Here you go, for starters enclosed in the Pdf link below.
The 92 pages of:
Aqualung and Apeks Marine 2014 Full Spare Parts catalogue
See how internally nothing has changed in 25 years, its the same internal design, same internal parts, only the plastic outer contours and shape change and each year save only a fancy OTT black plating option, with a limited edition sticker for the "sheep"
See also in print this farcical $40 on line training course they offer for our local dive shop chaps to click on a few options and after they charge you to service your own stuff.
Its that simple guys couple of clicks on the internet and your done, kitchen sink, ultrasonic bath, couple of spanners and a LP gauge
And Apeks Marine/Aqualung wonder why as a diver I would prefer to service my own ?
I ask again why make the availability of genuine service spare parts to experienced divers who wish to undertake there own servicing any more difficult than it already is.
