Two-Speed Underwater Propulsion

Choose between two speed settings and reach a published maximum of up to 3.1 mph/5 km/h. The simpler two-speed arrangement suits buyers who do not require the three-speed controls of the Navtech 2, while actual speed remains dependent on diver position, equipment and water conditions.

Removable Lithium-Ion Battery

The removable 21.9V 5.2Ah lithium-ion battery supports up to 60 minutes of normal intermittent use or 30 minutes of continuous operation. A fully discharged standard battery takes approximately 2.5–3.5 hours to recharge, and the removable design simplifies charging, storage and battery replacement.

100-Foot Equipment Depth Rating

The Navtech 3 carries a 100 ft/30 m equipment depth rating and is positioned for advanced divers. This rating describes the equipment limit only; it does not authorize a diver to exceed personal certification, training, gas-planning or environmental limits.

Water-Leak Monitoring and Protective Grilles

Front and rear grilles enclose the propeller area, while a built-in water-leak sensor monitors the unit during operation. If water intrusion is detected, the manual describes periodic motor interruption and an audible warning. Stop using a unit with suspected leakage and follow the official service instructions.

Compatible Camera Mount

A removable camera mount supports compatible action-camera mounting systems, allowing the camera to be positioned on the unit for underwater recording. The camera and attachment screw are not included, so buyers should confirm their camera interface and required mounting hardware before use.

Charging and Battery Care

• Switch the master control off, remove the unit from the water and dry it before charging.
  
• Use only the specified charger and follow the manual’s connection order.
  
• Keep the battery compartment, charging connection and sealing surfaces clean and dry.
  
• Disconnect the charger from mains power before disconnecting it from the battery or unit.
  
• Recharge the battery after use and at least once every six months during storage.
  
• Do not use, charge or transport a damaged, leaking, swollen or overheated battery.
  

Freshwater and Saltwater Care

• Rinse the seascooter with clean freshwater as soon as possible after use, especially after saltwater operation.
  
• Allow the unit to dry completely.
  
• Do not use detergent, and do not leave the seascooter stored in water.
  

Seals, Rubber Rings and Buoyancy

• Inspect, clean and lubricate the specified sealing surfaces and rubber rings as directed in the manual.
  
• Make sure the vent plug is tightened and the nose latches are fully closed before use.
  
• The unit is neutral-to-positive in seawater. It is less buoyant in freshwater and pools and may sink, so always test it before release.
  
• Navtech 3 ballast weights and accessory fins are separate accessories, not standard box contents.
  

Storage

• Remove the battery for extended storage.
  
• Store the battery partially discharged in a cool, dry, ventilated location.
  
• Keep the battery away from direct sunlight, heat, water, saltwater, metal objects and ignition sources.
  
• Protect the battery terminals from short circuits.
  

Age and Qualification

• The manufacturer lists the product for ages 16 and older.
  
• Children under 16 must never operate the product.
  
• Scuba use is limited to qualified divers; the manual requires a recognized diving certification card.
  
• The product is intended for personal recreational use, not commercial or rental use.
  

Operating Limits

• Do not exceed the 100 ft/30 m equipment depth rating.
  
• The rating does not extend the operator’s certification, training or personal dive limits.
  
• Evaluate currents, weather, water conditions and the operating area before entering the water.
  
• Stop operation and follow the service instructions if the leak sensor activates.
  

Air Travel with the Battery

The standard lithium-ion battery is 21.9V × 5.2Ah = 113.88Wh, or approximately 113.9Wh. Under current FAA guidance, rechargeable batteries rated from 101Wh through 160Wh require airline approval. Spare lithium batteries must be carried in the cabin, not checked, and their terminals must be protected. The traveler must confirm acceptance, packing method and quantity limits with the airline before travel. This battery is not described as airline approved.
