Frequently Asked Questions
How many breaths does the Spare Air 300 provide?
The Spare Air 300 package delivers approximately 57 surface breaths, based on an estimate of 1.5 liters of air per breath. Actual breath count will be lower at depth because air is consumed faster under increased ambient pressure, so this figure is intended as a surface reference rather than a dive-time guarantee.
Can I refill my Spare Air myself between dives?
Yes, the 300PK-DG package includes a Refill Adapter that lets you refill the cylinder in seconds directly from any full SCUBA tank. No separate compressor or shop visit is required, which makes it practical to top off between dives on a boat or at the dive site.
What does the Dial Gauge add compared to the standard Spare Air package?</br>
The Dial Gauge gives you a visual readout of remaining air on the cylinder itself, rather than relying on an estimated breath count. Spare Air states the Dial Gauge upgrade works across its model lineup, and this package pairs it with the 3 cu ft cylinder.
Is Spare Air meant to replace a pony bottle or primary scuba tank?
No. Spare Air is designed as a fully redundant miniature SCUBA backup system for emergencies, not as your primary air supply. Its 3 cu ft / 85 liter capacity provides approximately 57 surface breaths, based on 1.5 liters per breath.
