Geneinno S2: lighter, cheaper, better
The Geneinno S2 underwater scooter is the follow-up to the brand's original Trident (now S1), designed to be lighter, more portable, and more affordable while preserving the core capability that made the Trident a standout: genuine underwater propulsion for divers, snorkelers, and water sports enthusiasts. At 2.7 kg and roughly the footprint of a 16-inch laptop, the S2 fits in a backpack or carry-on bag and deploys immediately at any dive site or beach.
How Does the Geneinno S2 Compare to the S1?
The S1 (formerly Trident) remains the deeper, faster option: it reaches 50 meters of depth, runs for approximately one hour, and moves at up to 7 km/h. The S2 targets a different user profile. With a maximum depth of 30 meters (100 ft), a top speed of 4.32 km/h (2.7 mph), and a runtime of up to 45 minutes per charge, the S2 is calibrated for recreational snorkeling and light scuba use rather than technical diving. The trade-off is significant weight and cost savings: at 2.7 kg and $399, the S2 is meaningfully more accessible than its bigger sibling.
Geneinno S2 Specs: Dual 350W Motors, 10 kg Thrust, App Control
The S2 runs on a pair of 350W brushless motors producing a combined 10 kg (22 lb) of thrust through a 4,400 mAh, 22.2V lithium-ion polymer battery pack (97.68 Wh total). Two speed gears (low and high) allow the rider to adjust to conditions. Battery recharges fully in 1.5 to 2 hours via the fast charger included in the kit. The companion iOS and Android app provides real-time readouts for speed, depth, battery level, and total distance, with additional controls for the integrated light effects and a self-cleaning mode that flushes salt and debris from the propulsion system after use in saltwater.
An integrated action camera mount on the S2 accepts GoPro and compatible cameras with matching connectors, making it straightforward to document dives without additional hardware. The unit is rated to 100 ft (30 m) depth, which covers the full recreational scuba certification limit, making it a legitimate companion for certified divers on leisure dives.
Portability and Travel
The S2's dimensions (500 x 270 x 148 mm) keep it within standard carry-on luggage size limits, and its 2.7 kg weight is easy to manage on a boat or beach. The battery capacity (97.68 Wh) also sits below the 100 Wh threshold that most airlines apply to lithium-ion batteries in carry-on bags, meaning the S2 is air-travel compatible without special authorization in most jurisdictions.
