    Stolen Gear Please Help If You Can

    Have you called the Police? Make sure they have it on file. The Kijiji and craigslist checks are good ideas, as well as spreading the word around dive shops and clubs on the island.

    physics question

    ~sigh~ there is always one in every class that wants to read too much into the question;) The poor guy asked a question, based on similar questions asked in pretty much every OW diver course on how to do basic pressure/volume change equations WITHOUT using the P1V1=P2V2 formula. In 25+...

    physics question

    I am guessing here, but it sounds like a typical basic diving question so without going through all the stuff about where does it have seven Litres, what shape is it, what is it filled with.., to answer what i think you are asking.... take the ATA of your current depth, divide by the ATA of...

    Hand Signals

    That is a great link Thal, I had never read it before. Without hijacking the thread, you mentioned at the start that you were trimming it down for a book. Is it done? and unless it is a rhetorical question at the end, we would often dive three finger mitts and a shark sign is fingers...

    URL for PSD definition?

    Truth be told, we never use the term PSD. In our situation it is "police diver" because we are all police officers and if it ain't police related we are not involved.

    Units of Measure in Diving?

    Actually in Canada, while being a metric country the vast majority dive imperial units at the recreational level. Not sure about the techies... We'll drive 5km to the 100' dive, and fill our log books with the air temp being 24C and the water temp 57F

    PFD for muddy river work?

    Like Blades, we use the Mustang collar with auto inflate when submersed. Everyone wears one who is within 10' of the water. They are great for working in and are easily adjustable for summer or winter wear. I've spent full days in pouring rain where it was raining so hard I was considering...

    URL for PSD definition?

    A "task bank' for our dive program was done up a couple years ago, looking into the program and what the members experience and the report concluded with ... "... There is a frequent and sometimes extended exposure to danger/threats to safety (e.g.,explosives, contaminated water --...

    Yahooooo no calls

    You talking about the one in BC? After the fireworks on a large lake there, a speed boat went head-on into a house boat filled with families. The speed boat ended up inside the main compartment of the house boat. One dead(the operator of the house boat) and a bunch of injuries.

    NOAA or Navy dive manual, tables?

    If you are looking for "How to..." books, there are a number of really good text books out there. However if I had to list two "must reads" for PSD in the area of reference material I'd have to say.... Cpl. Bob Teather's (C.V.) book "Encyclopedia of Underwater Investigations" is still the...

    Tow Sled Best Option?

    A sled for diving is towed behind a boat, usually with a minimum 3 to 1 scope on the line (100' of rope out for a 30' depth). It allows the divers to be on the bottom (just above it actually) while the boat clears the area in a set pattern

    Tow Sled Best Option?

    How big is the boat? We sled with through-water comms but with boats 15' and under we have no problem relaying line signals up the line. Depending on how tight the boat can turn, we either go back and forth like plowing a field or if the boat needs more room we run a pattern like a zamboni...

    Ear protection in contaminated water.

    I'm gonna stick with my dry hood, thanks. Never heard of this one.....

    Tow Sled Best Option?

    We use them a lot. In some places I've been we probably sled 75-80% of the time. With some viz and a large search area and no drop sonar available, it is a very effective way to clear an area. Always two divers, either on a double sled or singles in site of each other. Through water comms...

    Surface swim-able shipwrecks

    It has been a few years now so I'm not sure of the surface access anymore, but I have done shore dives to the Hulda (out near Peggy's Cove) and the Perry and Illsworth near Chebucto head, plus the letita and Tribune. The CostaRican Trader, but I think the shore access is blocked now

    Contaminated Water

    Steve, Just picked up a copy of the new ERDi Contaminated Water Diving Operations book during a recent order. As someone who teaches this stuff on a regular basis, let me say "Very, very well done" IMO the best ERDi product out there right now. Kudos to ERDi

    Canada's best dive tour operator / agent

    It is not very well known..., we use to dive it all the time when I lived in the area and never saw anyone else there. There were two guys doing deep training stuff at 150' and we were 80' and their bubbles were hitting us on the wall, so it was pretty vertical. If you google "Gadd's Point"...
