I recall you have also said that mild excercise may be beneficial. Is there a corelation between an individual's personal fitness level or strength and the amount of excercise/weight that is permissible? That is to say, is perceived effort a factor? For example, how would the limits for a...

I hope that's a joke. There's so many scammers out their preying on gullibility (especially of the elderly) that I could see someone trying that line as a means of getting inside the house.

What about filling the motor with glycol, like a submersible pump? Instead of keeping water out of a compressible air space, the seals only have to keep to incompressible liquids separated. Of course, it would affect the weight on land and the bouyancy in water.

Actually, it was the ultimate DIY project: http://www.aquascooterusa.com/aquascooter_story.htm Interestingly, I don't see the scuba reg adapter listed on the site. I thought he said it was an optional accessory, but maybe it was 3rd party or something he made himself. I never tried that part...

My brother has a 2-stroke gasoline piston engine powered u/w scooter that uses compressed air from a Scuba regulator. (It also has a snorkel for surface use) It runs forever on a couple of cupfulls of gas and will tow several divers around with ease. I never thought of the implications of the...

The Sherwood Blizzard is another model designed for use in very cold water. I don't know how it compares, but it is an option and I have seen the 1st stage sold separately, so you can buy an extra for use on doubles.

How can you tell when a firefighter is dead???? The remote control slips from his hand. ____________________________________ Lock a firefighter in a bare, windowless concrete room with nothing but two steel ball bearings, and when you come back in an hour he will have broken one and lost...

If that doesn't work, try filling it with baking soda and call it an underwater solid fuel rocket. :rofl:

Well, I'm sure there is the odd case. After all, if people will hurt themselves working to make money then anything is possible. My understanding of the BC situation is a little different however. The stories I hear are that the BC WCB is going to great lengths to suggest injured workers are...

My understanding is that dive shops tend to pick tough reliable regulators for rental units. So from that point of view, they should be good to go after a proper service and inspection. On the other hand, the rental units tend to be rather basic. So it may not be as fully featured as a...

I've heard that elsewhere too. I know a few commercial divers in BC, including my brother. Now this is the part that has me confused. BC divers have the knowledge to plan a safe profile, yet they dive unsafe profiles because there's no government enforcer hanging around? Is that by choice or...

I won't comment on the British Columbia WCB. Suffice it to say I've heard other horror stories about them. But other provinces are not necessarily that bad -- yet. However, I was under the impression that BC has some pretty stringent regulations in place governing commercial diving. A...

Mythbusters actually took a set of implants embedded in ballistic gel and an immersed in a measuring cup of water and played around with them in both a pressure chamber and a vacuum chamber. They did show some bubbles and slight expansion at 33,000 feet of altitude, but the bubbles were...

Mythbusters? If you have more than 1 cylinder, how about a cam-strap or ratchet strap and securing them to each other? That way they can't roll and you just have to block them from sliding.

Is there a script consultant's fee in this anywhere? :rofl: Just joking. But something that no-one mentioned to you yet is that below 80' (or so, depending on the person) breathing pressurized air leads to "nitrogen narcosis". Sometimes called "the rapture of the deep", the effect of...

Some brands have a mark printed on the outside of the plastic indicating where it is OK to cut.

Just imagine that the person is at the wheel of a full size school bus at the time. She did give up driving (and thereby lost her job) once we realized what was going on. However, the onset was gradual (over a month or so) and she didn't realize it was happening. She had been on the stuff...

I use an old Humminbird "Wide One deep" portable. Not as compact as those handhelds perhaps, but OK for on a boat and good to 600' with a 16° transducer. The case is around 10" square x 6" deep and holds two 6v batteries along with the display. The transducer has a suction cup to hold it to the...

Did my recert last week and that's not what they taught us. The Px should be removed from the metal. Throw a wool blanket under them first. Wet is OK provided the Px is not in a puddle -- defined as deep enough to make a splash if you stomp your foot. The issue is safety of the rescuer although...

Disclaimer: I am not a doctor, nurse, pharmacist or any other professional qualified to give any advice in this field. Normally I would not think to offer any advice about a drug, but in the case of amitriptyline... SWMBO was prescribed amitriptyline at a very low dose (10mg/day) for post-op...
