The Spare Air 300 with Dial Gauge package is a completely independent, compact emergency air system that was developed for divers to be able to take life-saving breaths during an ascent following an equipment failure or an out of air situation.

The 300 package delivers nearly twice the capacity of the 170 package, making it more suitable for ascents from a deeper depth. The Spare Air can be attached to your BCD in a convenient and easy to reach location using the included holster and safety leash. It can be rapidly deployed and is instantly active, ready to deliver the first breathe when needed..

The system can also be quickly handed to your buddy or another diver in an emergency, leaving you free and unrestricted by hoses and safety holds to perform your emergency ascent.

This Spare Air kit has been CE approved. Please be aware that there are copies of Spare Air products available from third-party sales platforms that state they are CE marked but have not actually been through the stringent testing procedure and therefore pose a safety risk.

THE KIT INCLUDES:
  • Spare Air 300 system
  • Dial gauge
  • Holster
  • Safety leash
  • Yoke cylinder filling adaptor

Excellent safety equipment, great quality.

I have the self reliant diver qualification and do occasional solo dives for videography. I purchased this on the basis it would be easy to travel with (I also bought the handy travel bag) and would provide a source of air in an emergency. It’s easy to use and provides enough air for a controlled ascent from the sort of depths I expected to be at. Only one annoying thing, it only comes with an International fill adapter and there is no way to specify DIN when you order it. I saw that a DIN adapter was available so I rang the store to see if it could be swapped and I could pay the difference (DIN fill adapter is £16 more than International) as I dive a DIN setup. Unfortunately the guy I spoke to said they wouldn’t be able to, so this means I will probably have to buy the DIN adapter as a stand-alone so there is less messing around. The kit wasn’t sealed in a package, so I think it could have been done easily. Maybe Mikes can contact the supplier and get it offered as an option in the future as the main UK importer? In use, this device is easy to attach to my BCD and really doesn’t get in the way. I will carry it on all dives as an extra source of air now and not just for solo dives.
