Decompression Theory – Part 2

Published

From its humble beginning in 1994 to today, the group of training agencies Scuba Diving International (SDI), Technical Diving International (TDI), and Emergency Response Diving International (ERDI) form one of the largest diving certification agencies in the World – International Training. With 24 Regional Offices servicing more than 100 countries, the company today far exceeds the original vision the founders had when they conceived the idea on a napkin, sitting at a kitchen table in the early 1990’s.

What you need to know about SMBs!

Published

on

Ok, so not the most exciting of topics… but an important one nonetheless. Especially as many of us will be starting to enjoy 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 un-intentionally make your buddy laugh when you forget to attach your reel and send it up like a lost rocket… 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, its 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, and yellow due to it’s 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 is 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 and offer some helpful tips of 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 down side is, with gloves it can become annoying, especially if you are changing depths quite often as typical on a shore dive here. You may wish to look at a spool instead… They also come in more colours, and this time you can choose which ever you want… even yellow, result! 

Having got to the point of choosing you 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 its easily accessible… like not in your car once you have entered the water…. So be sure to add you SMB to your buddy check! Happy diving!
