The Marine 300’s 3.0 mph (4.8 km/h) top speed offers a solid balance between recreational comfort and forward momentum.

Powered by a 12V 12Ah lead acid battery, the Marine 300 provides up to 90 minutes of continuous use on a single charge — enough for back-to-back dives without needing to surface early. The battery recharges fully in 5–7 hours, making it convenient for multi-day dive trips.

The integrated camera mount allows you to attach a sports camera and capture your underwater adventures hands-free, while the heavy-duty rubber handles ensure a secure grip throughout your dive.
