Daily Maintenance

DeepFlight submarines are designed specifically to require a minimal amount of maintenance, potentially even less than a normal tender boat would need.  The daily maintenance routine includes a freshwater rinse, battery recharge, refilling of the oxygen tanks and replacement of carbon dioxide filters as needed.  For additional information about maintenance, refer to our FAQ section.

Extended Warranty and Service Package

For long-term maintenance and health of your DeepFlight submarine, we offer various levels of extended warranty and service packages. This could include full replacement of any faulty component, as well as an annual servicing of  your sub by qualified DeepFlight personnel.
