Travel ready with everything you need for professional quality UW pictures
SeaLife has created the ultimate digital dive camera system which includes all the popular accessories and a 2GB memory card. The SeaLife DC 1000 Maxx is outfitted with the DC1000 camera, wide angle lens and two Digital Pro Flashes in a deluxe hard travel case. Dual flashes eliminate shadows by illuminating the subject from both sides. Light up the deep and capture spectacular underwater images with the brightest colors you ever imagined.
Set the camera to Ext Flash Auto mode for automatic exposure control with the Digital Pro Flash, resulting in vibrant colors and reduced backscatter. The Ext Flash Manual mode offers advanced UW photographers manual aperture and shutter speed controls.
Quick shutter response for fast action photography. Long lasting lithium battery for all day of diving. Automatic focus from 2" to infinity. Large format continuous video recording with sound. Depth tested to 200ft.�
With the Sealife DC1000 Maxx Kit you can take photographs as you explore the ocean world both above and below the water. This easy to use 10.0 Mega-pixel camera is good to depths of up to 200′ (60 m). Of course it is also ideal for taking worry-free pictures in the rain, at the beach, or on the ski slopes.
The camera features a large 2.7" LCD screen. This allows precise framing underwater. When shooting underwater without flash the camera has 4 underwater white balance settings. One is for blue ocean water less than 25′ (8m). The second is for blue ocean water deeper than 25′ (8m). The third is for green water less than 25′ (8m)and the last for green water deeper than 25′ (8m) . With the Spy mode feature you can set the camera to automatically take photos in ten second, thirty second, one minute, or five minute intervals. By setting this up on a tripod and swimming away you can photograph very shy creatures.
The camera housing allows access to all camera functions underwater. The sure fire flash connection system holds your fiber optic cable in the perfect position so the flash will fire every time. The camera is part of a system that will nurture your creativity and allow expansion of your underwater photography skills.
The kit includes two Sealife SL961 external strobe. Dual strobes eliminate shadows by illuminating the subject from both sides. Since water absorbs the red and yellow light spectrum resulting in blue pictures, you need a flash to bring out the intense colors of the underwater world. It also reduces the backscatter problem that normally will occur when using a camera with a built-in flash.
When using the Auto Mode Setting, the strobe automatically adjusts the brightness for optimal image exposure. You can also shoot in manual mode. The strobe features variable flash control enabling you to dial the flash power up or down for better image exposure. Also included is a flexible, rubberized arm for easy aiming and a sure grip. This will allow you to position the flash for the best possible lighting.
One of the most important secrets to quality underwater photography is to to be as close to your subject as possible. For large subjects the included Sealife Wide-Angle Lens is extremely important. It will increase your field of view by 50%. You will be able to capture that 5′ shark from 5′ away or fit a group of divers into one frame. You can get as close as 12" to your subject to insure bright colorful pictures.
The Sealife DC1000 arrived from K2Scuba.com earlier than promised. It comes assembled and in a very sturdy travel case. Instructions are clear and the system is easy to operate. It helps to be aware of several differences between typical and underwater photography before you use the camera and strobes. (Sealife on-line info is a good starting place for the uninitiated.) I took the system on a trip to the Carribean for a week of diving and was delighted with the quality of the system! The U/W housings are excellent and durable. The video quality is super and you can switch between still shots and video underwater by simply changing a setting. The screen size is quite adequate. Overall, a great buy for a system used by a recreational diver. Linda Marie from Wisconsin

an anonymous and customer review of the Pinnacle Evolution 2 from Divers One
Just wanted to share my thoughts on my new drysuit, the Pinnacle Evolution 2 for anyone who was looking to buy one or was shopping around for a dry suit–
Diving the cold California waters last winter make me break down and get a drysuit–the ol’ 7mm wasn’t cutting it for Multiple daily dives
I am 6 feet tall and tip the scales at a lean 155lbs, and went with a size ML as said on the Pinnacle website. As far as options, I went with the neoprene socks (size 11, same as my regular shoe size) and they are a perfect fit. The rock boots are a size larger at 12. I also had a P-Valve installed. The suit comes with a 7mm hood, hose, suspenders, and storage bag. I also ordered the Pinnacle Evolution undergarment, size Large. Total time from order to delivery was less than 2 weeks. 
First, what I don’t like/would change…
Overall, the fit is very good. There is some extra material around the calf that creates some air space, but this might be because of my lean (skinny) legs/build. The extra space did not cause too much of a problem during my first couple of dives, but I want to try it with gaiters to see if it makes a difference. The suit is very stiff when dry, but loosens up nicely when underwater.
The Evo 2 does come with pockets–which are pretty small but functional. I was able to fit a backup light in one pocket and an SMB in the other. Larger pockets would have been nice, but I don’t carry too much gear, so it shouldn’t be too much of an issue. The Suit is not as form fitting as say the whites fusion, and you can definitely feel the extra drag and effort it takes to push through the water.
The stock pinnacle rock boots are very narrow, so if you have wide feet, you might want to try a different style of rock boot.
The wrist seals are thick latex which is good, but where they attach to the suit is a bit bulky, so adding gauges (wrist computer, compass, slate) takes some care/repositioning and effort.
The SI p-valve sticks out. it is not in the way, but it is not as low profile as some of the other models out there.
Now, what I like:
The Evo 2 is definitely a rugged suit-the cordura looks like it can stand up to a lot. it looks tough, and although I tend to baby my gear, it can hold up to some scrapes and scuffs. The wrist seals are very heavy latex–heavier than the DUI ones on the suit I was looking at.
The front entry, Telescoping torso, and ample space in the torso make it a breeze to put on and take off. In the water, the suit becomes much more flexible, making putting fins on, venting air etc an easy task.
From my experience, the Pinnacle size chart is a good measure of size/fit.
The Pinnacle Evo undergarment is VERY warm. it is a bit buoyant so extra lead might be in order, but for California diving it fits the bill. The moisture wicking aspect of the undergarment does its job perfectly.
The rock boots, while narrow, have laces that go far up the ankle, giving a good amount of support and security from feeling the air rush to your feet.
Bottom Line:
I am very happy with this suit. It has all the features/options I was looking for (pockets, front entry, warm neck collar, p-valve, relief zipper, vulcanized boots or neoprene socks, etc) and for the price, is a great deal. I was able to get the Suit, Undergarment, Rock Boots and Accessories for a lot less than a stock DUI TLS350. If you are in the market for a drysuit, give pinnacle a try. As I get more dives in this suit I’m sure I will have some more to say.

