Yellowtail from HongXiang is a compact diver propulsion vehicle engineered for underwater mobility, built to serve recreational divers, snorkelers, and professional underwater photographers with reliable thrust and intelligent power management. The system combines a high-torque brushless motor, a swappable lithium-ion battery, and a pressure-resistant composite shell, delivering smooth acceleration and predictable handling at depths down to 40 meters. Unlike many bulky underwater scooters, the products prioritizes portability, weighing just 8.6 kilograms, while still generating enough thrust to pull a fully equipped diver through moderate currents without excessive fatigue. This series includes products such as Frozen Yellowtail Whole Round, etc.
HongXiang designs each Yellowtail unit around a modular architecture, allowing users to replace the battery, propeller guard, and control trigger without specialized tools. The brand focuses on practical underwater performance rather than unnecessary complexity, which means every feature on the products serves a clear purpose. The hull uses glass-fiber reinforced ABS with 6061 aluminum internal bracing, giving the unit impact resistance while keeping buoyancy neutral to slightly positive. This balance helps prevent accidental sinking if the diver releases the scooter, and it also reduces wrist strain during long runs.
