Smith River, Slant Bridge, July 21

Come on out to the Smith River this weekend and dive with us! Temps are way up, viz is great, and flows are down.

 

We’re going to have at least four Rogue Aquatics pros there to lead divers who haven’t dived this site before. Maximum depth is 50 feet and it’s a beginner-level dive (no way you can get lost).

 

Some of us will be there to help out by 8AM, but take your time!

 

It’s an easy drive out 199 to just a mile and a half shy of Hiouchi — for directions and photos of the drive, see these directions or the local dive sites page (scroll down to “Slant Bridge.”)

 

Call us for more info, to rent gear, or to carpool!

Blood Drive – Blood Donation and Diving

Today the Red Cross Bloodmobile is at our shop! Many of the staff donated. I personally found the volunteers very engaging (thanks, Theresa!), and I feel good. Here are some musings by Dr. Ernest Campbell, a great guy who maintains a great online resource, scuba-doc.com

 

“The donor’s body replenishes the fluid lost from donation in 24 hours. If not anemic (Hgb<12 Gm/dl) a person can dive in 24 hours after blood donation. It may take up to two months to replace the lost red blood cells. Whole blood can be donated once every eight weeks. The most important part of the blood to the diver is the red blood cell, responsible for the transport of oxygen to the tissues. The fluid part of blood is replenished in about one day. If the diver waits 24 hours and has a normal hematocrit, then diving should be allowed.”

 

“Red blood cells are perhaps the most recognizable component of whole blood. Red blood cells contain hemoglobin, a complex iron-containing protein that carries oxygen throughout the body and gives blood its red color. The percentage of blood volume composed of red blood cells is called the “hematocrit.” The average hematocrit in an adult male is 47 percent. There are about one billion red blood cells in two to three drops of blood, and, for every 600 red blood cells, there are about 40 platelets and one white cell. Manufactured in the bone marrow, red blood cells are continuously being produced and broken down. They live for approximately 120 days in the circulatory system and are eventually removed by the spleen.”

Dive Guide Course

This May and June, Rogue Aquatics will conduct a Dive Guide Course. Dive Guide is the first of SSI’s professional ratings. As a dive guide you are authorized to lead other divers on dives, including deep, night, and wreck dives.

 

Dive Guide is a leadership position, not a teaching position—the divers you lead must already be certified. The one exception to this rule is Snorkeling, which you can qualify to teach during our course. Dive Guide is a prerequisite to the DiveMaster, DiveCon, and Instructor courses.

 

This course will start in early May, meeting once a week (day to be determined) in May
and June. Bryan Saint Germain will lead the course, with assistance from other Rogue Aquatics staff. If you’re interested, ask us for more information!

Lost Creek Lake, March 2013

We’re still using our old standby, Lost Creek Lake, for those hardy students who want to complete their training before heading to warmer climes.

 

Today was very nice, sunny, no wind. Water cold, of course, 45F, and visibility nothing to brag on.

 

But three of our newest divers (shown here) got it done and are heading out to do some real reef-cruising, critter-watching, warm-water lazy diving! Kudos again to you all for completing the course locally!

Gauge Readers are Back!

Bryan Here . . .

 

I’ve used the Aqua Optics press-in gauge readers for a decade. These are plastic and adhere on their own to the inside of your mask, allowing you to read your gauges (or other things) with your mask on. If you’re anywhere near my age, you know what I’m talking about.

 

Last year the company stopped producing these lenses. But they’ve now released an improved version! These are glass, not plastic, and they glue in to your mask. (Easy to remove, though, as the glue will dissolve in hot water!)

 

Our shop has them in stock now, and at $36 they’re one-quarter to one-tenth the cost of having custom lenses bonded (permanently) to your mask. As I mentioned, you can remove them any time. They come in a range of reader ratings (1.0, 1.5, 2.0, 2.5, and 3.0).

 

The 1.5 are great for me although I need at least 1.75 on land. If you have a glasses prescription the lower “add power” factor is your reader power.

 

Diving Squaw Lake

This has become something of a regular event this Fall. Not an outing for a WWW (warm-water-weenie) but a rewarding adventure nonetheless.

 

This past Sunday (Dec 2) we had the place absolutely to ourselves. Water was clear enough, but increasingly dark and cold as we descended. One dive only, to ninety feet, half an hour of bottom time, temperature at depth just above forty.

 

Definitely drysuit territory, if you want to make more than one dive a day.

Lake of the Woods

Diving today, finding conditions not bad at all.

Water temp 50, visibility good (20 feet?), the roads are clear and no snow in sight.

The marina store is open Fri / Sat / Sun only.

We’ll be back there this coming weekend with OWD students, unless flows on the Illinois drop significantly.
