Okay - here goes with my first 'stupid question post'. You will recall that Josh and I are the 'Novices' who joined a week ago or so. I want to buy a DSMB - what does the forum recommend? That's probably the easy and not so 'stupid' bit. Next bit - I saw some talk about formal training to use them. When in Tenerife last month we dived with more experienced folk who put up DSMB's and we accompanied them up to the surface. After 6 or 7 dives the Dive briefing for Josh and I was to tell the guide when we reached 50 bar. He would put up a (DSMB - he had 2) Hand it to me and off we could go. We used more air so it was to allow others to carry on 'bout us. After 40 mins or so we duly gave the 50 Bar signal, up went the DSMB and Up went Josh and I from 25m to 6m - nice and easy - stopped at 6m for 3 mins (as per the brief) and then plopped our heads up on the surface, gave the 'okay' and along comes the RIB and Hey Presto. When I chatted with the Dive Leader etc about DSMB's, he said as long as I practised in shallow first i.e. 5-10m - several times, I would be okay. He was being flattering at the time and said based on what he had seen we wouldn't have any problem at all and gave us some tips etc. Get to the bloody point I hear you say - Okay - is it okay for me to buy a DSMB - practice at Capernwray and go on from their or do I need formal instruction - I just know I'm going to luv the answers.
