When I was in my OW class, I was told that some people do it to save on air consumption, they would be using air that otherwise would be wasted but the instructor also said that this was false ecpon0my as you would lose almost as much as you would save. I have seen a couple YouTube videos also...

I always thought that people who require SAR services due to stupidity should be responsible for the cost of those services.

I always believe in having any system that is critical have a redundant back up. My first (non diving) computer experiences were in the 70s when electronic systems were no where near as fail safe as they are now so backups, redundant systems is now just second nature to me. My reg set came with...

The missing skill here was not buoyancy control but doing the basic pre-dive checks. He should have tested his suit infiltrator, that would have caught the problem. Had the infiltrator come off in the water, he could have used his BCD to provide sufficient lift to surface, if his BCD was...

If you are properly weighted you should have no trouble descending with normal air volume in your lungs. With an 11 l tank you will lose 2 kg mass of air going from 200 to 50 bar. If you are neutral for your safety stop at 50 bar you will be 2 kg heavy at the start of the dive, that is...

I have my weight pretty much dialed in so I inflate my BCD a little once I reach depth to counteract the mass of air in the tank.Over the course of the dive I gradually release air to compensate for the loss of air in the tank and the fact that I gradually decrease depth as the dive progresses...

My cold water wet suit is a farmer john plus shorty. It gives overlap on the core helping maintain heat. I have used the shorty alone a couple of times in the summers so there is some flexibility. Downside is it takes a little squirming to get all the air out on initial decent but it is very...

Just buy it in your grand or great grand kids names.

Number one item on my bucket list, beat his record. Only 35 years to go. Is it too early to call in the Guineas Record people to give them a head up?

Be cautious in comparing pricing. While the course cost appears to be pretty comparable, you need to look at the inclusions and exclusions. Gear, in or rental, dive area fees in or out, boat fees in or out, agency fee in or out, etc. Right now I am diving with Cebu Dive Centre in Moalboal...

Take a mesh bag, put the wet suit in it. Put it in the water, work it around to get the air out of it, Take weights off your belt or out of the pouches until you can sink the bag with the wet suit in it. Leave that amount of weight, or slightly less, on shore when you dive. Adjust as...

I certified OW over Xmas New Year 95/96. I then dove at many resorts in the Caribbean and other places, dove with several dive shops, got air fills at more and dove with a couple of clubs. I was never asked for a c card until I started diving in the Philippines about a year ago. Since then 4...

I checked the PRA web site, they are accepting new applications but you need to make an appointment to the head office in Makati. Also the $US10,000 deposit option requires that a pension more than $US1,000 per month be deposited in a Philippine bank account, which can only be opened here.

The only use I see for spare air is to give you enough air to get to your buddy in case you are OOA at more than a couple metres away. However for the same money you can get a 19 cuft tank and have a real reserve if you want.

I disagree on buoyancy as being the critical skill. The basic safety skills, mask removal and clearing, replacing lost regulator, emergency assent, buddy breathing skills etc are more critical. You can survive a dive with poor buoyancy control, you might not survive if you lose your regulator...

On one of my AOW dives the instructor showed up with no mask. He had lent his spare to a student, not gotten it back then left his main mask sitting on the counter back at the shop. His truck had at least two of everything else in it, just no mask.

That sounds like a Special Residential Retirement Visa or SRRV. As of right now, SRRVs are not being issued and holders of them are not allowed back into the country unless they have a Philippine spouse or dependent or are former citizens. They are also only issued in the Philippines and you...

I like the bags from 511 Tactical. They come in a variety of sizes and have lots of MOLLE attachments. They are very sturdy. These allow you to attach pockets and pouches in many different configurations to meet your needs. Anything breakable can go into Pelican cases inside the soft sided bag.

I don't stress the air usage. If I have a reason to be higher than normal I will take that into account. So if I do a nice drift dive where there is not much to see other than just watch the scenery as you float past, and the boat moves to pick you up, I have one set of targets. I want to be 9...
