A Surface Marker Buoy, also known as an SMB or safety sausage is an essential piece of kit for the safety conscious diver.

There are several types of surface marker buoys on the market including the open ended and self-sealing.  Scuba Cat has for several years, stocked a range from the Company “Surface Marker”. Udo Hartig, a diver himself, for optimum visibility, durability and ease of use, has designed this particular range.  It is a range that has proved popular amongst professionals and recreational divers.

An SMB is highly recommended in areas where there is boat traffic. The deployment signals to the boat Captain that there are divers completing a safety stop (5metres for 3 minutes) and are about to surface.  Deployment will also aid divers as it can be used as a reference to maintain the correct depth whilst on the safety stop.  An SMB is also essential when drift diving as it enables the boat crew to track the divers in a current.  Should the diver surface away from the boat the use of an SMB will minimize the wait on the surface, particularly in poor conditions such as high waves and poor light conditions. After all, it is so much easier to see a brightly coloured SMB at distance as opposed to a small head in a large ocean!!

Surface Marker have produced two open ended SMB’s that are compact and come complete with a carry pouch that can easily be attached to the BCD. The SMB’s are made from very durable 210D Nylon and are dual coloured, orange one side and neon yellow on the other. This is the best colour combination for a recreational diver. The orange is bright in strong sunlight and significant glare, whereas the neon yellow is excellent for diminishing light conditions. They also have “Diver Below” written in bold letters. The open-ended SMB’s come in two sizes 145cm and 175cm. The latter is a deluxe model and also has a reflective strip, which increases the visibility of the diver.

The one component that sets these buoys apart from other products on the market is the innovative Webbing Deployment System in also known as WDS. This system is simple to use and minimizes risk of entanglement, which is common when SMB’s are used with string. The webbing system folds neatly and is secured with a small bungee cord. As the SMB goes to the surface the webbing unravels easily and it can be effortlessly gathered on ascent.  This particular system eliminates the use of a reel, which can be daunting for some divers. It is definitely a simplistic system that is proven to work. The ideal depth to release the SMB is at 5.5m, which is ideal for the safety stop. The diver can easily maintain contact with the webbing by using the stainless steel thumb ring. This can easily be released should the need arise.

The Surface Marker Pro is a self-sealing SMB, which is commonly used by professionals and technical divers. These buoys are designed to be inflated at depth. The self-sealing internal baffle ensures that the SMB remains fully inflated on the surface. Self-sealing SMBs are fitted with an over pressure release valve, which allows expanding air to escape as it ascends. This particular SMB comes in three colour combinations that cover all requirements. Technical divers on ascent and decompression stops normally use the orange. This colour signifies that all is well. However, should a problem arise then a technical diver will deploy neon yellow which indicates to the surface support that a problem has arisen and that maybe immediate assistance is required. It is also possible to attach a diver’s slate to the SMB, so communication with the surface is possible.   Instructors tend to favour the dual coloured SMB, which offers optimum visibility in all surface conditions. The range of self sealing SMBs are also furnished with the highly visible SOLAS tape and an attachment for strobes or a cyalume stick.

It is possible to encounter problems when deploying an SMB.  One problem that may arise is a jamming reel when using a self-sealing SMB, which does not have the WDS system.  It helps to have a simple reel or use a finger reel that will not jam.  Surface Marker has finger reels available that will fit snugly into the carry pouch of the SMB, which reduces the bulk of equipment.  The finger reels come complete with 30m of line, a stainless steel double ended snap hook and a thermoplastic spool for durability. When using any reel system be mindful of the possibility of entanglement and do not attach the reel to diver. If the SMB is dragged for any reason and you are attached then a rapid ascent may result.

"Finger Spool"

When inflating the SMB it is recommended to keep your regulator in your mouth at all times. If you use the primary air source and problems enfold then it is difficult to resolve them. It is important to remain calm and in control. When inflating the SMB it is advisable to use one of two methods. Firstly, the alternative air source can be held under the open end of the buoy and air can be purged inside. However, be mindful that in cold conditions this may result in a free flow. The second method of inflation is open the buoy above the primary demand valve and exhale allowing the air to enter the SMB.

