I didnt choose to be a padi diver based on padi but my LDS is a padi dive shop so thats what I went with.
So I guess really there isnt much difference??
The differences are minimal. The main differences are not noticeable to students, but tend to affect instructors more: such as how to conduct certain skill demonstrations or what skills appear in what order on what dive of the course etc etc
PADI is the most prevalent agency in the world - so the certification is known and understood globally. Also - they have a very good online certification database that other agencies don't have. This is very good for those occasions where you forget your cert card!
On the downside, PADI has a very standardised and popular instructor training scheme - and is often the first stop for wannabie dive instructors. While the instructor course is complete, standardised and well assessed - the shear quanitity of new instructors created each year means that any student has to be careful about their choice of instructor. It IS possible to get a PADI instructor with as little as 100 dives and 6 months experience!
Whilst other agencies may also suffer from this, it is less likely. Either way... it pays to ask some questions about your instructor before signing for a course.
Has anyone looked into these GUE guys? From what i have seen so far they seem to be top notch!
GUE are excellent, but expensive. They are well known for only training highly experienced and high standard instructors. The agencies history stems directly from technical and cave diving activities, which led to a strictly standardised system of skills and gear configuration. Over time, they developed this standardised system to include recreational diving.
Initially, this was in the form of the 'Fundamentals' course, that assessed and train potential cave and technical divers to a very high standard of 'core' diving skills.
The progression into entry level 'open water' training will see courses that have a very high emphasis on standardised gear configuration, high level core skill assessment, highly detailed dive planning and rescue techniques, amongst other things.
GUE is certainly the 'Rolls Royce' of scuba diving instruction. It fills a specific niche, that may or may not be ideal for everyone.
