The most durable regulator?

[Jack]

The Conshelf and Titan first stages are Royal Aqua Master derivatives, therefore they have proven longevity track record.

There are many good durable regulators in production today, but if you want a long track record with proven durable designs you basically have Aqua Lung (formerly US Divers) followed closely by Scubapro.

Sherwood has been around for a while and they have a good reputation, but they have had many design changes in the last 25 years. I don’t know an old Sherwood that holds any kind of following like a Scubapro Mk-5 / 109 or an AL Conshelf.

Vintage Mistral only tanks with 2500 psi or less, they have no intermediate pressure, and you can only add a pressure gauge with a banjo fitting. They are very likely the most reliable regulator due to their unmatched simplicity, but they probably would not fulfill today’s expectations.

Another good one. There is a lot of talk about what is the best or/and most durable regultor. I think in the todays market, with all the laws and regulations, that there is no BAD regualtors anymore. However there is a huge difference in the various regs and the preferences of the users.
Personally I am diving with Scubapro. The reason for this is that I have been taught with Scubapro equipment when I started to dive and I just stuck with it. Knowing a bit more about regulators today and also worked with a variety of different brands during my time as a diving instructor, I still think that Scubapro regs are great value. They are very reliable, durable and very easy to service. I am diving with a MK25 first stage and a S600 second stage, both as the main reg and Octopus. These regulators work very well within Recreational Diving as well as Technical Diving.
