Last Meeting Highlights:
There were 21 in attendance at last month’s meeting, the Treasures report was very positive and though approval was given to purchase a new club ice shanty a replacement has not been found at this time. It was reported that the Great Lakes Shipwreck Festival in Ann Arbor was very good as usual and that the OWU display section was smaller than last year but that the program selections were good. It was mentioned that going to “Ghost Ships” in Milwaukee will be of value to anyone interested in an opportunity to learn about and try several rebreathers. There was reminders of Wolfs open house on the 19 & 20, and mention that a presentation on “What Lies Beneath-The St. Joseph River” in Buchanan, discussion on participating in the Midland Baptist Church Sportsman evening on April 23 and announcing that “Thirsty Thursdays” begin March 31. A question was asked if we were going to order any club jackets, hoodies, or T-shirts in the near future – No decisions made to date. Discussed underwater emergency tips, boat safety and methods to recall divers on a boat or shore. It was noted that the club will obtain a Papa (recall) flag for boat & shore use.
Papa flag – International Meaning: All personnel return to ship (or shore).
2016 Dive Listing:
Organize a dive and paste it on the Facebook MUD club site.
The water is still very chilly for most wet suiters so remember that the Club changing shed and heater are available for pickup with prior arrangement.
Come on down and join the fun on Thirsty Thursdays. All divers greatly appreciate “everyone” who comes and provides support for the activity. Dives can be labor intensive and “many hands make light work”. The gathering afterward for food and diving discussions are just about as much fun as the dive itself. J

Divers Corner: 5 Diving Tips for Saving Air
Do you breathe your tank down faster than your buddy? Here are 5 diving tips to help conserve your oxygen and extend your bottom time.
- Fix the small leaks
Even a tiny stream of bubbles from an O-ring or an inflator swivel adds up over 40 minutes, and may be a sign of more serious trouble ahead anyway. A mask that doesn’t seal is another kind of leak in that you have to constantly blow air into it to clear out the water. It’s also a source of stress, which needlessly elevates your breathing rate and thereby reduces your breathing efficiency. Does your octo free-flow easily? That can dump a lot of air quickly. Detune it or mount it carefully so the mouthpiece points downward.
- Dive More
Inexperienced divers are famous for burning through their air supply at a furious rate, so one of the best diving tips for saving air is to simply dive more often. You may not be a new diver, but unless you dive almost every week it’s still an unnatural activity. By diving more, your body will get used to the idea, and you’ll breathe less.
- Swim Slowly
The energy cost of speed is even more than you might think: Swim half as fast as you do now, and you’ll use less air.
- Stay Shallow
Because your regulator has to deliver air at the same pressure as the water, a lungful at 33 feet (two atmospheres) takes twice as much out of your tank as does the same breath at the surface. At 99 feet (four atmospheres) it takes twice as much as at 33 feet. There’s absolutely nothing you can do about that except to avoid being deeper than you have to be. If you’re making a transit over an uninteresting sand flat to get to the edge of the drop-off, do it at 15 feet instead of at 40 feet, and you’ll save air.
- Minimize the Lead
If you’re over weighted, you have to put more air into your BC to float it and be neutral. The inflated BC is larger (more drag) and requires more energy and oxygen to push it through the water. An extra eight pounds of lead means your BC is one gallon bigger when inflated enough to make you neutral.
