Since the original model in 1999, the AB-911, which supplied enough air for a sport diver to get back up to the surface from sport diving depth, to the modern AB-2000 which supplies enough air for any scuba diver at any depth, no second stage regulator used as an alternate air source has even attempted to match the low maintenance trouble free record of the Air Buddy. The AB-XL adds nitrox capability to the AB-2000 features.
The Air Buddy needs servicing at least once every 2 years if it has been cared for properly. Proper care means little more than rinsing it in clean water after using it in salt water. It should be stored in the same way you would store any other scuba regulator.
The servicing includes complete cleaning and replacement of any parts that are not in proper working condition. For example, the valve seat will be replaced because time, ozone, heat and salt all work to deteriorate it.
Service also includes upgrading the Air Buddy to the latest model, regardless of what model you send in, for the same price.
The only model currently being made is the AB-XL.
If you have the old model, you may continue to use it or you can send it to us for service and an upgrade
