The fact is that you can get any of the annual service kits with internet shopping. Regs are basically built the same and basically the same to service except for an upstream regulator. I use to say the same about not being Rocket Science. Also would feel the same about sending my personnal regs to LDS just to have them messed up. Thats how I got interested with the dive gear instead of the teaching route as an instructor. I love the dive gear and always did before from day 1. So now customers would bring in regs just as an annual service. Never would anyone tell me that they went into the unit. I can tell 10% of the regs where attempts to repair themselves by not even being close to specs. I don’t say anything and just add a new annual kit then plus parts that are missing or distroyed. I’ll bench test and know the story before I take anything apart for servicing. But I feel good when I see the customer test with delight then tell me that its better then ever. The truth is that I could make it even better but I have to keep the units in spec’s so it doesn’t freeflow on a novice diver. You’ll have fun repairing your own set and saving maybe $50. And also the piece of mind that you know you did the service yourself correctly. All reg. brands have thier top end and low end regs. They are all excellent for the conditions that they were built for. Enjoy your Oceanic/Sea Elite’s. 350+ units serviced so far this year. Happy Diving
