<font color='#8D38C9'>The reason we're doing the ERD course is that we don't have a deco procedures ticket. We learned our deco through the BSAC system, learning from books, talking to people & taking litle steps so haven't actually done a course. (maybe that's why i got bent ;¬)  
however after over 100 deco dives i'm not forking out for it now. It'd be like doing a drysuit course. With the entry level Trimix you need a deco ticket but i want to do excellerated deco which i belive the ERD course will give me as well as the deco ticket for when i move up to Trimix.
Will check out the dive centre though. Do you have a contact for their tech instructor?
Good diving
