    poseidon antifreeze cap how to use it?

    You fill it with vodka and then stretch it over the end of the first stage with the hex IP adjustment and fasten it with a very narrow zip tie. The alcohol is suppose to reduce the likelihood of a first stage freeze up. After a few dives the edge of the regulator body will probably bang up...

    The Perils of Ice Diving!

    A couple of years ago some fishermen who were ice fishing near where we were diving "caught" a package of Mrs. Paul's frozen fish sticks on their line. It was downright hilarious!

    Safety when tying off to a wreck

    It is not for bystanders on ScubaBoard, passengers or even crew to decide how to moor to a wreck. It is both the responsibility and duty of the captain to make the call. Every case is different and no method can be used effectively and safely at all times and in all places. It is his...

    TDI Technical Divemaster course

    As Wookie noted, the Technical DM certification is an important consideration for those charter operators who take out tech divers. Many charter insurance policies do not cover passengers once they leave (jump off of) the boat. The captain or mate's instructor or DM insurance will cover their...

    Cutting an Ice Entrance...Isosceles.Acute,or Obtuse

    I have always pushed the cut pieces down under the ice. I have never had any problem with it interfering with the lines - probably because I always use large diameter line. I no longer use a chain saw. I find that it is easier, faster and doesen't leave oil on the water when you use a hand...

    Wreck Diving

    I think my most memorable dive would have to be the one during which, bill Prince, Phil Patz and I found the name board and thus were able to positively identify the wreck of the scow, Tennie and Laura. My favorite wreck to dive is the freighter, S. S. Wisconsin. After hundreds of dives on...

    finger spool line in 2 pieces?

    One needs to be sure of the specifications of every component. The fact that a spool contains 4000 ft of line does not necessarily mean that it is a continuous piece. Unless specified that way it often is not. It is wrong, but easily understood how a reel manufacturer could make the mistake...

    Software?

    Does anyone still have a copy of Dr X that they are willing to send me? I used it way back when but lost it somewhere along the way. I would love to have it back just to show new tech divers the progression of what we are using now.

    finger spool line in 2 pieces?

    It is more likely that the line was joined by the line manufacturer than the manufacturer of the spool. It is common practice to join line by welding or tying it when it breaks in the manufacturing process. When the spool manufacturer wound the line on the spool they probably did not notice...

    Wreck diving and lighting

    Except in an emergency a strobe should NEVER be used in such a way that it is visible on the surface. A strobe light is an internationally recognized distress signal. It means the same thing as firing off a flare gun and may well attract unwanted attention.

    Snap Shackles & Dive Gear

    This is the type of shackle that is commonly used for the spinnaker sheets on a sail boat. They are designed to hold large loads and to be able to be opened while under load. They are useful for many rigging applications both on the boat and underwater. An example of a good application would be...

    Alfa is not appropriate for use on a shore dive. It has meaning only when flown from a boat.

    How many times diving the same site?

    I have done hundreds of dives on the wreck of the steamship, Wisconsin. I keep going back because I still have not seen all of it.

    Offseason storage -- did I screw up?

    I personally observed the results of a fire on several tanks. The tanks in question were all loaded aboard a boat for a dive which was to take place the next day. There were both aluminum and steel tanks. All were full and all had proper burst disks installed. During the night a fire started...