"Thank you"

Surface Marker also supply 25kg and 65kg lift bags. Scuba Cat has been loaned several by Surface Marker for use on the clean-up events that are held at least bi-annually. The main events are Earth Day and International Clean-Up. The latter event is a extended to a weekend accommodating participants on one of the two liveaboards, MV Scuba Cat and MV Scuba Adventure.  The loan of the lift bags has proved invaluable over the years for lifting various objects varying in size. They are also ideal for marking objects that need lifting on subsequent dives. The lift bags are available in orange and neon yellow and are made from the very durable 210D Nylon, the same material as the SMB’s. The bags are furnished with a top handle and dump valve, which allows the diver to make a controlled ascent rate when surfacing. They also have a strong stainless steel ring for attaching rope. The self-sealing system ensures that the lift bag will remain inflated on the surface.

One of the latest products is the signal mirror. This is compact and can easily be slipped into a BCD pocket. Should you find yourself in the daunting position of not being seen by a boat the mirror comes into it’s own. The unique feature of the mirror is that it can be directed at a specific target and can be visible for 32km!!!!! You could even signal to a passing aircraft…

"Signal Mirror"

Signalling devices are a must. If you would like to become more confident deploying an SMB then why not do the Distinctive SMB Deployment Speciality or The Drift Diver Speciality.

Search and Recovery is the ideal Speciality if you would like to learn how to use lift bags.

Congratulations…… you have just completed your Advanced Open Water Course.

So how do you show this to Dive Centres around the world?

Your certification card is proof that you’ve successfully completed your training. This will arrive through the Post system to your home address. Once you have the card you are ready to start diving.

If you’re like most divers, you never miss an opportunity to go scuba diving.

If you loose the card, what can you do?

• Replace the card
• Contact Scuba Cat and ask them to do a Check for you then continue your education and get a new certification as a result!

You may also want to replace your card if:

• You damage it .
• You changed your name. (You’ll need a copy of legal documentation of name change.)
• You are upgrading from any Junior Diver certification.
• You would like to replace your existing card with a new Project AWARE Edition Certification Card.

• You want to collect fun limited edition certification cards!

You can easy replace your card online at .com. It will be with you in about 3 weeks. You can also print a temporary card if you cant wait that long.

It’s a little bit harder to change your name, contact first and let them have an email showing the legal documentation. They will change your name on their system; you can then order the new card online. Sound like too much admin? Again why not take the next course?

The future is coming….

As with everything else this small card is going electronic.

The eCard uses the power of the smartphone (initially available for Apple, and Android smartphones) and will be hosted, managed and displayed using the Application.

The eCard will be proof of certification.
Security of the eCard was one of s primary concerns, so QR coding (a specific, two-dimensional code) is integrated to make authentication straightforward and easy.

The eCard will be available for new certifications and replacement cards starting in fourth quarter 2011.

Divers will have the options of a eCard, plastic certification card or both.

We first had the opportunity to try out the Scuba Cat fleet when we went out on a Day Cruise on Scuba Fun to Racha Noi back in 2005.  My Wife, Amy and myself, Carl McKay were on a larger family vacation and we were all aboard, some certifying, some diving in what was our first visit to Phuket. We feel in love with Phuket, the water, the people.

"Scuba Fun"

We have been back almost every year since.

……..Second trip to Scuba Cat

Our family had encouraged us, to move up to the next level of diving:  A live-a-board.  A what-a-who?  Hadn’t done that before and after an explanation of the location at the Similan Islands, the boat and what we could see, we went for it.

"MV Scuba Cat"

The first trip was three diving days.  We arrived from Scuba Sport, the transfer boat, to the remote Scuba Cat Boat.  We didn’t know what to expect.  Surprise was our first expression.  Out in the middle of this clear blue water, we find some islands, a few boats and this mobile diving “experience” – I think you have to look at Scuba Cat, not only as a dive boat, but a place that you quickly connect with new faces that work on board and other guests who are there for the same reason.  It’s like going to a convention and finally everyone has a story to share, because you simply showed up and attended.

"Ready to Dive"

I think what made the experience so nice was how easy the diving became.  Setup in the back of what I think is one of the best ever designed platforms, wide open where easily four people can enter at the same time safely.  The crews at the back are able to help and quickly learn everyone’s needs and are always looking out for you.  They wash your gear off after every dive and clean up for the night too.  Easily you can do five dives in a day!