About 20,300 Halcyon diving equipment product OPV’s, made in the U.S. by Halcyon Manufacturing Inc., of High Springs, Fla., are being recalled because they pose a drowning hazard for divers. The over-pressure valves in the diving equipment could fail, allowing the buoyancy compensator devices and the diver lift inflatable devices to leak. No incidents or injuries have been reported.
From the Halcyon Website:
Halcyon OPV Spring Recall Information – VIDEO presentation
The highest priorities of Halcyon Manufacturing are the quality of our products and the safety of our customers. We are posting this information you to provide details regarding the voluntary recall of select Overpressure Relief Valve (OPV) Springs.
Halcyon Manufacturing Inc. in cooperation with the US Consumer Product Safety Commission has initiated a voluntary recall of select Eclipse, Evolve, Explorer, Pioneer and CCR35 buoyancy compensator’s (BCDs) manufactured between January, 2006 and September, 2008. In addition, select Halcyon inflatable devices (Lift Bags, SMBs, DAMs, Surf Shuttles and Diver Lift rafts) may also be affected.
These BCDs or Inflatable Devices could develop excessive corrosion or rusting problems with the stainless steel Over Pressure Valve (OPV) spring, causing the spring to fail and the BCD or Inflatable Device to leak through the OPV. It is unlikely that most of these units will experience any problems since the potential defect is limited to a very small portion of the total number of OPV springs used during this time period. However, given the potentially serious implications all OPV springs should be checked to minimize risk or inconvenience to Halcyon customers. BCDs manufactured after September, 2008 are not included in this voluntary recall.
Please reference this website information, or visit your local Authorized Halcyon dealer, for details on how to identify the BCD serial number. Inflatable Devices do not have serial numbers and should be checked based on customer purchase date if possible. If there is any doubt as to the serial number or date of purchase, Halcyon recommends inspecting the OPV spring at the request of the customer.
Worldwide Halcyon distributors will be initiating a similar inspection and replacement process through their dealer networks. Halcyon Manufacturing, Inc in High Springs Florida will also inspect those BCDs or Inflatables sent directly to our facility, replace the OPV spring if necessary and provide free return shipping to the customer.
We apologize for this inconvenience and encourage Halcyon BCD and Inflatable owners with questions to contact their local Halcyon dealer, regional Halcyon distributor or Halcyon Tech Services directly using the following contact information.

