Global Underwater Explorers emerged out of a shared desire to safely explore and protect the underwater world and to improve the quality of education and research in all things aquatic. GUE is committed to developing safe, skilled and knowledgeable divers and it's training covers a diverse curricula, including recreational diving, cave diving, technical diving and rebreather diving.

Although most courses are run on site at Vobster, some GUE training programmes may require travel to locations other than Vobster Quay for training. Please note that course fees do not include the cost of gas and equipment hire (if required).

IMPORTANT - Education is purchased but certification is awarded based solely upon student performance.

Meet Your Instructor... Clare Gledhill There are few women involved in technical wreck and cave diving, but one of the most active, Clare Gledhill, teaches for GUE at Vobster. Clare moved to DIR diving very early in her diving career and completed all of her higher level training directly with GUE's founder, Jarrod Jablonski. She has been involved in the DIR-UK team for several years but is now also active as a diver and instructor in mainland Europe and elsewhere. Clare has logged over 1200 dives in a diverse range of open water and cave environments - from single tank reef dives to mixed gas multi-stage cave dives in France and Florida.

		GUE Primer £300 Two Days

The GUE Primer course is designed to introduce students to the essential skills required for sound diving practice. The course is non-certification; therefore completion of this class has no bearing on future GUE dive training. It is however designed to provide the recreational diver an opportunity to advance his/her basic diving skills, thereby developing more comfort, confidence and competence in the water and provide an introduction to GUE training while demonstrating the techniques necessary for success in future GUE courses.

Covering pre-dive preparations, inwater activity and post-dive assessment students will be encouraged to become aware of team-member location and concern for safety, responding quickly to visual cues and dive-partner needs, gain proficiency in underwater communication, basic proficiency managing a GUE equipment configuration. The class will work to gain safe ascent and descent procedures, two propulsion techniques that would be appropriate in delicate and/or silty environments and improve buoyancy and trim.

		GUE Intro to Twinset Diving £300 Two Days

GUE's twinset course is designed to prepare divers for diving a double tank/cylinder configuration using proper equipment and techniques. In this class, students will be trained in the use of double tanks/cylinders and in the potential failure problems associated with them. The course includes a minimum of 6 hours of academics & land drills and a minimum of four in-water sessions.

Advice will be given on kit set up and choices, and focuses on increasing proficiency with double tank configuration, through proper control of the buoyancy, trim, propulsion, teamwork and other GUE principles. Buoyancy, trim and ascent practice together with problem management and gas planning adds up to a worthwhile investment in training to use the new equipment.

		GUE Fundamentals £500 4 Day

The GUE Fundamentals course is designed to cultivate the essential skills required by all sound diving practice, irrespective of level or environment. GUE Fundamentals is a superb introduction to GUE diving and performs a three-fold function...

• Provides the recreational diver, who does not desire further diver training, with an opportunity to advance his/her basic diving skills, thereby developing more comfort, confidence, and competence in the water.



• Provides the diver with aspirations of more advanced diver training with the tools that will contribute to a greater likelihood of success.



• Provides non-GUE trained divers with a gateway to GUE training. Covering advanced buoyancy and trim, kicks, problem resolution, basic self resue and team resuce techniques, basic decompression management, gas planning and nitrox, GUE Fundamentals acts as a stand alone tune up for the experienced technical diver or an introduction to technical diing for someone wishing to move to the deeper or overhead realm.

		GUE Technical Diver Level 1 £800 5 Days

GUE’s Technical Diver Level 1 (Tech 1) course is structured to prepare divers for the rigors of technical diving and to familiarize them with the use of different breathing and decompression mixtures. Tech 1 training focuses on expanding the fundamental skills learned in the GUE Fundamentals course, and is designed to cultivate, integrate, and expand the essential skills required for safe technical diving. This will include problem identification and resolution, and building the capacity for progressively more challenging diving. In this class, students will be trained in...

• The use of double tanks/cylinders and in the potential failure problems associated with them.



• The use of Nitrox for accelerated and general decompression strategies.



• The use of Helium to minimise narcosis.



• The applications of single decompression stage diving, with respect to decompression procedures.

The class will focus on Nitrox and Trimix as breathing gases for dives down to 160 feet/48 meters, and provides an excellent foundation on which divers can build their technical diving experience and prepare for GUE’s Technical Diver 2 course (Tech 2).

The Tech1 course qualifies divers to use Triox 30/30, Trimix 21/35 and Trimix 18/45 as bottom gas, and one of 50% Nitrox or 100% oxygen for Decompression. The course is usually run over 5 days, but this may be adjusted to suit local conditions.

		GUE DPV-1 £400 2.5 Days

GUE's Diver Propulsion Vehicle Level 1 course (Open Water DPV) is a diver education program that introduces divers to the use of underwater propulsion vehicles. The course covers the basic principles of DPV diving and is designed to introduce divers to the skills and knowledge required for limited use of propulsion vehicles.

Training includes an emphasis on awareness, dive-planning, teamwork, environment, stress management, navigation, conservation, standard and emergency procedures, DPV maintenance and trouble shooting and the potential hazards of diving with a DPV. To qualify for this type of instruction, participants do not need prior DPV training, but must be proficient with advanced buoyancy control skills and high awareness level.

The GUE DPV 1 class is normally conducted over a three-day period. Teaching students how to hold proper position while using a DPV, deal with a runaway DPV, dive planning & operational planning, support, teams & team planning, gas planning & gas matching and considerations for managing and stowing a DPV while not in use - along with many other subjects.

NOTE - The GUE DPV-1 course requires all participants to have access to a tow behind-style DPV that meets course requirements for the duration of the course. A DPV that meets course standards is available for hire.

		Individual Training Days £POA On Request

In addition to the above formal classes, our GUE instructors run training days for divers who wish to improve their skills. No previous experience of GUE or DIR equipment is required for these days. Arrangements are made to suit the individual diver.