"........Splash!"

The Dive Masters, are comforting, knowledgeable and don’t stray from the manual; safety was always first.  The orientations prior to every dive spot on.

My Wife was in a peculiar position.  Unlike me, I was up for every dive.  She is safety conscious and honestly does a great check every time.  No shortcuts.  I was a Husband who wanted to have her on every dive.  What I needed to learn was that by doing that put her in a rushed mode and her comfort zone was being tampered with.  I just love doing stuff with her.

"Amy, Andy and Kate"

This is where Sarah came in and became Amy’s most trusted Dive Buddy and now a dear friend.  At that time, Sarah was on board as a Divemaster, now she’s the Queen of the fleet.

"Amy"

As mentioned earlier, Amy is safety conscious.  She likes to drop down when she is ready.  Diving shouldn’t be stressful as it is a vacation and why bother if you are worried.

I would go off with the rest of the family, Amy, still not too many dives in, was guided by Sarah. The perfect combination; Sarah’s experience and understand built confidence in Amy’s skills.  In a nutshell, they would usually jump in last and take their time.

"The Family"

Amy has since moved towards Advanced.  In addition, while most folks don’t care for night diving, within the first two days Sarah and Amy were down at night!  It blew me away.

Something that weighed heavily in building that trust was when Sarah approached us both to discuss an issue with Amy.  She was moving towards Advanced certification with the additional dives she as doing and taking tests on board Scuba Cat.  Sarah said that she didn’t want to move Amy towards Advanced, but offered an Adventure certification.  Simple put, given Amy’s regularity with diving and her comfort, she didn’t want to put Amy in a situation with another Dive Company somewhere out there and their expectations be a burden to her and put her at risk.  It allowed her to learn, move forward with skills and build confidence, but not rushed.

There are a lot of outfits that push you to move quickly through the certification because it makes revenue, I’ve seen some real bad skills and people call them selves Advanced.  Example:  No touchie, just lookie…  Yes, “Advanced” folks touching! NO!

I know that strays from the intent of this entry, but I am trying to show the consciousness of the now owner and integrity over selling another certification.

Diving is a great sport, opens travel to a whole other world, but like in any other sport you need to know your comfort level.  The addition of water isn’t to be scared of, it needs to be respected on every dive.  Experience isn’t the only factor, relearning and doing every check is important too.

Back to the “Cat” – Every Divemaster has been great, the food, amazing and the deck crew always smiling.  By the way, a reminder, if someone is taking extra care of you, it’s good to remember them when they are saying bye to you.  These folks work hard and are another fail safe in an experience on any boat.

"Island 8"

We have been out to the Similan Islands five times now.  Every moment leading up to the transfer boat and the first glimpse of Scuba cat are Exciting.  Meeting new people, bumping into old friends, and sharing new stories.  The tough part is leaving.  A magical experience;  There may be other boats, but Scuba Cat was one of the first.  We just wish it were closer to get to…  I always say “Bye for now” then I know I will be coming back to visit and see great people soon too.

Similan National Park

The Similan Islands National Park is world famous for white sandy beaches, clear blue waters, beautiful sunsets and amazing huge boulder formations. Here you will find some of the most amazing natural scenery Thailand had to offer.

"Donald Duck Bay"

They are easily the best dive sites Thailand has to offer and very rank high in must visit list of Dive Sites in the world.

MV Scuba Cat Live aboard cruises around these Islands for 6 months of the year allowing divers of any level and snorkelers to take in this amazing beauty in one of the most relaxed atmospheres of all liveaboards in the Similans. She has a unique liveaboard schedule allowing a stay from 2 days 1 night, with a maximum of 20 customers staying on board. We are proud to have so many customers who come back to us year after year – I am sure you will agree after a trip on board.

"The Cat"

Rob Fraser-Thomson is one of our many repeat customers’ with Scuba Cat Diving.

“I started diving in Thailand in 1999 whilst doing my IDC with a company based in Kata. It wasn’t for another 2 years that I returned to Phuket after working in Italy. I had heard good things about a company called “Scuba Cat Diving”, during the IDC from other students and other divers, so decided to book my trip with them.

