I was taught to put the console through the BC, under my arm and positioned so that the gauges were showing with just a need to glance down, I still dive this way and can always take a quick look at my gauges. I also dive with my left hand holding my right wrist so my DC is also in an easy to...

So far no one has mentioned another source of potential reimbursement, your credit card. Most card agreements are for that you pay the credit card for goods received or services rendered. If the airline cancels the trip BEFORE you start the trip then you should be able to claim the entire cost...

I am an engineer and used to doing calculation in my head. I can do SAC and RMV approximations using either metric ( MUCH easier) or imperial equipment. ( Actually i convert the imperial to metric in my head before doing the calculation.) I take a guess at my average depth to that point on the...

Speed of Sound in Water - The Physics Factbook "Sound is a type of longitudinal, mechanical wave. They need a medium to propagate and will not travel through a vacuum. Sound travels at different speed in different media. The speed of sound is determined by the density (ρ) and compressibility...

I am considering switching to a BP/w set up. Currently I have a traditional jacket style BC with integrated weight pockets. I carry 10 lbs. weight without my shorty and 12 lbs. with it on. This is about as close to optimal weight as I can get. I mostly dive warm tropical salt waters. Now...

A word on the law of home brew as I understand it. I am not a lawyer so this is only my understanding of the law. In Canada the law on distilling your own spirits revolves around the tax law. That is it is not illegal to produce it, just illegal to not pay the tax on it. However there is a...

Look on the bright side, when all these cruise ships get decommissioned, they will make some really greet artificial reefs and wreck dives.

It might get to that. Last week in Moalboal, I saw swat armed police, auto rifles and all the battle rattle, chase bikini clad beach bunnies out of the water for swimming.

I recall hearing about a news executive some years ago saying something like "Good news and bad news, for the first time ever the news division made a profit." Good news because all businesses are in it to make a profit. Bad news because once the news stops being treated like a public service...

I think that a lot of places, not only the dive certification agencies will have to rethink their time expiration policies due to this virus, especially if the restrictions go on. For example my car is due for its 10,000 km or 4 month service interval late this month. I am near the 10,000 but...

I grew up in the 60's in rural farming areas of Manitoba. While I was a town kid, my cousins were still on the family farm that our ancestors homesteaded 100 years before that. ( They are still there now.) I was about 6 so my cousin was about 9. We were visiting and my cousin had undertaken to...

I did not get my still from Amazon but it looks just like this one. Amazon Still Amazon Yeast Just follow the directions on the package. I heat the water so that the sugar will completely dissolve, it will remain in a super saturated condition when it cools, that is there will be more...

I just took pictures of my cards, front and back, and have that electronically on my phone, laptop, tablet. I also imported these into my electronic dive log app and have copies on all mobile devices as well as in my cloud account and on my USB drive on my key ring.. I also printed out these...

Not a diving example but one that shows that people practice what they were taught. I cannot vouch for the accuracy but was told this by an former member of the Royal Marines who was around when it happened. During the Falklands War the Royal Marines suffered an unusually high number of...

1. That level of CO is very quickly fatal at surface pressure let alone depth. A diver would not survive long enough to get to 40m. 2. If it is 1.5% concentration, it will be 1.5% concentration at any pressure. It will be 1.5% in the tank at 200 bar, the various gasses all come out of the tank...

Most of the importing I have done has been by a courier into either Canada, the Philippines or PNG. The couriers are all bonded customs brokers, they add a fee and do all the customs clearances for you and collect it COD. Amazon will ship with prepaid customs and duties based on an estimate and...

2019 Suzuki Vitara. I load everything I need to move around the Philippines from diving place to diving place in it. Great gas mileage, fun to drive and fits on the narrow roads here pretty good. And it has a sunroof as well. I use the sunroof to dump the heat out quickly when I start up...

We have all seen some pretty innovative dive shop logos. My favourite is Cebu Dive Center in Moalboal.
