GUE DPV I
18.104.22.168 Course Outcomes
GUE’s Diver Propulsion Vehicle Level 1 course is designed to introduce divers to the skills and knowledge required to safely use underwater propulsion vehicles in open water. Other course outcomes include: knowledge of the basic principles of DPV diving, dive planning, teamwork while using a DPV, environment and conservation awareness, stress management, navigation, standard and emergency procedures, DPV maintenance and troubleshooting, and the potential hazards of diving with a DPV.
Applicants for a DPV 1 course must:
1. Submit a completed registration form, a medical history, and a liability release to GUE Headquarters.
2. Be physically and mentally fit.
3. Hold insurance that will cover diving emergencies such as hyperbaric treatment, e.g. DAN Master-level insurance or equivalent.
4. Be a nonsmoker.
5. Obtain a physician’s prior written authorization for the use of prescription drugs, except for birth control, or for any prior medical condition that may pose a risk while diving.
6. Be a minimum of 16 years of age.
7. Have passed GUE Recreational Level 1 Diver or GUE Fundamentals at the “Recreational” level.
8. Have a minimum of 75-five logged dives beyond either GUE Recreational Diver Level 1 or open water certification.

22.214.171.124 Equipment Requirements
GUE base configuration as outlined in Appendix A, plus:
1. Approved DPV
An approved DPV is one that is tow-behind style with adjustable speed and clutch mechanism. The DPV must include an attached cord at the back with a bolt snap to be clipped on the front crotch-strap D-ring. The DPV should also have a leash attached to the front to be used for towing.
Prior to the commencement of class, students should consult with a GUE representative to verify equipment requirements and appropriateness of any selected equipment.
