Propulsion System

Dual-Speed Brushless Motor

The B2's brushless motor delivers a maximum static thrust of 8.5 kgf across both Power Mode (1.8 m/s) and Standard Mode (1.0 m/s) with minimal heat generation. The enclosed propeller cage ensures safety without sacrificing thrust efficiency — with stepless linear speed control for smooth 0–100% acceleration.

Battery & Charging

Sealed Lithium Pack · Magnetic Charge

The fully sealed lithium-ion battery is waterproof to the same depth rating as the unit itself — no exposed ports, no risk. The magnetic charging connector clicks into place automatically, making post-dive charging effortless even with wet hands.

Safety System

Auto-Stop · Wrist Lanyard · Thermal Guard

Three-layer safety system: the wrist lanyard kills the motor instantly if the unit leaves your hand; the enclosed propeller guard prevents contact at all depths; the thermal protection circuit auto-cuts power if the motor reaches unsafe temperatures.

Ergonomics & Design

Torpedo Form · Single-Hand Grip

At just 2.9 kg, the M1's low-drag torpedo body reduces water resistance for a more natural glide. The textured single-hand grip fits both adult and youth hand sizes, with the trigger positioned for comfortable extended use.

FAQS
  • Who is the M2 underwater scooter suitable for?

    A. The M2 is a consumer-grade underwater scooter intended for recreational diving applications. It is primarily designed for family recreation, snorkeling, pool use, travel, SUP activities, and underwater photography. It is suitable for first-time underwater scooter buyers and users who value portability and versatility. The product should not be positioned or promoted as professional rescue, cave penetration, or industrial diving equipment, nor should it be relied upon as the primary means of returning to safety, as doing so could create safety risks for the user.

  • What is the recommended age requirement for the M2?

    A. Users under 16 years of age must be proficient swimmers and must be continuously supervised by a qualified guardian who is thoroughly familiar with this product.

  • Can a non-swimmer rely on the M2 in the water? Can the M2 be used as a lifesaving device?

    A. No. The M2 is not a lifesaving device, flotation aid, or substitute for swimming ability. Anyone who cannot swim, cannot independently return to shore, or lacks the skills required for the intended water activity should not rely on the scooter to enter deep water. Appropriate safety equipment, such as a life jacket, buoyancy device, mask, or wetsuit, should still be worn as required for the activity.

  • Is a buddy required when using the M2?

    A. A buddy or observer is required. When diving or using the product in open water, follow the buddy system and do not enter waters alone where you may be unable to return safely on your own.

  • Can the M2 be used after drinking alcohol or taking medication?

    A. Do not use the M2 while under the influence of alcohol or medication, or when your physical or mental condition is unsuitable for swimming, diving, or snorkeling.

  • Can the M2 be used in strong currents, rip currents, or severe weather?

    A. Not recommended. Avoid severe weather, strong offshore winds, fast currents, hazardous waters, and any environment that the user cannot safely control or return from.

  • Can the M2 be used in water with heavy sediment, seaweed, or floating debris?

    A. Not recommended. Mud, sand, debris, seaweed, and floating objects may enter the scooter, become entangled in the propeller, or damage the propulsion system. Check water conditions before entering the water.
