Description
– When fitted properly, Doc’s proplugs help divers equalize
– Reduces “ear squeeze” caused by inability to equalize between the outer and middle ear
– Helps prevent outer ear and inner ear infection, vertigo and thermal reaction
– Without ear protection, 65% of scuba divers suffer from ear problems which keep them away from the sport (source: DAN)
Doc’s Proplugs can prevent swimmers ear, and ear pain by blocking water from entering the ears, keeping ears warm and preventing the flushing of water in and out of the ear. Ear pain and infection are caused by cold exposure and erosion of delicate skin and wax in the ear canal.
Upon descent, Proplugs prevent water from entering the ear down to 20 feet in depth. Once the diver enters greater depths, water will be allowed into the ear for equalization. Unlike other earplugs, ours includes a Scott’s valve which allows ears to equalize easily and let sound in. Our proplugs have been used by hundreds of divers for over thirty years who testify that proplugs are the earplugs for divers.
Equalization with Doc’s Proplugs: Doc’s Proplugs have also been used by divers who have trouble equalizing. Unlike other earplugs which are solid and would not be recommended for diving, Proplugs are vented to allow equalization. While the small vent allows equalization to occur it does not allow debris to enter and it prevents earwax from washing out which exposes delicate ear tissue. The Proplugs keep ears warm by storing the head’s conductive heat; the warmth provided by the plugs drastically reduces the risk of thermal shock. Due to surface tension the vented plug also reduces abrupt pressure changes from reaching the sensitive eardrum which contributes to easier equalization. Clear ears often to allow air to escape through the Proplugs vent and allow for better equalization. Proplug wearers who have trouble clearing their ears should check to make sure a lump of ear wax is not blocking the canal or butting up against the vent. If the vent is fouled by debris while descending it is best to remove the Proplug. If fouled while ascending, there is no problem because the air and water under pressure can escape around the Proplug.Hundreds of thousands of divers have attested to the benefits of Proplugs for relieving pressure in their ear during descent.
THERE ARE MANY ASPECTS TO SURFBOARD SELECTION THESE ARE THE POINTS TO CONSIDER
LENGTH
Typically surfboards are measured in inches. The length is measured from the nose to the tail. Choosing the length of the surfboard is dependant on your size (weight, height), board type and waves conditions you wish to use the board for.
WIDTH
The widest point of the surfboard is measured from rail to rail. Generally the wider the surfboard the more stable the board, while a board with smaller width maintains better speed and performance.
BOARD THICKNESS
Surfboard thickness is measured from the top deck to the bottom. The thickness again has a bearing on the board’s performance. Professional surfers will tend to go for the thinner boards as they are lighter and offer better performance.The thicker boards are stronger and because there is more foam under the surfer the boards are more stable.
ROCKER
The bottom curve of a surfboard. Generally the more rocker the surfboard has the more loose (manoeuvrable) the surfboard will be. Where the flatter rocker surfboards will be faster, although they will lack the looseness. The nose is the tip of the surfboard, the nose can vary in shapes and size. Basically the thinner the nose the more response the board will perform, while wider noses are better for stabilization.
STRINGER
Used to increase the strength of a surfboard, a stringer (normally made from wood) runs down the length of a surfboards (typically in the centre of the board from the tip of the nose to the tail).
Boards built with Epoxy, Carbon Fibre and soft boards generally don’t have stringers.
FINS
Generally heavier surfers require larger fins to hold the waves better. Although if you prefer to ride a looser (less hold in the waves), smaller fins would be a better option.
FIN CONSIDERATIONS
Fin configurations have an effect on the ways your surfboards perform.
The following are some of the more common fin configurations.
SINGLE FIN
The single fin was the original fin configuration for surfboards. Based on the idea of the sailboat keel. Single fins are added stabilization and control on the powerful, larger waves, although lack manoeuvrability
TWIN FIN
Are great for small waves, being fast and manoeuvrable, but when put into tight spots on larger waves, they become hard to control. Popular with Fish surfboards.
THRUSTER 3 FIN
Widely recognized as the standard fin configuration, the thruster answers the shortcomings of the single fin and the twin fins configurations.
The thrusters give you stabilization, control and manoeuvrability in all types of surfing conditions.
This concept was the brainchild of Australia’s Simon Anderson
QUADS 4 FINS
With four fins in the water, Quads boasts an extraordinary amount of holding power in larger surf.
You may think that having four fins would sacrifice speed by creating more drag, but this is not the case.
The both sets of fins are working together on the rail, which makers believe they creates less drag than a board with a centre fin.
The manoeuvrability isn’t sacrificed either, with fins directly under your back foot, the quads are very responsive.
KEEL
Similar setup to the Twin Fin, although smaller (low profile) fins are generally placed wider (closer to the rails) on the surfboard.
Popular with Fish and Egg / Retro surfboards.
