H9-1 Electric Underwater Scooter – Vector Sub Runner

Vector Water Craft Professional High-Output Electric Submersible Propulsion Unit

The H9-1 Underwater Scooter is a high-performance electric diver propulsion vehicle engineered for advanced recreational divers and professional underwater operators who require greater thrust, higher cruising speed and extended endurance in a compact but extremely capable platform. Positioned near the top of the Vector Water Craft underwater mobility range, the H9-1 has been developed as a powerful long-range scooter designed to support demanding exploration, technical training, inspection work and structured professional operations.

Built for divers who operate in challenging conditions and extended mission profiles, the H9-1 combines a high-output electric propulsion system, reinforced pressure-rated construction and sophisticated electronic control into a platform that delivers speed, reliability and precision beneath the surface. It is not an entry-level recreational device — it is a serious underwater mobility system designed to expand operational reach, reduce physical fatigue and improve safety margins in professional-grade diving environments.

Whether used for deep reef exploration, long wreck transits, instructor-led technical programs or commercial inspection and survey work, the H9-1 delivers strong continuous thrust, exceptional control and dependable endurance in a form factor that remains transportable and practical for everyday deployment.

High-performance hydrodynamic design for speed and efficiency

The H9-1 features a refined hydrodynamic housing optimised to achieve higher transit speeds while maintaining excellent stability and efficiency. The elongated nose cone and carefully profiled intake geometry guide water smoothly into the propulsion duct, maximising thrust conversion and minimising turbulence around the diver.

Balanced internal mass distribution ensures neutral trim and straight-line tracking with minimal corrective input. This allows the unit to glide naturally through the water, reducing wrist strain, conserving battery energy and improving diver comfort during long-distance runs.

The streamlined body profile enables confident navigation through reef corridors, wreck interiors and confined operational environments while providing sufficient internal volume to accommodate a more powerful propulsion system and higher-capacity battery pack than mid-range scooters.

This advanced hull design allows the H9-1 to deliver higher cruising speeds without sacrificing endurance or precision control.

High-output electric propulsion for demanding underwater missions

At the heart of the H9-1 is a high-output sealed electric propulsion system engineered specifically for extended underwater duty cycles. The motor delivers powerful, continuous torque across the full operating range, providing rapid acceleration, strong cruising thrust and precise low-speed manoeuvrability.

Instant torque response allows divers to reposition quickly, maintain station in current and execute controlled movements around inspection targets, cables and fragile reef structures. Unlike compressed-air propulsion systems, the electric drive produces smooth, uninterrupted thrust with no pulsing, pressure drop or mechanical vibration.

Fully electric propulsion provides decisive advantages:

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

This quiet performance preserves situational awareness, improves communication between dive partners and allows close observation of marine life without disturbance.

Advanced multi-stage electronic speed control

The H9-1 is equipped with an advanced multi-stage electronic throttle system designed to provide precise control across a wide performance envelope.

Low-speed modes allow delicate positioning for inspection, photography and buoyancy training. Mid-range settings support efficient long-distance cruising, while high-power modes enable rapid transits, strong assisted returns against current and fast repositioning between work zones.

Progressive acceleration and deceleration eliminate sudden surges that could destabilise buoyancy or disrupt trim. The ergonomic trigger layout allows confident one-handed operation even when wearing thick gloves or working in cold or low-visibility conditions.

This sophisticated control system makes the H9-1 ideally suited for:

• Advanced recreational and technical divers
• Instructor-led long-range and propulsion training
• Professional inspection and survey teams
• Search, sweep and underwater support operations

Pressure-rated professional construction for extreme reliability

The H9-1 is built around a reinforced pressure-rated sealed housing designed to protect electronics and battery systems at advanced recreational and light technical diving depths. Precision O-ring sealing, heavy-duty structural ribs and corrosion-resistant composite materials ensure dependable operation in both saltwater and freshwater environments.

The casing resists deformation under pressure and provides excellent impact protection during rocky shore entries, wreck penetration and frequent handling in fleet environments. All external fittings and fasteners are marine-grade and corrosion-proof, ensuring long service life under repeated immersion and heavy utilisation.

This professional construction standard allows the H9-1 to perform reliably in demanding commercial, training and resort operations where equipment failure is not an option.

Long-range lithium battery system with intelligent management

Power for the H9-1 is supplied by a high-capacity sealed lithium battery system engineered specifically for high-output underwater propulsion duty cycles. The battery enclosure is fully isolated from water ingress and protected by multi-layer electronic management and safety systems.

The H9-1 delivers extended runtime suitable for:

• Long reef and wreck transits
• Multi-stage technical training programs
• Extended inspection and infrastructure surveys
• Guided long-distance resort excursions

Intelligent power management maintains consistent thrust output throughout the discharge cycle, ensuring predictable performance from full charge through to low-battery thresholds.

Fast recharge capability allows rapid turnaround between dives and efficient scheduling in fleet and commercial operations.

Advanced protection circuits guard against overheating, over-current and low-voltage conditions, extending battery life and maximising operational safety.

Ergonomic handling and neutral buoyancy balance

Operator comfort and control are core strengths of the H9-1. The sculpted dual-grip handle system provides a secure, fatigue-free hold and promotes natural wrist alignment during extended missions.

Trigger placement enables fine speed modulation with minimal finger movement, allowing precise control without disturbing buoyancy or body position.

The near-neutral buoyancy profile allows effortless hand-off, parking and hovering. Carefully tuned trim balance maintains a stable horizontal attitude, improving hydrodynamic efficiency and reducing shoulder and forearm fatigue during long operating periods.

Integrated safety and protection systems

Safety has been engineered into every aspect of the H9-1 platform. The fully enclosed propulsion duct eliminates exposed propellers, preventing injury and reducing the risk of entanglement with lines, kelp and debris.

Continuous electronic monitoring supervises:

• Motor temperature
• Controller load
• Battery voltage and discharge rate

If abnormal conditions occur, the system automatically limits output or initiates protective shutdown to prevent damage and ensure safe diver recovery.

High-visibility exterior detailing improves underwater recognition, while reinforced nose protection guards against accidental contact with reef, wreck and infrastructure surfaces.

Applications across advanced recreational and professional diving

The H9-1 has been developed as a true high-performance multi-role underwater propulsion platform:

• Long-range exploration diving – Cover large reef systems and deep wreck complexes with reduced fatigue and extended reach.
• Technical and instructor training – Ideal platform for propulsion technique, endurance and navigation programs.
• Resort and premium tours – High-speed scooter for specialty long-distance underwater experiences.
• Inspection and survey operations – Stable, powerful propulsion for hull inspection, marina surveys and infrastructure assessment.
• Search and underwater support – Efficient sweep and positioning assistance for structured professional operations.

Transport, deployment and low-maintenance ownership

Despite its high-output performance capability, the H9-1 remains portable and practical, fitting easily into professional dive transport cases and equipment racks.

Quick-access charging ports and sealed compartments simplify turnaround between dives. Routine maintenance is limited to rinse-down, seal inspection and battery charging, eliminating the servicing burden associated with compressed-air and petrol-based propulsion systems.

This low-maintenance design makes the H9-1 highly attractive for fleet operators managing multiple units across training, resort and commercial programs.
