The SAV-7 EVO2 scooter DPV has been launched this past summer by Tusa, an American subsidiary of a Japanese corporation. The benefits of purchasing Tusa products have already been documented in a review of this dive scooter’s predecessor, the SAV-7 EVO Scooter so there is no need to rehash those points. You can also read in the review about SAV-7 EVO’s unique patented riding style which gives you additional freedom when scuba diving. This style has been carried over to the EVO2 as well.
The SAV-7 EVO2 upgrades on three important underwater scooters properties from its earlier version: battery, speed and range.
Battery and Run Time
The EVO2 is upgraded with a lithium-ion battery, a high-performing long-lasting battery compared to the lead-acid technology installed in the EVO. Lithium-ion batteries have been around for some time now and their power-to-weight ratios are substantially better than lead-acid batteries. Scuba diving scooter manufacturers have been slow in adapting the new battery technology and rightfully so. It is vitally important to ensure no battery leaks occur, irreversibly hurting the aquamarine environment divers absolutely love and want to preserve at all costs.
It was also important to be cautious with new technology adaptation for the battery as a security measure as a breakdown underwater could leave divers in potentially life-threatening situations. Tusa can be trusted with this upgrade and the new battery has a respectable runtime of 120 minutes. The diver propulsion vehicle also comes with a L.E.D. battery life indicator so you don’t have to worry about constantly watching your runtime underwater (especially annoying if you are regularly stopping and restarting the vehicle).
Speed and Torque
The new version of Tusa’s underwater scooter comes with a 10% torque improvement, particularly beneficial when utilizing the DPV to propel more than one person. Speed has seen a slight progress, budging up to 2.8 mph compared from 2.6 mps for the older model.
Enhancements in speed, torque and battery life all lead to one conclusion, which is to say the EVO2 has drastically increased its range from 2.6 miles to 4.5 miles in open water. This is a significant upgrade, affording greater flexibility to scuba divers for moving around in their dives.
Buoyancy is advertised as negative with the upgraded diving vehicle. This makes sense as the previous model came with a neutral buoyancy tag, but users reported the vehicle had a tendency to sink rather than hover when let go in water. The underwater device also has safety features like a water leakage sensor and sensation current shut-down device. Weight outside water, although not light, is a reasonable 45 lbs so an average adult doesn’t have to feel like they are heaving an impossible load when going for a beach dive. There is a 12-month manufacturer warranty attached to the underwater device.
The SAV-7 EVO2 scooter will cost you approximately $4,000. At this price, you are getting a well-tested, durable and reliable diving scooter renowned for its qualities and craftsmanship and a unique riding style any diving aficionado has to attempt at least once in their diving life.
