Overview of September Meeting highlights:
There were 15 members in attendance at last month’s meeting and we welcomed our newest member (and first to pay 2014 dues) Randy Baggiani. Treasure report identified we are still solvent. Most of the meeting involved discussing dive related events on wrecks or in local lakes. These included MUD club picnic and river drift dive held August 24, in Niles Michigan at River Side Park, information on the Mackinaw & Cheboygan Wreck, Trash & Treasure & Diving Week which included diving the Cedarville, Stalker, Sandusky, Saint Andrew, Jenny Lynn, and rubble wrecks the Genesse Chief, Leviathan, and Islander. Grubbing was performed in Duncan Bay and the Cheboygan River. Local dives were at Gull lake, Eagle Lake, Lake 16, Paw Paw lake and our river dives in Niles. Referenced Wednesday evening dives have ended and SASS pickup weekend dives have began. Feedback provided on Wolf’s annual flea market.
Its autumn dive time, the local waters are still “soft” but definitely getting cooler. Get in now and get wet before the hard water sets in.
The Healthy Diver: Tips for Clearing Your Ears – by Selene Yeager
Ear woes are the No. 1 reason divers pull the plug on a dive, and in extreme cases, the sport itself. But with a few tricks and advanced techniques, almost anyone can make equalizing easier. In diving, the Valsalva maneuver is often used on descent to equalise the pressure in the middle ear to the ambient pressure. Performed properly — pinching your nose shut while exhaling — most divers can descend without any problems. But for some divers, the technique doesn’t help.
You should never continue with a descent if you are experiencing ear pain. But before you give up on a dive — or diving itself — try these tips.
Listen for the “pop.” Before you even board the boat, make sure that when you swallow you hear a “pop” in both ears. This tells you both eustachian tubes are opening.
Start early. Several hours before the dive, begin gently equalizing your ears every few minutes. Chewing gum seems to help because it makes you swallow often.
Equalize at the surface. “Prepressurizing” at the surface helps most divers get past the critical first few feet of descent. It may also inflate your eustachian tubes so they are slightly bigger. Not all medical authorities recommend this, however. The lesson here is to pre-pressurize only if it seems to help you, and to pressurize gently.
Descend feet first. Studies have shown a Valsalva maneuver requires 50 percent more force when you’re in a head-down position than head-up.
Look up. Extending your neck tends to open your eustachian tubes.
Use a descent line. Pulling yourself down an anchor or mooring line helps control your descent rate more accurately. A line also helps you stop your descent quickly if you feel pressure.
Stay ahead. Equalize often, trying to maintain a slight positive pressure in your middle ears. Don’t wait until you feel pressure or pain.
Stop if it hurts. Your eustachian tubes are probably locked shut by pressure differential. Ascend a few feet and try equalizing again.
Avoid milk. Some foods, including milk, can increase your mucus production.
Avoid tobacco and alcohol. Both tobacco smoke and alcohol irritate your mucus membranes, promoting more mucus that can block your eustachian tubes.
Keep your mask clear. Water up your nose can irritate your mucus membranes, which then produce more of the stuff that clogs.
