What is the Best Underwater Diver Propulsion Vehicle?

As you can see from the three recommended underwater scooters, they are all by Sea Doo. They are the market leaders within the underwater scooters niche and completely wipe the floor of the competitors. Such competition comes in the form of brands such as Apollo and TUSA that cost a few thousand dollars.

Overall, the most popular underwater scooter is the Sea Doo Dolphin because it offers great value for money. The reason why this is important is that the majority of its life will be spent unused, unless you have a pool and regular hot weather. If that is the case, you could upgrade to the GTI or SD15001-RS1.

If you are looking for the ultimate underwater scooter, you are most probably a professional diver. The TUSA SAV-7 EVO-2 is built for people who are serious underwater explorers looking to explore the underworlds with the ultimate machine. The price reflects the seriousness of this DPV but you are also able to more than three divers at the same time, so could work out cheaper than buying three other premium DPV’s.

How do Underwater Scooters Work?

The underwater scooter is a battery powered gadget that features a propeller that is caged off from a protective grill. There will be two control triggers that allow the users to tilt the direction of the scooter to their intended direction.

Using high quality PVC material, the battery is fully waterproof (and so are any other electrical components) for reliable use underwater. Premium DPV’s can reach up to 5 mph, where the cheaper version will struggle between 1 to 2 mph.

Some diver propulsion vehicle machines will have buoyancy control to increase the speed through water. If the DPV is more buoyant, it will naturally start to float up, therefore the diver will need to force it to go in the straight line. Premium units have a buoyancy control switch to program it perfectly against your weight and use.

The underwater scooter is very easy to use and suitable for both children and adults. Due to the prices when they first came out, they were only really accessible to divers, but now prices have dropped significantly, which means snorkelers, holiday makers and more people can enjoy them.
