Agree 100% Most people on here shout from the rooftops about how much better a wing is.... well, I found it's roughly the same as a BC. The BEST feature I've found for my wing is that when I fully inflate on the surface I can still breathe! As for being more streamlined.. well what do...

How much is the $200 worth to you? If $200 isn't much money, then why not? If $200 takes more than a day to earn, then save your money.. It's not essential by any means, but it's useful for post dive analysis when you download your dives and log them on computer. It will calculate SAC...

I have been recently been TIG welding galvanized steel at home, which produces toxic fumes.. So a proper welding mask/active filter combo runs about $1800 which (in my opinion) is highway robbery. Setting aside clearance issues between the reg & the welding mask, I was wondering if I could...

Just to let you know.. some places are strict. My wife had a signed off medical to dive from a UK doctor, but to dive in Australia she had to have an *Australian* medical.. probably just moneymaking though...

Hey, THANKS for that link.. very interesting reading. AFAIK, there is no diving "laws" in QLD. There are workplace health and safety guidelines though - which is what that link describes. And most of those pages confirm what I already suspected - that most dive operators in QLD are full of...

Having not yet done a trimix course, I could be wrong... but I'd assume the reg choice would be influenced by the o2 in the mix rather than the helium since helium is inert. If it's your main reg and will only be used for trimix, the o2 wont go much over about 32% so any reg that is okay for...

I don't "believe in" 300 bar cylinders, for the reasons that you say are "not my problem". Roughly speaking, a 300bar 7L is the same weight and contains the same gas as a 232bar 10L. So why not just get the 10? You wont have problems with short fills (270 when you hit the water) or...

Even a Rolex is only accurate to -2 to +6 seconds per day - and that's the swiss "chronograph" standard, many are in practice less accurate than this. Once a manufacturer finishes a new movement, they send a certain number of samples to the certifying agency which then test just the movement...

Actually, I'm pretty sure it's the wall thickness that's different - ie. tanks over here have thicker walls and are heavier. I'm so glad I don't have to worry about overfills, etc. Most compressors in dive shops here go to 300 bar and I haven't met anybody yet that won't fill a 232 bar...

I wouldn't worry about it too much as most sensors are +/- 1% - which shouldn't make much difference to your dive planning.

No, a computer isn't "required". But neither is a BC. Or an Alternate air source. Or an SPG. But they do make life a lot easier.

I seem to meet two "types" of divers. The ones out on boats ("Holiday Divers") and the ones on here ("Internet Divers"). The Holiday Divers are waaaay too liberal with dive safety. They trust their computer, dive how often they want, get drunk every night and dive dehydrated the next day...

Faber is the most popular tank in the UK, Luxfer if you buy aluminium (Ali tanks are generally very rare). Thats why I prefer discussing the size of a tank by it's water volume - you don't get confusing conversations like this one.. Pretty much every tank is filled to 232 bar (300 bar...

I don't usually personally attack anyone on the internet, but man are you dumb.

This is the main reason I ascend vertically rather than the "cool DIR way" of horizontally. Your guaranteed that your shoulder is the highest point when you drop your left arm. Of course I get jiggy with it and go horizontal on deco stops, but the actual ascent is done vertically. (I'm...

I tend to agree. I feel SB pushes people towards a bp/w when they don't really need it. If your fine diving a jacket, keep the jacket. If you want to start going deeper and jacket doesn't have enough lift for the extra weight.. then upgrade. When I "upgraded", I didn't feel that much...

AFAIK, there is no such law. Apparently, there is some sort of "self regulating body" (don't know their exact name) in QLD that sets out "guidelines". These include: Always wear a snorkle, back on the boat with 50 bar, signing a dive sheet when exiting the water, no diving deeper than 30m...

I use the iRiver H340 (40gb). When I bought it, the iPod couldn't do usb host (the ipod photo hadn't been released). I've had no problems and have been happy with it. Another solution I have is if you have a little more space to buy one of the sony PCG laptops and replace the HD. They...

Thanks kapula. I'd love to go to the Similans, but it looks like I'll have to do it from a day boat. I'm used to "UK" vis which is .5-3m so 10m shouldn't be a problem ;) My wife has dived in the red sea & GBR so it may be a little different for her.. Thanks thien! I've booked/paid for...

Hi Thien, So are you saying it's better to just turn up & find some free space on boats? Or should we start looking around now for a good package?
