Tips for… Using an SMB



Ok, so not the most exciting of topics… but an important one nonetheless. Especially as many of us will be getting ready for the UK dive season and heading out to explore our beautiful coastline. Some of you may even be heading into the UK waters for the first time due to the travel restrictions… welcome, you will wish that you had done it sooner!

Surface marker buoys. SMB’s are an invaluable piece of equipment – to demonstrate your position in the water, to fend off boats, to show off your buoyancy to your dive buddy when you can inflate it without moving an inch in the water… or to unintentionally make your buddy laugh when you forget to attach your reel and send it up like a lost rocket! Using an SMB is a must-have skill and piece of equipment for all divers. But, how do you choose which one is right for you, and how do you use it correctly?

Choosing a colour – we all know to look cool as a diver is all about co-ordinating, but not so much with SMB’s I’m afraid. The standard colour is orange and is what you will typically see being used. Yellow due to its higher ability to be seen at night time is just for an emergency… not because it is your favourite colour… sorry, yellow lovers! If you are wanting to personalise it though you could put your name down the SMB, that way the surface cover knows who it is underneath.

Next, inflation. Here we have the option of open bottom or direct inflation. An open bottom means that you will need to use your alternate to inflate the SMB, direct inflation you would use your inflator hose. Either of these are sufficient and it’s generally down to preference. If you are not sure which you prefer, or how to use them, there is a course that you can take to learn all of the skills which offers some helpful tips on how to inflate it and control your buoyancy too. I happen to know an instructor that teaches it… so just drop me a message and I can help!

So, we have the SMB, next we need a line or spool. So many decisions with a basic piece of kit! Most SMB’s will come with a line, which is great as you can use the equipment straight away. The only downside is that with gloves it can become annoying, especially if you are changing depths quite often as is typical on a shore dive here. So, you may wish to look at a spool instead. They also come in more colours, and this time you can choose whichever you want… even yellow, result!

Having got to the point of choosing your SMB and line/spool, where are we now going to keep it? Clipping it onto your BCD; keeping it in your pocket. Anywhere is sufficient as long as it’s easily accessible… like not in your car once you have entered the water! So be sure to add your SMB to your buddy check! Happy diving!

BSAC launches Divesoft Liberty rebreather course



The British Sub-Aqua Club (BSAC) is bolstering access to technical dive training with the new BSAC Divesoft Liberty CCR course.

This course is a first step (MOD 1) into the silent bubble-free world of rebreather diving, and opens up a new world of diving experiences and possibilities for members.

Benefits of the Divesoft Liberty rebreather

Founded in 2013 in the Czech Republic, Divesoft developed its closed circuit rebreather (CCR) primarily with the guidance of cave divers. The Divesoft Liberty was the first fault-tolerant electronically controlled rebreather released into the recreational diving market. The Liberty is designed where all vital electronic elements have redundancy so that no single failure can disable the system.

Even if a critical systems error occured, the diver can safely return to the surface on the Liberty, maximising safety and efficiency. The design follows the same approach utilised in many safety-critical applications in the aerospace industry.

The Liberty’s modularity and ease of maintenance allow the diver to maintain the unit in all environments, including the harsh conditions of an expedition.

Divesoft Liberty rebreather

BSAC Divesoft Liberty CCR Diver course

The brand new BSAC Liberty CCR course will teach a suitably qualified open-circuit diver to safely dive their rebreather to a maximum depth of 45m. This highly versatile unit offers a wide range of adjustability and settings, making it great for beginners and expert CCR divers alike.

Students get a thorough grounding in rebreather technology, and in-depth Liberty-specific training. The course includes decompression diving, and trimix gas planning, and teaches all the skills and drills required to dive the Liberty and address all possible situations.

The course is open to BSAC Sports Divers or above, who have completed a 35m depth certification. Trainees must also hold the Accelerated Decompression Procedures qualification or be an Advanced Nitrox diver (or equivalent.)

Divesoft Liberty rebreather

The BSAC Liberty course covers decompression diving and trimix gas planning, with skills and drills required to dive the Liberty and address all  possible situations. Trainees can choose to dive with air as a diluent, but will have been trained using 20/35 trimix as a diluent,  so when they use 20/35 are allowed to dive to a  maximum depth of 45m, at the MOD 1 level of training.

The dry practical sessions will cover assembly, preparing and maintaining the Liberty, including updating the control firmware and downloading dives from the unit, using the Divesoft PC and phone applications.

All the new skills will be introduced during the sheltered water training dives, including applying the student’s current rescue skills to CCR diving: the sheltered water training is followed by seven open-water dives.

Nick Jewson, BSAC Technical Liberty Instructor said:

“The introduction of the Liberty CCR MOD 1 course demonstrates that BSAC continues to evolve its technical dive offering for members. We plan to have a minimum of four BSAC Liberty instructors in place early in the 2024 season, and with potential students waiting to do the course we can’t wait to see BSAC-qualified Liberty divers using this impressive rebreather in exciting expeditions very soon.”

Divesoft Liberty rebreather

The BSAC Liberty CCR MOD 1 course will be officially launched at the Go Diving Show near Kenilworth, Warwickshire on the weekend of 2nd-3rd March 2024, where Divesoft will have units on display.

Nick continued: “Visitors should head to stand N4 to get a hands-on look at the Divesoft Liberty and talk to the BSAC Liberty course team. Come and have a look, book your place on a regional Liberty try dive event, or sign up for the BSAC MOD 1 Liberty CCR Diver training course. We’ll ready to show you how the Liberty CCR can transform your diving!”
