The Diver Propulsion Vehicle or DPV is the smart ticket in maximizing the diving experience. By propelling the diver to the places of interest, the diver conserves oxygen and energy, two particularly valuable commodities 30 fathoms deep. The pro diver’s DPV tends to be fairly expensive and quite utilitarian in appearance. Many look pretty much like mini-torpedoes with grip handles and acceleration triggers, the Hollis H-160 being a notable example. Some, like the Seabob Cayago F7, present themselves as luxury watercraft and, at least in this case, the price certainly reflects it.
Sea Doo offers affordability and style with their sea scooters. They produce a wide range of highly functional products which challenge the primacy of some of the older scooter manufacturers. Many of their products outperform their more expensive, less design-conscious competitors, though some have sparked customer laments regarding cheap construction materials. A little research into product literature as well as consumer satisfaction can go a long way into making an informed purchase.
The Sea Doo RS series is 3 variations on the same structural theme. The RS1 is all black, the Sea Doo RS2 is a gray hull with black handles while the RS3 is bright yellow with black trim. The RS3 is the baby of the pack and weighs in at nearly half the price of the RS2, so it’s one of those rare affordable babies. All 3 are rated to 160 feet deep, with 130 feet optimal. The RS1 comes with Li-ion batteries, delivering 90 minutes of run time. RS2 operates with 75 minutes run-time while RS3 provides 60 minutes run-time. The batteries are replaceable and rechargeable which allows for longer diving runs, and the RS3 can use the batteries from either earlier incarnation. The Sea Doo RS series has cruise control, relieving the cramping stress of depressing a trigger. The triggers face outward to accommodate the thumb position during use. Neutral buoyancy is achieved through integrated ballast control which has a self-filling ballast hull. The RS3, like its brethren, comes with 4 lead weights and slots in which to place them in order to fine-tune buoyancy.
This SeaScooter is great for the ocean, lakes, rivers and pools lithium-ion rechargeable battery for long time . . . compact and easy to carry.
We also bring this to the lake when we go swimming. 3 mph may not seem like a lot but when you are underwater, it is fast!
The RS3 2015 model have a LI-ION battery, which is much better technology you do not want the acid type battery, which is heavier and less charge friendly.
. . . The plastic + metal bolt that screws in the top is incredibly fragile. It's a cheap plastic turning "handle" molded around a metal bolt.
