If you want an introduction to the excitement of moving through the water with no effort, then this is your course. Covering ways to get the most out of using a DPV, as well as the things to take into consideration when making your dives – buddy contact, navigational concerns, the environment, and dealing with scooter problems.

Course Content

The course will cover the basic components and features of the scooter/DPV to be used and the steps involved in pre-dive set up. This can be conducted using the students own DPV, or rental unit from Tech Asia. We move on through dive planning considerations such as taking into account burn time of the batteries, and air supply when planning distances to be covered, and how to maximize the benefits of diving with a DPV. In our locality particularly, this gives the chance to dive some of our best dive sites, yet still be able to scooter back to shallow water for safety stops, rather than be faced with open water ascents that swimming divers would have to make. We essentially have the chance to make two dives out of one!

Safe execution of such dives requires students be aware of buddy tracking procedures, depth change considerations, entanglement hazards, and simple assists such as air shares. Dealing with equipment problems such as possible floods, failures, or runaway motors, whilst rare, is discussed and various solutions explored.

Confined sessions as required, and two dives are usually made, learning to handle the DPV used in the course being the essentials of the first, and having the opportunity to take more control over the planning and conducting of the dive being the purpose of the second.

 

Prerequisites

• Any certified diver may take the course, though it must be conducted within the depth limits of the students existing certification.
