Good morning, I did the advanced tdi many years ago and have never really used it. I need to use enriched air next year and would like to do a refresher course. I have been a regular air diver. Could you please tell me what options are available for a refresher course and what would the cost be roughly. Kind regards
I wouldn't worry about a refresher course as such then, I'd dig out your old course book and re familiarise yourself with the calcs and as far as using an analyser goes, they'll show you how their's works when you use it for the first time.
If you've been diving in between anyway it would be worth brushing up on ascents and general buoyancy skills as well.
