Need some help?

Here are a few hints and tips that we have been offering to our customers over the past 20 years to help them make the right descision as to either how to put on their wetsuits easier or to what kit to purchase for their specific needs. If you wish to discuss anything in more detail or need more help then please either email or call us.

WETSUITS:- How they work

A wetsuit creates a barrier against the elements using the insulating properties of neoprene. By trapping a layer of water between you and the wetsuit, your body is able to heat the water up and thus keep you warmer. However, the looser the fit the less effective your wetsuit will be as more water will be able to circulate around your body. Your wetsuit should be a snug fit all over but comfortable to wear as well. However, from our experience we find that customers prefer childrens wetsuits to be about one size bigger as:

a) They last longer

b) They are easier to put on.

This last point should be borne in mind if you are considering a childs full wetsuit as small, flexible legs and neoprene do not mix very well! If a wetsuit is a bit loose or you need some more insulation you can always wear a T Shirt, rash vest or thermo vest underneath. Wetsuits come in a range of thicknesses from 0.5mm upwards. As a general rule >1.5mm tend to be for use under a standard wetsuit or for surface sport use abroad. 2mm - 3mm tend to be for summer surface use only. 3mm - 5mm winter surface use or dive suits abroad. 5mm + tend to be dive suits (although we recommend 7mm for UK diving.) The main point to consider is that the thicker the wetsuit the less flexible it will be. All wetsuits also offer some UV protection.

PUTTING ON A WETSUIT:

When putting a wetsuit on you should (seems obvious but as we see in the shop every year its not) remember that underneath you will most likely have your swimming gear on and not your normal clothes. Also if you have sharp finger nails take care as you can tear the neoprene and for the same reason, remove whatches, chunky jewellery etc. First check that the suit is either front zip or back zip then when it’s the right way round put your feet in and pull your suit up to your crotch making sure that the knees are where they are supposed to be and so is the crotch. Next pull the suit up to your chest area before you put your arms in. Once the suit is on and zipped up adjust the arms to suit i.e. pull them up in stages (this will ease the tension across the chest) starting at the wrists.

When removing a wetsuit it is best to pull the suit off inside out, then rinse the suit out with cold water and hang to drip dry. If you do this whilst it's inside out then the inside dries first (its never pleasant to put a wet wetsuit on!) and the sun does not bleach the colours out quite so quick.

DRYSUITS:

A point to remember when you first see a drysuit is that unless it is a neoprene drysuit you will be surprised at how tall the suit is. This is to allow the wearer to bend their legs, move their arms etc as there is no stretch in the material. If it is too tight around the neck, wrist, ankles then some suits allow you to trim 'rings' off the seals to get a more comfortable fit (just don’t overdo it).

Masks:

All our masks have at least a silicone skirt and many a silicone strap along with tempered safety glass lenses. The advantage of silicone is that it retains its flexability for longer and lasts longer than other types of mask skirts like rubber, plastic or silitar. The tempered glass lenses mean that they can withstand the pressure when diving but do not shatter when damaged unlike glass.

A mask should be a comfortable fit. To see if a mask will be watertight put the mask on your face without the use of the strap (making sure that your hair is away from the seal of the mask) and breath in through your nose. If it sucks onto your face and you cannot hear or feel air coming into the mask then it’s airtight and so should be watertight. Points to check are that it’s not pressing on the bridge of your nose or that it’s too tight to the sides of your eyes. When adjusting the mask strap (important if you are going diving) do not pull the straps to tight as you may burst the blood vessels in your eyes, giving you red eyes for about a month! Note: If you have a moustache the hairs will break the seal of the mask so you can either trim it, put Vaseline over it or put up with the ingress of water. Sometimes the more supple silicone seals on the dearer masks will seal over a moustache but we do not guarantee it.

Buoyancy Aids and Life Jackets:

It is important to get the correct floatation category for the sport you are doing. As a rule buoyancy aids are rated either 50 Newtons or 70 Newtons with 50N being the most popular. These are best used for dingy sailing, kayaking, kitesurfing, waterskiing etc. Life Jackets are rated 100N, 150N and 275N and are aimed at power boating and yachting.

Buoyancy Aids:

These are designed to assist in keeping you afloat but this means that you have to help yourself by treading water. A good fit is more important than weight ratio in a buoyancy aid as you do not want it to ride up over your ears when you hit the water. With children it is best to have a crotch strap and use it for the same reason.

If you are waterskiing, using a ski biscuit or jet skiing, etc, it is best to look for a buoyancy aid that has at least two buckles but preferably four buckles as a fastening. Zips on their own do not do the job when falling into the water at speed.

If you are sailing, kayaking, kitesurfing, etc look for a buoyancy aid that is cut short in the body so that you can either use a harness hook or that it does not ride up around your ears when you sit down.

Life Jackets:

100N jackets tend to be of a foam construction for buoyancy and for use on inshore & coastal waters. They give a reasonable assurance of safety from drowning in calm waters but not guaranteed to self right an unconscious user wearing waterproof clothing and should not be expected to protect the airway of an unconscious person in rough water.

150N jackets can use airfoam or air only for floatation and can be used in most conditions giving a reasonable assurance of safety from drowning to people not fully capable of helping themselves but may not immediately self right an unconscious user wearing heavy waterproof clothing.

275N jackets have buoyancy provided by air only and are aimed at users who are offshore wearing heavy waterproof clothing in severe conditions. They give a greater assurance of safety from drowning and while they cannot guarantee to self right an unconscious user the buoyancy they provide should ensure they will in the majority of cases.

Manual or automatic option:

A manual operated life jacket delivers full buoyancy in approx 5 seconds by way of pulling a lanyard that fires a CO2 canister to inflate the life jacket. The life jacket can also be inflated by mouth but do not breathe in the contents of the life jacket once it has been inflated with CO2. The automatic inflation operates when the paper retaining collar releases when in contact with water, with the CO2 canister being pierced and thus inflating the life jacket within 5 seconds. Can also be inflated orally. Note: the auto version user should bear in mind that this is not a suitable option for use in a small boat as a wave breaking over the person wearing the life jacket will in all likelihood set the life jacket off.

Harness option:

This is aimed at the sailor that may need to be clipped on to the boat and therefore reducing the chance of being lost overboard in rough weather or when working on deck. Harnesses are of a strong construction with a stainless steel ‘D’ ring for attaching a harness line too.

SPEARFISHING:

A great way to get a free meal ! but care should be used as they are deadly if you are not careful. A rule is that the longer the speargun the more accurate it will be but if you are new to the sport it is best to start with a shorter speargun. Our advise would be to start with a speargun of either 500mm or 750mm in lengh as they are easier to load and handle in the water. These spearguns are great for getting fish that are under rock ledges or where visibility is not that good and are easier to store on a boat for that impulse use. With any speargun over 750mm in lengh, most people will find difficult to load and manoeuvre in the water and these spearguns are best for use in open water with good, clear visibility. You should always try to get close to the fish; as an idea a range of 3 metres is about as far away from the fish as you should be. Remember that objects appear about a third bigger underwater and don't forget to secure the spear to your speargun with the lanyard. Good hunting!
