The Swim IT is reusable. You will need a new 16 gram threaded CO2 cartridge after each use. These are easily purchased at any bike shop for about $3.
Learning to repack your Swim IT is essential to becoming confident in your safety equipment and encourages early deployment of the device before a situation becomes an emergency. Our most successful and satisfied customers practice at least three deployments and repacks before using the Swim IT on training swims or races.
WARNING: All Swim IT deployments are to be done in the water (wet). Dry land deployments may void warranty.
