Note: This review is a bit limited considering I was only able to “test” it in the pool and not in a real ocean scenario. At least not yet!
This last weekend I had the chance to try my first DPV (diver propulsion vehicle), a Sea-Doo GTI. The Sea-Doo GTI, shown in it’s travel bag below, is a “mid priced” DPV that travels around 2.5 miles per hour, has a rated maximum depth of 100 ft, claims to provide up to 90 minutes of propulsion time and is priced around $400.
I was impressed with how light the GTI seemed – maybe 30lbs. Considering all the gear us divers are used to lugging around, the GTI seemed like a small accessory indeed. Once I was in the pool, I squeezed the two-hand triggers to get going and I took off. 2.5 mph doesn’t sound like a lot but remember you’re not putting much effort into getting up to that speed (saving air) and yet underwater you move pretty quickly.
I’ve never taken a DPV class, nor been certified on one but I assume the most important thing to remember when using one is to not ascend with it and/or ascend slowly. Diver’s aren’t supposed to ascend faster than 1ft/sec and with a DPV it can be very enticing to just shoot to the surface.
After about 30 minutes playing around in the pool and learning to streamline my body for less drag, I ended my GTI test. Until I get this thing into the ocean, I’ll never really know how handy / useful it can be. So that will be my next test. If I’m lucky I’ll be able to try it with the Sea-Doo VS Supercharged, the big brother to the GTI.
