We sell and promote Halcyon products in association with Diving Leisure Leeds. We don’t just sell the gear we dive it and can offer first rate advice to future customers. We teach single and twin set configurations and although we practise Hogarthian/DIR we have an open mind and are happy to discuss anything including inverted set-ups. Anyone thinking of coming on a course can talk through equipment configuration and ensure they buy kit appropriate to the course. Contact Guy or Dave to discuss your requirements.

Dave Rowbottom has been diving since 2001 and is a PADI, EFR and more recently an SDI open water scuba instructor. Dave had a busy summer in 2009 logged over nearly 200 dives in some breath taking places such as Malta, Egypt and of course the UK. Dave’s love of wreck diving has taken him to some of the best wreck dives in Malta but also made him realise the importance of  Technical diver training to explore known wrecks more fully and discover  the deeper less dived wrecks. Dave is especially keen to teach scuba using Deep Techs preferred scuba configuration of Halcyon Eclipse wing with Cinch harness, H valve and dual Regs. This makes the transition to courses such as SDI Solo Diver and TDI Tech courses as smooth as possible! As Registered and currently practising Paramedic he has a love of teaching the most up to date and current information through Emergency First Response First Aid and CPR courses. Dave also holds the RYA level 2 powerboat award and numerous dive specialty instructor ratings with PADI and SDI.
