Replacement Mouthpiece for Spacebox
Spacebox Mouthpiece is a replacement mouthpiece for the Spacebox 510 battery. It swaps in when your old one wears out or goes missing.

A small tear before the big dive
Horace has logged more than two hundred dives, and he still checks his gear like it is his first. On a dive boat off a rocky coast, he spots a small tear in his mouthpiece. The rest of his kit looks perfect. However, that one tiny part could spoil the whole morning.
So he digs a fresh one out of his dry bag, snaps it on and rolls backward into the blue. Down below, a slow sea turtle drifts past, as if to say well done. Your battery works the same way. When the part that touches your lips feels worn, a quick swap makes the whole device feel new again.
Why a spare Spacebox Mouthpiece makes sense
