Overview
A diver who wants an emergency air source clipped on and out of the way gets this Spare Air Model 300 in a black holster with a leash. The small aluminum cylinder is refilled with the included adapter.
It is built around dive safety and emergency preparedness rather than regular diving. How long the air lasts and how to fill it are not spelled out, so the manual and a qualified fill station matter.
Who it's for
Divers looking at a compact safety backup are the audience. Anyone who wants a tank for a whole dive, or a toy, should look at other products, despite the listing's kid and submarine tags.
Pros and cons
- Holster and leash included
- Refill adapter included
- DOT marked, made in USA
- Air duration not listed
- Fill pressure not listed
- Age and toy tags look like data errors
Performance notes
A small aluminum cylinder holds a small reserve of air, so the volume sets how long it lasts and the refill adapter sets how it is topped up. The holster and leash govern where it rides on the body.
