ScubaPro line. I hope you decide to send your regs to a LDS with a full time reg. tec. Hope this helps with your question.
