I actually find it very reassuring in this world of ‘change for change-sake’ that Apeks don't feel the need to tinker with the important bits of something that is tried and tested across so many different models for such a long time, and has such a tremendous record of reliability and performance. They already have breathing characteristics that others makers envy (at least when compared on an ANSTI machine) so why spend vast sums re-inventing the wheel to chase a tiny improvement that will be imperceptible to the user, but that may turn out to be a less robust design and compromise the legendary reliability and destroy the hard-won reputation built up over decades? No much of a business model that is it?
A great many people literally trust their lives to Apeks regs on a regular basis for good reason, and knowing I’m not being used as a test dummy because someone in Aqualung thought it was a good idea to throw the baby out with the bathwater gives me a nice warm feeling when I need it most. Long may the smoke and mirrors continue.
