HS-S1 Electric Underwater Scooter – Vector Scooter

Vector Water Craft Professional Electric Diver Propulsion Vehicle

The HS-S1 Underwater Scooter is a compact, high-reliability electric diver propulsion vehicle designed to deliver smooth thrust, precise manoeuvrability and dependable endurance for recreational divers, instructors and professional underwater operators. Engineered as a versatile core model within the Vector Water Craft underwater mobility range, the HS-S1 provides an ideal balance between performance, control and portability, making it perfectly suited for reef exploration, training programs, guided tours and light commercial support work.

Designed to extend underwater range, reduce diver fatigue and improve operational safety, the HS-S1 transforms the underwater experience by allowing divers to travel further, stay longer and work more efficiently with minimal physical effort. It is not a novelty device — it is a professionally engineered underwater propulsion system built to perform reliably in real-world diving environments.

Whether used by private divers seeking longer exploration dives, instructors conducting structured training sessions or operators performing inspection and support tasks, the HS-S1 delivers stable propulsion, intuitive control and dependable construction in a platform that remains easy to transport, deploy and maintain.

Compact Hydrodynamic Design for Efficient Underwater Travel

The HS-S1 has been developed around a streamlined hydrodynamic body that minimises drag while maintaining excellent directional stability. The elongated nose profile and optimised intake duct guide water cleanly into the propulsion system, maximising thrust efficiency and reducing turbulence around the diver.

Balanced internal mass distribution ensures neutral trim and natural straight-line tracking without constant wrist correction. This significantly reduces diver workload, conserves battery energy and improves comfort during long dives. The compact external dimensions allow confident navigation through reef corridors, wreck interiors and confined training environments, while the reinforced outer housing provides strong impact resistance.

High-Efficiency Electric Propulsion System

At the heart of the HS-S1 is a sealed high-efficiency electric propulsion unit engineered specifically for underwater use. The motor delivers smooth, continuous torque across the entire operating range, providing stable cruising thrust and responsive acceleration. Fully electric operation delivers several key advantages:

• Zero exhaust emissions
• No fuel odours or contamination
• Virtually silent propulsion
• Minimal vibration transferred to the diver

This quiet, clean performance improves diver awareness, allows close marine observation and makes the HS-S1 ideal for photography, training and environmentally sensitive dive sites.

Multi-Speed Electronic Throttle for Precision Control

The HS-S1 features an intuitive multi-speed electronic control system that allows divers to select precise thrust levels to match changing underwater conditions.

• Low-speed settings: Provide delicate, highly controlled motion for inspection work, buoyancy training and photography.
• Mid-range speeds: Enable relaxed cruising across reef systems.
• High power settings: Allow fast transits between dive locations and assisted returns to the boat or shoreline.

The ergonomic trigger layout allows confident one-handed operation even when wearing thick gloves or working in cold or low-visibility water.

Pressure-Rated Sealed Construction for Dependable Reliability

The HS-S1 is built around a reinforced pressure-rated sealed housing designed to protect electronics and battery systems at professional recreational diving depths. Precision O-ring sealing, internal reinforcement ribs and corrosion-resistant materials ensure long-term reliability in both saltwater and freshwater environments. All external fittings and fasteners are marine-grade and corrosion-proof, ensuring extended service life under repeated immersion.

Extended-Endurance Lithium Battery System

Power for the HS-S1 is supplied by a sealed high-capacity lithium battery pack engineered specifically for underwater propulsion duty cycles. The battery enclosure is fully isolated from water ingress and protected by multi-layer electronic safety management systems.

Intelligent power management maintains consistent thrust output throughout the discharge cycle, ensuring predictable performance. Advanced protection circuits guard against overheating, over-current and low-voltage conditions, extending battery life and enhancing diver safety.

Ergonomic Handling and Neutral Buoyancy Balance

Operator comfort is a defining feature of the HS-S1. The sculpted dual-grip handle system provides a secure, fatigue-free hold while allowing natural wrist alignment and relaxed arm posture during extended dives. The near-neutral buoyancy profile allows effortless hand-off, parking and hovering without the scooter sinking or floating aggressively.

Integrated Safety Architecture

Safety has been engineered into every aspect of the HS-S1 design. The fully enclosed propulsion duct eliminates exposed propellers, preventing injury to divers and reducing the risk of entanglement with lines, kelp and debris. Continuous electronic monitoring supervises motor temperature, controller load, and battery health. If abnormal conditions occur, the system automatically limits output or initiates protective shutdown.

Versatile Applications across Recreation and Professional Use

• Recreational exploration: Extend dive range and reduce fatigue on long reef and wreck dives.
• Training and instruction: Ideal teaching platform for propulsion techniques and buoyancy control.
• Resort and guided tours: Quiet, reliable scooters for premium underwater experiences.
• Inspection and survey work: Stable propulsion for hull inspection and marina surveys.
• Search and support operations: Controlled sweep assistance for diver teams.

Transport, Deployment and Low-Maintenance Ownership

Despite its professional construction, the HS-S1 remains compact and highly portable, fitting easily into standard dive transport cases. Quick-access charging ports simplify turnaround between dives. Routine maintenance is limited to rinse-down, seal inspection and battery charging, eliminating the complexity associated with compressed-air propulsion systems.
