Turkey Dive – Seven Muddies got wet, 5 wetsuit & 2 dry suit divers, water visibility was in the 1′ to 5′ range, current moving at a hefty clip, water temperature was 40 to 43 degrees F. Four muddies were present for shore support. Some got wetter than they were planning on.

2016 Dive Listing:

January 23: Thrill of the Chill – time & place to be determined – check Face book.
February – -: Thrill of the Chill – TBD- updated on Face book & club site.
February 20: The Great Lakes Shipwreck Festival – Washtenaw Community College, Ann Arbor, MI.
February 26-28: Our World Underwater – Donald E. Stephens Convention Center, Rosemont, IL.
March 18-19: Ghost Ships Festival – Crowne Plaza Milwaukee Airport Hotel, Milwaukee, WI.

Organize a dive and paste it on the Facebook MUD club site.

Thrill of the Chill:

While we are waiting for the ice to build it has been noted that some of the local inland lakes are getting thick enough to walk on but not safely. The rivers are beginning to have some skim ice with water temperature in the high 30’s with visibility and current changing daily with leaf buildup along the shallows by the shore.

The Club changing shed and heater is available for pickup with prior arrangement.

Come on down and join the fun as a diver. Anyone who can stay as surface support for the divers will be GREATELY appreciated. Check and confirm buddies or support is available when you are diving

Divers Corner:       Life Ending Seconds
Did YOU know that a full 80 cu/ft. tank at 3000 psi goes to Zero very quickly:
At the surface – 0 ft. 1 ATM
A = Free flow regulator -> goes dry in 3 min 11 seconds
B = Low Pressure hose failure -> goes dry in 2 min 44 seconds
C = High pressure hose failure-> goes dry in +23 min.
At 66 feet / 3 ATM
A = free flow regulator -> goes dry in 2 min 53 sec
B = Low Pressure hose failure -> goes dry in 2 min 37 sec
C = High pressure hose failure-> goes dry in +23 min.
At 132 feet / 5 ATM
A = free flow regulator -> goes dry in 2 min 25 sec
B = Low Pressure hose failure -> goes dry in 2 min 8 sec
C = High pressure hose failure-> goes dry in +23 min.

Steps to stay Alive:
What do YOU do if at 100 feet your BC auto inflator valve sticks OPEN?
You pause to make that minor adjustment to your buoyancy and gently press the auto inflate button of your buoyancy compensator (BC).  Bang! Instead of adding just a “puff” of air, the valve jams and begins to empty the contents of your cylinder into your BC. It’s think fast, or face an uncontrolled ascent.
Risk Factor: Rapid or uncontrolled ascent, with attendant risk of pressure-related injuries.

Likely Causes: Probably the most common cause of a stuck BC inflator valve is poor or neglected maintenance. Some divers just don’t give their BC the post-dive attention it deserves. If a BC is not rinsed or soaked after diving in salt water, salt crystals and mineral deposits can form that can later cause the valve to stick in the “on” position. Another potential cause of a stuck BC inflator valve is sand, silt or other sediment in the valve mechanism. This can occur if the device isn’t properly secured and drags on the bottom.

Avoidance: Proper care of your BC goes a long way toward preventing stuck inflator valves. After each dive, or each day of diving, thoroughly rinse and/or soak the BC in fresh water to dissolve any salt crystals and to remove sand, silt and other debris. If it sticks or binds on the surface fix it before you dive it.

Dealing with It: The fastest way to solve the problem of a stuck inflator valve is to disconnect the low-pressure hose from the inflator but with cold fingers and 3 finger mitts that’s not easy. Failing that, grab the lanyard for the dump valve and hold it open. Should an unwanted ascent begin, continue venting the device, and flare your body to maximize drag and slow your ascent. Grabbing hold of a stationary object such as an anchor line might allow you time to sort the problem out and regain buoyancy control.

Reminder:
Have you ever thought on how you would respond to an emergency?

When in doubt, DON’T – Be safe out there!