The following steps will assist the customer in identifying the serial number on their Eclipse, Evolve, Explorer, Pioneer or CCR35 buoyancy compensators (BCDs) manufactured between January, 2006 and September, 2008. If you cannot locate a serial number on your BCD please contact us. 
If the serial number begins with the following sequence, the OPV spring in the BCD should be inspected:
61, 62, 63, 64, 65, 66, 67, 68, 69, 6A, 6B, 6C, 71, 72, 73, 74, 75, 76, 77, 78, 79, 7A, 7B, 7C, 81, 82, 83, 84, 85, 86, 87, 88, 89
Video review of affected products
- The OPV on your BC or your inflatable product can be checked by a technician. Please share this information with your technician to ensure no mistakes are made. Also, please refer to the online video at www.halcyon.net/opv-recall-videos for a detailed overview. The OPV cover should be turned counterclockwise until the cap can be removed. To replace the cap after inspection, be sure the threads are set properly by turning slightly counter-clockwise and then turn clockwise until the cap is seated firmly. DO NOT OVERTIGHTEN. It is possible to damage the threads and/or crack the OPV cap.
- After being re-assembled you should verify the integrity of the fitting and the function of the OPV. Pull gently on the OPV string to be sure the spring functions. Pressurize and submerge the wing in water to check for leakage.
- If defective, the spring should be removed and replaced. The new spring should be obtained from a Halcyon Authorized facility and threaded into the pull dump cord.
- If your technical or dealer experience any problems please send the affected product directly to Halcyon for evaluation.
- If there is no serial number on the wing, the wing was manufactured prior to 2004 and is not part of this recall.
- If for any reason the customer believes there may be an issue with an OPV spring but the serial number is missing or outside the range of Serial Numbers given, Halcyon and its Dealer and Distributor Network will also inspect and replace, if necessary at no charge to the customer.
Halcyon Inflatable products are not serialized therefore customers who purchased a Halcyon Inflatable product in 2006, 2007 or 2008 are encouraged to check the inflatable OPV spring.
A non defective OPV spring will look like these. Some discoloration is common. Spring should remain strong, and appear ‘normal’ when dirt or coloration is removed
Detailed video clips to aid in evaluation and replacement can be found here. 
A defective OPV spring will look like this. Note excessive corrosion in the OPV assembly. When scraped off the spring exhibits possible pitting and damage.
To ensure long term functionality of your Halcyon BCD or Inflatable, it is important to thoroughly rinse the BCD or Inflatable post dive including all fabric, plastic and metal components. Please reference your Halcyon BCD Product Manual or access online at: http://www.halcyon.net/manuals
Please contact Halcyon Technical Services with any questions: techservices@halcyon.net
The recalled products were sold at diving equipment retailers and distributors from January 2006 through December 2008.

Can A Shark Stop, Close its Eyes and Rest?
© Megan Jungwi Sep 21, 2009
Shark sleep remains a mystery to scientists, however, important insights have been made.
Although at one time it was commonly thought that all sharks were constantly on the move, it is now well known that many species of sharks will often take a break from constant swimming. However, less understood is a shark’s ability to rest and how shark sleep compares to human sleep.
Signs of Sleep in Sharks and Humans
Humans can easily tell when a friend is falling asleep because of the way he stops moving and closes his eyes, usually at night. Scientists can further study human sleep using an electroencephalogram (EEG) to record brain activity or an electroculogram (EOG) to watch eye movements. In sharks studying sleep is much more difficult. Sharks do not display habits that humans can quickly recognize as sleep and even among sharks different species show different lifestyles and behaviours.
Do Sharks Stop and Close Their Eyelids?
Some species of shark need to constantly move in order to breathe, such as hammerheads and great whites. Other species of shark do stop and sit on the ocean bottom. However it is questionable whether even these motionless sharks are sleeping. If sharks do sleep they don’t close their eyes to do it. According to the San Diego Natural History Museum’s page “Shark School > FAQs”, sharks can’t even blink. Although sharks do have upper and lower eyelids, these don’t close. (Although sometimes a nictitating membrane will move over the eyeball to protect it.) Shark expert and zoologist, R. Aidin Martin at the ReefQuest Center for Shark Research says in “How Do Sharks Swim When Asleep” that these motionless sharks can follow divers with their eyes – suggesting they are not in fact asleep.
Sharks and the Circadian Rhythm
The circadian rhythm is sometimes referred to as the ‘internal clock’ and it regulates a creature’s biology throughout a 24-hour period. For example, a person generally sleeps at night and is active during the day. Studies show that, some sharks at least, do have a circadian rhythm. Larry Glenn Allen et al describe in the book Ecology of marine fishes: California and adjacent waters how the swell shark and horn shark have a nocturnal rhythm. These sharks are active at night and during the day they find rocks to hole up in.
The Shark Brain and Sleep
Sharks that are obligate ram ventilators can never stop moving. However, R. Aidan Martin describes an experiment that may explain how these sharks manage to continuously swim without rest. Studies done on the Spiny Dogfish shark (Squalus acanthius) showed that sharks co-ordinate their swimming movements through a ‘Central Pattern Generator’ in their spinal chord. Since this generator is in the spine and not the brain the shark can continue to swim even while unconscious. R. Aidan Martin also suggests the possibility that parts of the shark’s brain shut down while others continue to run the body – a shark version of sleep walking.

ACID TEST, a film produced by NRDC, was made to raise awareness about the largely unknown problem of ocean acidification, which poses a fundamental challenge to life in the seas and the health of the entire planet. Like global warming, ocean acidification stems from the increase of carbon dioxide in the earth’s atmosphere since the start of the Industrial Revolution.

“How do scuba divers use the laws and principles that describe the behavior of gases to their advantage? What precautions do they take to prevent the bends?”
Bud, that is a great question! The physical laws that you are referring to is Boyle’s Law:
As the video shows, the airspaces in your body are replaced with a commensurate amount of oxygen and nitrogen. We as divers are careful to ongas and offgas the nitrogen (which is 78% of atmospheric air).
The best way of doing this is to ascend slowly. Technical divers do this by doing stops at 70′ then 50’-40’-30’-20’-10 feet of seawater for one minute each. Don’t be fooled your 15′ for three to five minutes IS a decompression stop.
Again, great question, and glad to help.
