Get Your Trim Right . Often, divers carry the right amount of weight but in the wrong place. A drysuit diver needs to carry the best part of his weight in such a manner that his chest will come up slightly and his feet go down. Consider where the fulcrum or pivoting point of your body will be. Integrated weight pockets on a BC might be too high up on a long-legged diver. A weight harness allows weights to be slung lower. On the other hand, a diver wearing a lightweight suit and using an aluminium tank might need to add some weight higher up and, if the BC in use has no trim-weight pockets, you can always add a couple of kilos to the camband that goes round the tank. You need to be comfortably horizontal in the water without any tendency to invert. Deploy a Delayed Surface-Marker Buoy Easily in Mid-water. Why do so many divers make a mess of this? Is it because they haven’t been shown how to do it? Carrying a big camera? Learn how to do it easily with one free hand. Stream the buoy so that it floats above you. A tiny bit of exhaled air in it will help keep it up. Pull off as many metres of line that is practical, so that your reel hangs below you. Take the open end of the buoy and hold it with fingers and thumb above the upper side of the exhaust-T of your regulator while holding your head a little to one side. Have the line passing through but not gripped by your hand. Exhale into the buoy. It will start to ascend. Exhale again immediately releasing your grip on the buoy and grab the reel as it gets pulled up to your hand. Release the line from the ratchet of the reel. Watch the buoy go. Tighten off the ratchet as soon as the line loses its tension because the buoy will have reached the surface. Get Your Weight Right. The human body is more or less neutrally buoyant. Take a big breath and your float. Empty your lungs and your heavy head will go under. If we didn’t wear buoyant kit such as our suits, we wouldn’t need to wear weights. If you want to get your weight right, exhale hard at the surface and the weight of your head in the air should push you down. Add an extra amount of lead to compensate for the weight of the gas you might exhale out into the water during the dive and you’re perfectly weighted. So why do so many divers wear too much weight? Is it because they are used to plummeting to the seabed and trampling around before putting air into their BC of suit to make it back to the surface? Neutral buoyancy is the very essence of pleasurable diving. If you are neutrally buoyant near the surface in your drysuit, you will only need to add sufficient air during the dive to make up for the compression of the air that was in it when you started. If you need to put air in your BC too, there’s a good chance you’ve overdone it with the amount of lead you are carrying. Use Your Lung Volume. Don’t keep fiddling with your BC direct-feed inflation. If you are using conventional open-circuit scuba, varying your lung volume can be a useful adjustment when heading over or under obstacles. A big deep breath will stop you from crashing down lower than you intended and using the range at the other end of the lung-volumes you have available will enable you to cruise over things without inadvertently heading for the surface. You’ll soon find that you can do this almost unconsciously and it’s a great way enjoy a relaxed dive. You’ll also find it helps to keep station at a blue water safety stop. Wear a Suit That Fits. When someone asked me which was my favourite diving suit, I replied it was the one that fitted me best. If your drysuit fits your perfectly, there will be less of a drag when you are swimming. If your wetsuit or semi-dry is too big, cold water will flush around it under the arms and around the groin so that you’ll soon feel cold. If your drysuit is too small you either won’t be able to sit down in it or you’ll be limited to the choice of the undergarment you can wear with it. If your wetsuit or semi-dry is too small, it might interfere with your ability to breathe. Try a suit on before you buy it. That's what the changing rooms at Ocean Leisure are for!
