Mempilot, I am confused over this, as it was not how I was taught. I believed that a 1/2 life was 50%, 75% 87.5% etc. But my tec instructor says this cant be so & gave me the following as an example 'Halftime' is time to half way. Take your 20 min compartment. It starts at 0.79bar because...

Every year in Trang (Southern Thailand) near Phuket they do this on Valentines day. Usually around 20-30 couples in 10m of water. It is even in the guiness book of world records now as it is so popular

One of three whale sharks on this dive

SIXGEARS you tried to help & we got nothing, next trick "Wanting to buy some diving gear stuff" tell me what you have, & how much you want for it. Obviously she is not into sales

As PADI says "welcome to the family"

A lot of it comes down to where you dive. My wife has an intergrated BCD & we only dive in warm waters, normally above 26Deg C. She only uses 3Kg of weight so adding that to the BCD hardly makes any difference. She has dived with it for 6 years & never lost a pouch yet. The argument about...

It depends on who I am diving with & more importantly what diving I am doing. If it is deco diving then no all of use follow the same plan & stick to it. If it is rec diving we tend not to have a plan, jsut a few simple rules, max depth 40m, time approx 60 mins etc., we both breathe about...

Reefraker97, think you have made th right descion, wait until you have done a few more dives. Find out what sort of diving you like & make a note of the rental gear you have used & liked, & more importantly what you dont like. When oyu ocme to own your own gear you already have a shortlist of...

Personally i think that is the wrong order. I purchased my regs first, the reason for that is that they have only ever been in my mouth, I know they have been serviced & well maintained. People say they will never wear a wetsuit that somebody else has worn cos they may have pi$$ed in it, yet...

I use only Apex Black pearl for primary & back up. I also swap them around so that I know they all work & are all serviced at the same time. The only regs that I have different are the deco regs & they use the same 1st stage, but green/ yellow front covers to identify them as deco. They also...

I thought the purpose was two fold. To reduce the possibility of entanglement when doing cave & wreck penetration. ie the remainder of the strap not getting caught on the line Springs are less likely to fail than straps through wear n tear iebuckels & straps failing. Since then they have...

If it is only a little bit in the bottom of the mask, it is usually caused by pinching your nose too hard when you are trying to equalize. After several dives you should find that it will decrease & the more diving you do it will get better. Try not to squeeze the nose too hard when equalizing...

WHY NITROX? Nitrox provides a lower percentage of nitrogen than ordinary air. In this way less nitrogen will enter the body at a given depth and decrease the risk of two nitrogen-related problems: decompression sickness (DCS) and nitrogen narcosis. Both DCS and nitrogen narcosis result from...

It was taught when I did my ANDI course, but then they teach other things like carrying your own bail out. Ga smanagement & a lot of other useful things. With PADI doing the OW it was a case of been a doner & reciever breathing off the alternate. When I did my course we also had to do buddy...

They do make wetsuits with front fasteners. Have a look at Camaro. My wife has 3mm full with front zipper & loves it. I prefer the back zipper having tried both. Just seemed more comfortable & with it at the back u have nothing pressing the zip into you. As Captndale says it is also easier...

True, but look at how many other times this has been discussed on here & most people say they wont give away their primary. They usually come out with excuses like "why should I take my working reg out of my mouth & donate it". In my opinion everybody should be taught to donate their...

How mnay times do we see this question been asked. I think it was only last month.

You coyuld also try the modified flutter kick, or the shuffle kick. A good place to find out apout different fin strokes would be from cave books as they have developed a lot of different fin strokes to reduce silting

If it is possible to be taught to use it then it should be. Not all dive shops keep the Air II, but instructors should make students aware of them & how to correctly use it. Imagine never seeing one, diving with a buddy who you have just met on the boat & run into difficulites. Accidents are...

This should be a no brainer, learn to dive in the tougher of the two places, low vis, cold water would be my choice for the course. It will make you a better diver & appreciate the course. Swimming a 30m square in water where the vis is 20m+ is far to easy. try it with 5m Vis in cold water &...
