New Book on Underwater Digital Video

Filed under: Uncategorizedscubadoc @ 10:55 am

Steven Barsky has done it again! I have just received and read through his new “how to” book on underwater digital video. I wish that I had access to this excellent instructional manual some years ago when I ventured into the arena of underwater video during a trip to the Red Sea. I’m certain that my results would have been a lot less amateurish. Now, if he could just write something that would offer assistance with getting through Egyptian customs with a camera - then everything would be perfect. (G)

Underwater Digital Video Made Easy is a book that will take you from beginner through advanced underwater video skills. It is packed with practical, real world information from three underwater video professionals and includes the following chapters:
Camera Selection • Housing Selection • Accessories • Gear Set-Up • Shooting Topside in the Marine Environment • Shooting Underwater • Lighting Underwater • Travel • Maintenance • Editing • and much more!

Most of us don’t want to be a motion picture director but just want to make home videos of our next diving vacation. Well, this book is the place to start! This is the most up-to-date book on the exciting world of underwater video.

In the book there are hints and techniques for underwater video that you won’t find anywhere else. Each chapter includes useful tips based upon actual underwater video or film projects that have been shown in theaters, seen on television, or are available on DVD.

Authors Barsky, Milbrand, and Thurlow are all professional underwater cameramen with a combined total of over 37 years in the field of underwater video production.

In addition, there is the pleasure of seeing their beautiful and talented diving model, Kristine Barsky, the wife of one of the authors.

A sample chapter can be downloaded at this address:

Underwater Digital Video Made Easy, Sug. Retail Price $23.95
192 pages, over 150 photographs and illustrations

Ideal Body Weight for Diving, Scuba Calories

Filed under: Uncategorizedscubadoc @ 11:49 am

In response to a question about diving and obesity - here is an answer giving the ideal body weight for diving:

Edmonds, in the book, Diving and Subaquatic Medicine, states that weight should be less than 20 % above the average ideal weight for age, height and build. Obesity is undesirable because it increases the risk of decompression illness, there being an increase in nitrogen absorption of 4.5 times in fat. Sport diving is more lenient than commercial in this regard in that the bottom times can be reduced according to the percentage that the candidate’s weight exceeds that expected for height and build.

Body mass index (BMI) is a method for determining the percentage of fat. It is determined by weight in Kg divided by height in meters squared.

In some areas of the world where medical fitness is more stringently regulated than the US, a high BMI (body mass index) would deter one from diving. Complicating conditions of adiposity include diabetes mellitus, dyslipidemia or hypertension and their associations with coronary artery disease. The BMI is important to divers due to the fact that people with high BMI are more prone to coronary artery disease and an untoward coronary event while diving. A BMI above 30 kg/m2 is thought to be excessively risky for diving. Of course, measured %BF can sometimes show that the diver is quite large and muscular and this needs to be taken into consideration. Figure your BMI by going to this web site:

In one of our newsletters, reference was made to the approximate number of calories burned while scuba diving. The figures quoted (393 kcal for a person weighing 130 pounds, 413 kcal for 155 pounds, 604 kcal for 190 pounds) were all estimates but seemed inordinately high to some people who felt that scuba diving was essentially a sedate activity in a weightless milieu.

In researching a valid answer to this question we came up with some data that hopefully explains the burning of oxygen - and thus calories (kcal). There are quite a few variables in the equation, such as water temperature, level of fitness of the individual, size and body configuration of the diver, current, surge and buoyancy. Swimming energy is also proportional to the square of the velocity and workloads for higher use are tolerated by only the very fit.

Maximum burning of oxygen in the very fit is 40ml/kg/minute (VO2). Resting VO2 is 3.5ml/kg/min. or 1.5-2 kcal (1 MET). All things being equal, the act of scuba diving at a speed of 1 knot burns about 25 ml/kg/min of O2 (about 60% of maximum), the diver moving about 70 feet per minute. (Bove, ’Diving Medicine’, 1997).

A resting value of 3.5ml/kg/minute interpolated to 25 ml/kg/min is 8 kcals/min. A diver swimming for one hour at this rate would burn 480 calories, depending upon any or all of the variables noted above. See also: Nutrition and Diving

Best regards for safe diving!

Divers Alert Network Joins with World Communications Center To Provide Global Satellite Communication Services to Divers

Filed under: Uncategorizedscubadoc @ 10:09 am

CHANDLER, Ariz. ­ September 27, World Communications Center (WCC), a provider of global satellite voice and data communications, announced today that Divers Alert Network (DAN) has signed an agreement to offer its member divers the ability to rent WCC¹s Iridium satellite phones when diving in remote locations.

Satellite communications provides the ideal solution for divers, who typically travel in areas where landlines and cellular service are not available. In emergency situations, this can be cause for concern.

WCC provides service and equipment for satellite telephones, mobile asset tracking devices and satellite broadband internet. The company offers the one truly global satellite system, Iridium, which provides complete global coverage including all oceans and seas with no long distance or roaming fees. The WCC rental program allows DAN members to rent satellite equipment at weekly rates and pay for minutes they use at a fraction of what most international phone calls cost. User-friendly added-value features can include waterproof phone bags, special one-button programming to contact the DAN and WCC’s 24-hour customer care.

WCC President Sam Romey said that with Iridium’s unique truly global network, WCC has always recognized the value of satellite communications in the diving industry. “Many divers already use WCC¹s services, but our new relationship with DAN will help to reach out to its members and ensure further safety via reliable communications,” Romey said.

Tony Bacci, Vice President of Marketing and New Business Development at DAN, underscored the value of the relationship with WCC. “Thanks to our partnership with WCC, we can offer our divers and group leaders an effective way to communicate back to us in case of emergency,” Bacci said. “We encourage divers to take advantage of this program so they can travel and dive to remote and beautiful places with peace of mind.”

To launch the new DAN/WCC partnership and encourage traveling divers to learn about the easy-to-use Iridium satellite system, introductory specials are available to DAN divers and professionals including discounts, custom programming and other incentives. Details of each offer will be available at the DEMA show in Las Vegas, on the DAN website ( ) and on WCC¹s website (

“Diver’s Day” Meeting, for Local Dive Shop Owners and Managers

Filed under: Uncategorizedscubadoc @ 10:29 am

Dear Local Dive Shop Owners and Managers,

There is still room to attend the “Diver’s Day” Meeting this Saturday, September 24th, 2005, from 8am to 5pm at the Wyndham Hotel in Colorado Springs. This is part of a 2 day meeting of the Pacific Chapter of the Undersea and Hyperbaric Medical Society (UHMS).

I think that you will find the program of value to your divers, divemasters, instructors and almost anyone interested in diving. The Diver’s Alert Network (DAN) usually has a Diver’s Day like this but has not had one in Colorado for several years and we are not sure when they will be back. We put together a similar program that I think you will enjoy.

The cost is $45 (plus $25 if CME credit is needed for MDs, RNs, or CHTs) and this includes Saturday registration and food and beverages at the exhibit and break session. Lunch is not included. Parking is free. Rooms are still available if needed.

We have some excellent world class speakers and it will be a good time to interact with Diving Medical Experts in a friendly small setting.

There are lectures on Friday, September 23rd as well (on Hyperbaric Medicine and Wound Care) and a Banquet on Friday Night with presentations by some world renowned Diving Doctors. You are certainly welcome to these programs as well.

You may want to also forward this email to your clients. We also still have room if you shop wishes to have an exhibit booth on Saturday.

For more information go to and click on the Pacific Chapter UHMS Meeting or go to the other site at

Hope to see you there.
