S-2 diving scooter: Building upon the success of the S-1, Happy Walrus envisioned a two person scooter. After intense design and engineering, it is now a reality. Now couples can share the underwater experience in one environment. The second person at the controls eliminates any fear for the timid. The S-2 is perfectly suited for the couples and families to explore underwater wonders in a very safe environment. No experience required. The S-2 is a new high tech activity that is very safe, an exciting adventure and environmentally friendly.
