On the day after Hogmanay a good few years back, a nice sunny day and we decided a good dive would clear the cobwebs. I got paired up with a guy I wasn'tvery keen on,but the vis was 20m or so and it was flat calm - as we take hogmanay very seriously in the north,I said I wasn't prepared to go...

The water is at itswarmest in sept,so yes you can dive in a semi - but you might well be chilled for the second dive,as it's unlikley to be very warm on the surface inbetween dives. I go and dive scapa on my own fairly regularly - I just ring round the various boats and find one with spaces and...

With all due respect it is amphetamine based, a cns stimulant,that in adhd/add has a paradoxical effect as it stimulates the inhibitory complexes giving an increased attention span. Some drugs behave differently under hyperbaric conditions,most have never been,or never will be tested in this...

The original experiements on oxygen were on military 'volunteers' and its hard to put a linear progression on o2 hits -all it means is that 1.6 is the level at which,when on deco, you are unlikely to fit- although on long stops taking breaks is necessary on a low po2gas. Although it isn't...

Just give it a rinse off in fresh water and air it, probably not ideally in the full sun if you're somewhere very hot. Getting water inside isn't a big deal, other than it then becomes a damp-suit- it can be awkward to dry out the feet part. I got soaked yesterday, and just turned it inside out...

If you use a dsmb,the boat will be there to pick you up when you get to the surface

Fair point, I'd never thoughtabout it - I'd just hold onto them if I thoughtthere might be a problem,but it's never been an issueso far. I wasvery soggy last weekend, and struggled to get back in the rib due to water sloshing around my legs off Dunnet Head - much to the amusement of my buddy.

Which is why a basic openwater skill,taught very early on is the deployment of a dsmb,in shallow dives as all early dives are, from the wreck as you leave is fine,on deeper dives releasing it mid-water on ascent from 20-30m is the ideal. Every diver should be carrying a dsmb, and know how to use...

???? - I've been in plenty of rough waters and never had any real problem staying together once back on the surface, though I've had a few separations midwater due to tides/vis. I can't see how a long hose is going to help anything

# I think it depends on where you live and who you dive with which to alarge degree dictates the type of diving you end up doing. The club diving system ( scottish subaqua club in my case) covers all bases, but the emphasis is more on a slower progression with a lot of mentoring involved -...

MY geography is hopeless, but there are a number of operators in PLymouth who do novice sites and training if required. Not sure how new you are, but the james egan lane and the newer scylla are shallow and easy in about 22m. I would tend to stay away from any inland sites, but to be fair I've...

Port Skerra, Far North of Scotland, flat seas, sunshine, 62 minutes in 7 deg - through the archways, around the rocks and skerries, lobsters, lots of small fry starting to appear, dead mas fingers, devonshire cup corals everywhere - all within sight of Dounreay power station - then off the the...

In the red sea couple of years back, the guy who'd been a know-all all week, but a yoyo in the water was heard to say - 'what does sos mean on my computer?' - oh, says me, yu must have missed a bit of deco somewhere. Nope, he replied, I'm padi trained I don't do deco, it's too dangerous.....

Depends on what you mean by tables - I got bent using an early version of decoplanner - i cut the tables, safety etc, but failed to factor in everything, pushed the limits a bit too far one day on a 70m dive - since then have switched to a gf-based tables, the guy I dive with most hates them and...

The question was about back-up computers for novices, whic I don't agree with. They should have some sort of timing/depth device though - until they do, they are simply following and not learning as much, or taking any kind of control. When I started out, it was watches and depth gauges, I got...

But remember we are talking about new divers, not those doing anything deep or scary - loading a new diver, who already has lots to think about with more information than is necessary ( 2 different computers will often give quite different ascent times) can be counter productive

I gave my daughter ( age 17) nitrox 2 weeks ago to dive on one of the scapa flow wrecks, her deepest ever dive - she's not nitrox qualified, but she's got a reasonable grasp of phyisics - and we used to have a blending station in the garage, so she knows the score. Why? - I didn't want to push...

As a new diver, anything you do wil be both with a buddy ( hopefully a 'real' one) and well within no-stop limits, though doing a safety stop isnt a bad idea, and ensures a more controlled ascent. Therefore, your buddy will be carrying your back-up computer for you - and in the unlikley event...

My daughter learned at 15, in Shetland, cold water and some rough seas and loved it - she's now 17 and has left home to study, but when she's back we have great fun in the water together, there's no-one else I'd rather buddy - I'm having a fabulous time showing here all the things I've seen and...

There's never been and LDS anywhere near where Ive lived for the last 15 years. Dive clubs locally are the place to get air/gas - as well as meet new divers, get involved with training etc. However there are times when it is handy to have a shop to nip into - for that handy o-ring you seem to...
