Until recently, divers were generally required to grasp a pair of handles and be towed along behind DPVs like the Bonex SubGravity Reference RS. But the AV2 Evolution, not unlike the Tusa SAV-7, breaks from this conventional travel mode. Similar to the Apollo AVX Extended Range, the AV2 Evolution provides multiple travel options. In addition to the old hands-on approach, divers can choose to be pulled single-handedly, or to ride in the saddle, leaving the hands free for anything from photography to water ballet. The Evolution also has extra grips to transport multiple divers.
Sea scooters and e-scooters are very different breeds. In spite of its popularity, the land-based scooter — seen by some as a reckless promoter of indolence and immaturity, by others as the epitome of our culture’s cavalier indifference to danger — is reviled for its dorkiness and explosive potential. Its underwater cousins, on the other hand, are revered for their ability to speed divers safely through treacherous waters. For as perilous as the sidewalks and streets of surface travel can be, they pale in comparison with the churning seas and submerged hazards with which divers must contend. In such a hostile environment, not only are the AV2 Evolution’s speed and range important, the freedom to use one’s hands defensively could be critical.
To that end, the Evolution uses a 25.6-volt / 20 amp-hour lithium polymer battery, delivering up to 120 minutes of continuous hands-free operation, with an average range between 7200 and 8000 meters. Constructed with a shock-resistant ABS resin body, it’s driven by a DC brushless motor and depth-rated to 90 meters. It has a 3-speed variable pitch propeller and progressive acceleration system. Thermal switch protection automatically shuts the Evolution down in the event of overheating. Weighing less than 50 pounds above ground, it will travel at 4 kilometers an hour when submerged.
For the money, it's the best on the market. You can easily pull two divers with it... Far more powerful than the high end smaller Seadoo. Really good quality!
