Frequently Asked Questions
Does the Spare Air Model 300 Package Kit include a pressure gauge?
No, the package kit does not include a pressure gauge. A dial gauge is offered as an optional upgrade for all Spare Air models, including the Model 300, so you can monitor remaining pressure separately if you choose to add one.
Can the Spare Air Model 300 be used with Nitrox?
The standard Model 300 is not listed as Nitrox-rated. Spare Air offers a dedicated Nitrox-ready variant, the Model 300-N, which is rated for use with gas blends up to 40% EAN, so divers planning Nitrox dives should look at that version instead.
How do you refill the Spare Air Model 300?
The Model 300 refills from any full standard scuba tank using the included patented refill adapter, which comes with the package kit.
What is included with the Spare Air Model 300 Package Kit?
The package includes the 3 cu ft Spare Air unit, a holster with quick-disconnect straps and mouthpiece cover, a safety leash, a refill adapter, and a printed owner's manual. DiveCatalog also adds an orange whistle with lanyard for surface signaling.
