Equipment

After watching numerous episodes of Sea Hunt this weekend at work I have decided the following . I carry entirely to much gear and I need to work on my swimming technique . I think I need to get a me a new harness from Alan and go back to one of the double hoses I have . I also need to learn that swimmers crawl for moving thru the water .


cheers

Michael,

No, you don't "need" to learn a swimmer's crawl stroke underwater--that was done strictly for television and is not an efficient way of moving underwater. The instructors in the U.S. Navy Underwater Swimmers School made a lot of fun of looking like "Mike Nelson" in 1967, because they knew much of what was shown was not right. Learn a good dolphin kick underwater, with hands extended in front, if you really want to be more efficient in the water (the "frog kick" used by tech divers is extremely inefficient, and serves a purpose--keep from stirring up silt). If you want to be inspired by fast underwater swimming, take a look at immersion finswimming:

I would add to the list of required items a diving watch, and dive tables (which were used from almost the beginning of diving). And, while not really needed, I have almost always dived a snorkel, since the 1960s. The Hood Canal dive, shown below, shows me when in high school in about 1963 diving an orange, but round mask, Scuba Star regulator on a K-valve (restrictor orifice; I had just upgraded from a Healthways SCUBA double hose regulator), and a AMF Voit snorkel. That blue and white snorkel had a flex hose, and was ideal for diving with scuba.

Not only divers everyone has a watch ..I thought not need to add.. Your hero Mike Nelson and and we Europeans hero Cousteau didnn't use snorkel.
If there is a watch no need table , diver must be knows eveything.

Mike Nelson wouldn't use a snorkel as it didn't look good on film. Also, he dove in Silver Springs, Florida most of the time, and they changed gear underwater to facilitate filming.

Cousteau usually dived from a boat, which lessens the need for a snorkel. We have to remember that Cousteau alway was looking at how divers looked on film.

If you'll look at my photo from 1963, you'll see me near the shore. We swam on the surface a lot, and thus the need for the snorkel. Whenever you are swimming a lot on the surface, the snorkel comes in very handy. The same goes for diving rivers or in current. These photos are from the 1960s and 1970s of divers I have dived with in real situation.

Did you know that the British Governor memorize a logarithmic scale to Indian students in my country divers have memorize of dive table !

Snorkel is your way.. We dive usually deep so a boat wait us.. I like your photos however if you have BC or horse collar no need snorkel ..

My vintage 6+6 liters Scott twin AL tank’s positive buoyancy was bothering me in the dive.
I thought and resolved the problem. I made 5 mm thick 2 circle of lead and I had them on the bottom of the tubes Circles total weight are 2.4 kg. So the tanks became the balance.
