October Meeting Highlights:

There were 12 present and 2 visitors at the meeting. Items discussed or talked about include comments on Lake 16 and the status of the boiler which has been removed and placed on display.

It appears that the DNR has no interest in the issue since its inland and
bottom land ownership is a riparian right and with permission of the bottomland
owner, objects may be removed. It has been suggested that an Ecology Dive be
performed at Diamond Lake to remind property owners that there are lots of junk
that can be removed from the lake and to perhaps leave the wreck of the South
Bed alone.

Under diver-related news, a discussion on diving without safety equipment, such as a safety sausage or such, was spirited. Surfacing far away from the boat with light fading is not where you want to be.

Several members havenoted their intent to attend Archeology Day in Lansing (Oct 19) and the upcoming Shipwrecks & Scuba Show in Sandusky, Ohio (Nov 23).

There was discussion on the future of the MUD club and what is necessary for it to continue. There is considerable activity on the MUD Club Facebook Site but the number of members attending meetings and events are basically always the same people. Many of the
core club members are getting older and are not as physically active as in the
old days.

We are looking for suggestions on how to generate more active participation in club activities. Suggestions at the meeting included having scheduled local dives with a lead
person who would be at every dive.

As usual, after the meeting several members Town Hall pizza.

Recent Diver Related Activities included:

An exploratory dive was performed at Diamond Lake to get a feel for the area used for recovery and obtain samples of the items which might be recovered.

FYI: It has been recently stated on the club site that the U/W platform at Lake 16 is now
vertical as either the chains or anchors have given way. Any updates?


Saturday November 23, 2019:

Adaptive Diving Unlimited will host its annual Scuba Diving Clinic with Mary Free Bed Hospital and Moby’s Dive Shop. Dive buddies and volunteers should arrive at 8:30

The High School is located at 2211 Lake Drive, East Grand Rapids, MI 49506.

We really appreciate ALL of you who are post about your dives on the “Mud Club” Facebook site. Other divers like to know where you dove, ease of access, the water temperature, thermocline level and visibility.  And especially what you see or find! 😊

There is NO reason not to be getting wet and/or having a buddy diver.  It is November and the water is getting chiller BUT it’s not HARD yet!  Get Wet Soon!

Diver News:
A DIN or a Yoke Regulator? It’s Time to Know the Difference.

There was a time when every regulator was fitted to a tank valve by means of a yoke
fitting (officially known as an International A-Clamp). The tank valve has an
O-ring, and most divers have been affected by annoying leaks and blown O-rings
because these can wear and fray. A DIN connection solves this problem, and
that’s why regulators are now available in both DIN and yoke configuration.

A DIN-fitting regulator has a permanently captive O-ring and screws securely into
the tank valve. Technical divers prefer them because the O-rings rarely wear or
blow, and the simpler shape of the DIN regulator, devoid of the yoke, means
there’s less likelihood of entanglement with lines and gear.

Another plus: DIN-fitting regulators with the required number of extra screw-threads
are rated for use on suitable tanks with higher pressures (up to 4350 psi), so
you can make longer dives. (Never use a yoke regulator on one of these
high-pressure tanks, even if you can find an adapter to fit it, because the
pressure is too high to be considered safe.)

With the rising DIN regulator popularity driven by the technical diving community,
you may think your American-bought yoke regulator will not fit tanks provided
overseas. Don’t worry. Most standard-pressure DIN tank valves worldwide are
convertible and accept a yoke regulator by means of a screw-in slug. Some of
these adapters offered by dive operators in distant countries look a little
tired, so prudent divers carry their own adaptor — they cost only a few
dollars at your local dive shop and take up no space in your carry-on.

If you decide to buy a new DIN-fitting regulator, you may have problems in the
U.S. or Caribbean because most tanks are A-clamp-fitting only and not
convertible. So you’ll need to add a yoke adapter, also available from
your dive shop.

Both DIN and yoke-fitting regulators are usually made from chromed brass. If you use
a yoke adapter made of lightweight aluminum, don’t leave it on your DIN regulator if you’re storing it for long periods. In the presence of seawater, electrolysis between different metals can make the yoke adapter impossible to remove later.

A cautionary note: In many European Union countries (but not the U.K.), tanks
designated for nitrox have a different thread (M26) than those for air (M25). Check with your dive operator abroad to make sure they have tanks that are used for both air and nitrox, in which case they’ll be suitable to use with either DIN or yoke regulators. M26 DIN-fitting regulators are normally color-coded green, are compatible with 100 percent oxygen, and are usually the exclusive province of technical divers.

Flotsam & Jetsam

A Pill to Treat the Bends?

The U.S. Navy has announced it’s researching the possibility that the common malaria prophylaxis, the antibiotic Doxycycline, may work as a treatment for decompression sickness, preventing severe effects. Studies are just beginning.

More Full-Face Snorkeling Mask Bans:
The Pride of Maui joins a growing list of tour boat operators that have decided not to
allow full-face snorkel masks on board while a state committee continues to study whether they may contribute to snorkeling deaths. In September, a 64-year-old Texas man drowned while using a full face mask in calm waters off Kaanapali Beach in Maui. In another incident in October, a 33-year-old Canadian man died while snorkeling with a full-face mask at Hanauma Bay.

Another Fatality on Closed Circuit.
Dr. Fiona Sharp, 55, from Perth, Australia, a well-known face in the technical diving
world, and a hyperbaric doctor who often gave insights into the medical aspects
of diving to Undercurrent, died on October 17 during a solo leisure dive to 295 feet deep on a reef at Bonaire. She was found unresponsive at 80 feet deep without the breathing loop mouthpiece in place in her mouth. She was using an Inspiration rebreather. The
dive had progressed normally until she reached her first deco stop.

Divers Corner:  CLUBS of TODAY

In 2019 many organizations and clubs have seen a sharp decline in membership over the past years. Clubs are losing members due to individuals getting older and not being physically as active as before and younger people are not joining or participating for various reasons.

With all that said do we just fade away or become a Phoenix? Your comments are appreciated.


Each diver must know that they are responsible for:

  • Their plan
  • Their execution
  • Their equipment
  • Their safety!

Anyone can call a dive at any time.

It is ALWAYS OK to say “NO!
