TUSA SAV-7EVO3 Underwater Scooter
Hands-Free Underwater Propulsion for Longer, More Comfortable Dives
Explore more of the dive site with a patented hands-free riding saddle, responsive variable speed control, and a powerful lithium-ion propulsion system.
The TUSA SAV-7 EVO3 is a diver propulsion vehicle (DPV) designed for scuba divers who want to cover more underwater distance with less swimming effort. Unlike traditional handheld dive scooters, its patented riding saddle allows the diver to maintain a streamlined position and steer using body movement.
For underwater photographers and videographers, the hands-free design can make carrying a camera system more practical during transit between shooting locations. Its maximum speed of 2.8 mph and published operating range of up to 5.9 miles make it particularly interesting for extended reef exploration and larger dive sites.
- Best for: Recreational divers, underwater explorers, experienced DPV users, and photographers covering larger dive sites.
- Main advantage: Patented hands-free riding saddle reduces the need to hold a conventional scooter handle throughout the dive.
- Camera compatibility: Can be used alongside independently carried underwater camera systems, but dedicated camera mounting compatibility must be confirmed.
- What makes it different: Saddle-based steering, variable speed control, three-step propeller pitch adjustment, and fold-out riding wings.
- Important tradeoff: At 45 lb with battery, this is a substantial piece of equipment to transport and handle on land.
- Before ordering: Note, the Underwater Scooter does NOT ship with a SAV-7EVO3 lithium-ion battery and matching SAV-7EVO3 charger. Please ensure you order these if you do not have them already.
TUSA SAV-7 EVO3 Quick Specs
Manufacturer specifications. Actual speed and range depend on conditions, diver drag, battery state, and operating speed. The scooter's operating-depth specification is not a recommended diver depth.
Key Features Explained
Hands-Free Riding Saddle
The distinctive saddle is the biggest reason to consider the SAV-7 EVO3. Instead of relying entirely on a handheld towing position, the diver can steer with body movements while riding the scooter.
For photographers, this can help when transporting a camera system between shooting sites. Camera handling should still be done only when scooter control and safe buoyancy can be maintained.
- Patented saddle-based riding position
- Body-directed steering
- Reduced dependence on continuous hand support
- Fold-out side wings for supported multi-diver riding configurations
Responsive Variable Speed Control
Speed control matters underwater because conditions can change significantly during a dive. A speed that works well in open water may be inappropriate near the reef, a buddy, or a photography subject.
The SAV-7 EVO3 features a rotational speed control system combined with a three-step variable pitch propeller. This provides adjustment options for different propulsion requirements.
- Maximum published speed of 2.8 mph
- Smooth, adjustable propulsion
- Three-step propeller pitch selection
- Useful for changing underwater travel conditions
Built for Extended Underwater Exploration
The SAV-7 EVO3 combines a shock-resistant ABS housing with a brushless motor and a dedicated lithium-ion power system.
An LED battery status indicator helps the diver monitor remaining power, while the system includes water leakage detection and a shutdown mechanism. These features support safer operation but do not replace proper pre-dive checks and maintenance.
- Shock-resistant ABS resin construction
- 24V brushless motor
- LED battery life indication
- Water leakage warning and automatic shutdown functionality

Frequently Asked Questions
Can I use the TUSA SAV-7 EVO3 with an underwater camera?
Yes, the SAV-7 EVO3 can be used while carrying an independently secured underwater camera system. However, direct camera or housing mounting compatibility has not been confirmed.
Does the TUSA SAV-7 EVO3 include a battery and charger?
It depends on the package offered. Body-only configurations require the dedicated lithium-ion battery and compatible charger to be purchased separately.
How fast can the TUSA SAV-7 EVO3 underwater scooter go?
TUSA lists a maximum speed of 2.8 mph (4.5 km/h). Actual speed depends on conditions, diver drag, and the selected propulsion settings.
How deep can the SAV-7 EVO3 operate?
The scooter has a published operating depth of approximately 230 feet (70 meters). This is an equipment specification, not a recommended dive depth or a substitute for appropriate training.
What is the difference between a dive scooter and a DPV?
DPV stands for Diver Propulsion Vehicle. Dive scooter, underwater scooter, and sea scooter are commonly used terms for underwater propulsion equipment, although designs vary considerably.
Can I take the TUSA SAV-7 EVO3 on an airplane?
The scooter's size, weight, and lithium-ion battery make airline transport more complicated than ordinary dive luggage. Check the battery specifications, airline dangerous-goods restrictions, and shipping requirements before planning air travel.
How should I maintain the TUSA SAV-7 EVO3?
Follow TUSA's instructions for freshwater rinsing, seal inspection, battery care, and proper storage. Inspect O-rings and contact surfaces before use, and avoid operating or charging damaged equipment.
What should I do if the scooter displays a leak warning?
Stop using the scooter, follow the manufacturer's fault-response instructions, and end the dive safely. Do not resume operation until the problem has been inspected and resolved.