The MV Scuba Cat is based in Simians during the high season, a spectacular group of islands north west of Phuket. Unlike other liveaboards, the boat is permanently based in the islands, customers are carried to the liveaboard via minibus and speedboat, the Similans are a long way from the mainland so this saves much time. You can be diving within 30 minutes of arriving on the boat, after the boat and dive briefing off course.

I have heard people mention that the transfer takes a long time but most the other dive companies take longer to sail from the mainland, the Similans are far out to sea and a world-class dive site.

During the low season the MV SCUBA CAT is based at Racha Yai, a group off islands south of Phuket, it is usually quieter at this time of the year but the diving is just as good. If you have a good eye, this area is rich in the smaller species you don’t spot in the Similans.

"The View during low season"

Captain Min and his crew are always a bonus being very helpful to new divers on the boat and the old ones! The dive guides are very competent and professional, the only problem I have ever had was with triggerfish.

I still try to do 2 trips a year on the MV Scuba Cat, both to the Similans and Racha Yai. Although I have been on MV Scuba Fun day trips and MV Scuba Adventure, I prefer the MV Scuba Cat with its large dive deck and open plan design.

10 trips and 500 dives later, having seen many other companies and their boats, Scuba Cat is the only company who I would book with and I have no intention of changing.”

5 days and counting……………………See you again next week

It is almost guaranteed that when you dive on coral reef from Phuket, Thailand  you will encounter the vibrant coloured Parrotfish.

"Hello"

Parrotfish are abundant and range in size from 30cm to 1.4m. How did this family of fish (Scaridae) derive the name Parrot?  Just have a look at the dentition; numerous teeth are fused to form a beak, much like a parrot’s beak. The teeth aid feeding activity as the Parrotfish eats algae from coral and rocky substrates, often leaving teeth scars behind. Parrot fish are considered to be herbivores, but they are not necessarily vegetarians as the large Green hump head parrot fish is known to include coral polyps in it’s diet.  The feeding activity of the parrotfish is important in the production and distribution of coral sands. If you watch Parrot fish excrete you will notice that it is fine white sand. This has been responsible for helping create small islands and beaches worldwide. It is estimated that a Parrotfish is capable of producing 90kg of sand per year!!! How is this possible? The beak takes the coral or rock and then it is pulverised by a set of grinding teeth located in front of the oesophagus. The digestion procedure gives sand as the end product. The Parrotfish eating habits are paramount in controlling algae growth resulting in a thriving reef. Another little fact about the Parrotfish is that their teeth continuously grow and by chomping on rock keeps the growth in check!!

"Parrotfish"

Parrotfish are known to reproduce throughout the year, but more predominantly during the summer months. This family are generally sequential hermaphrodites starting their life as female then change to male. However, one exception to this is the Marbled Parrot fish, which is known not to change sex.  Parrotfish are pelagic spawner’s. This means that the eggs are spawned in mid water and are buoyant, the eggs float freely eventually resting on the coral where they stay until they hatch. The Parrotfish larvae appear not to have any characteristic facial features or colouration for the first few days after hatching.

Juveniles have a different colour pattern to the adults and it is possible for juveniles of some tropical species are capable of changing colour temporarily to mimic other species. It is not unusual to see “flocks” of juveniles swimming en mass over a coral reef. Often they are dark in colour and occasionally an individual can be seen changing it’s pigmentation.

The Parrotfish are unique in that they are able to secrete a mucus cocoon from a gland near the mouth. This provides protection from nocturnal predators. Also, it can act as an early warning system allowing the fish to flee if the protective cocoon is disturbed. The Parrotfish is only able to produce this cocoon once during the night, so it is important when night diving not to disturb the sleeping Parrot fish.

The Parrotfish skin is covered in a mucus substance that is believed to have antioxidant properties that can help repair any damage that may occur to the skin. Also, the mucus has anti parasitic properties, repelling potential parasites.

There are approximately 80 identified species of Parrot fish, which are abundant in and around coral reefs worldwide. They are a close relative to the Wrasse family, but there are some distinctive features that help with identification. When trying to identify a parrotfish look for an elongated, blunt head. The body of the fish is deep and brightly coloured with defined large scales and finally look for the unique bird like beak.
