3.2 Product Feature
Established in 2018, Shenzhen Waydoo Intelligence Technology Co.,Ltd. is a high-tech enterprise
integrating research and development, production, and sales of water sports high-tech products.
With the experience of the R&D team and technological expertise, Waydoo launched the first
underwater scooter, Waydoo Subnado, through several technical innovations. Subnado adopts an
advanced built-in battery design, integrating a 98wh lithium battery, brush-less motor, motor drive,
control, and charging circuit inside an aluminum cylinder with a diameter of only 60mm, which
significantly reduces the volume of the product. Across the industry, Subnado is the first to use the
USB-C charging system, which supports fast charging protocols such as PD 3.0 and charges up to
100w for fast charging and charging other USB devices. The power system adopts the form of a
small diameter injection pump that achieves propulsion efficiency while obtaining up to 6.5 kg
thrust. The compact size and portability make it ideal for travel. Waydoo provides users with various
accessories, such as board and arm accessories. With the board accessories, users can leverage the
Subnado for propulsion power to suit a variety of scenarios. Users can fix the Subnado on the arm
without occupying both hands with the arm accessories, which is convenient to use underwater.
The quick-release & installation system design enables users to switch between multiple scenarios.
The Subnado provides you with the perfect experience underwater.

◆Two-speed thrust: The high and low gear provides two-speed thrust
options. Users can switch to the high or low gear by pressing the trigger
twice quickly. Users will hear one beep if they successfully switch to low
gear or two beeps if they switch to the high gear.
◆Super gear:Quickly press the trigger three times. When hearing three
beeps, users successfully switch to super gear; Within 1 minute, press the
trigger to start the propeller. The propeller will spin at the maximum speed
and provide the ultimate thrust.
Note: After one minute, the unit will automatically exit Super gear and
switch to the gear before Super gear. To re-enter Super gear, quickly press
the trigger again three times.
Note: The battery SOC should satisfy a specific range to enter the setting
gear. (refer to figure 1)
Note: When the battery SOC is below 25%, it will automatically switch from high gear to
low gear. When the battery SOC is below 37.5%, it will automatically exit super gear and
switch to high gear.
