Spearfishing has been popular all over the world for many centuries now. Early spearfishers used to spear fish from rivers and streams, often using sharpened sticks. Nowadays, however, spearfishing can be done in a variety of ways, using a variety of gears. Some of the ways in which spearfishing is carried out include free-diving, snorkeling, and scuba diving. And one of the most common spearfishing gears is the speargun.
Considered an essential and undeniably useful piece of diving equipment, the speargun is a device used for shooting underwater by way of gas under pressure, or by a strong rubber band or powerful spring. It is basically used to catch fish.
Like your basic diving equipment, this underwater gun is classified according to its users? level of expertise. It is also important to take into the account the type of environment for which the speargun is to be used. After all, this diving equipment is just as dangerous as the most common types of guns.
Only experienced divers and spearfishers should use the advanced or complicated type of spearfishing gun. The most common ones normally used by divers of all levels of expertise are the band style and pneumatic guns. A pneumatic speargun is powered by air and can be re-compressed underwater. It is usually used for close kills. A band style spearfishing gun, on the other hand, has one to three bands which are pulled back and put into notches on the spear.
Power and precision are important elements for a speargun. The most accurate and powerful ones are those with an inline propulsion system.
These spearfishing guns are normally in 16 or 20mm. For divers who are basically new to the sport, the best option would be to use the 16 mm one as it is best for a beginner's level of expertise.
Although some locations consider it illegal to spearfish using a speargun or any SCUBA and artificial breathing apparatus, there are still quite a number of scuba divers who spearfish for fun or as a sport.
If you have ever been scuba diving it is possible that you have experienced the nosebleed scuba diving drama. This happens to many scuba divers especially beginners because they are often unsure when to stabilize however there are many reasons that divers experience nosebleed scuba diving. In order to discover why you are getting nosebleeds while diving it is essential to pinpoint the problem early and then eliminate it to prevent further episodes as nosebleeds can be a frightening thing.
Nosebleed Scuba Diving During Descent
These are very common as the nosebleed scuba diving individual is experiencing these effects of a little thing called 'mask squeeze'. Mask squeeze results from not equalizing the pressure in the mast to match the water pressure and it creates a vacuum in the mask and this directly affects the nasal passages.
For one reason, very small and weak blood vessels can rupture within the nose cavity and cause that nosebleed due to this pressure within the mask. This can easily be remedied by performing a slow descent while frequently adjusting the equalization of the mask.
One of the most common sources of this event occuring is that the diver is congested and doesn't have clear sinuses. Many divers take decongestants such as Sudafed for an example that can help clear these passages to avoid unnecessary pressure within your nasal passages. Most of these incidences are due to the very simple problem of blocked sinuses as high pressure in a plugged sinus can cause excess pressure and henceforth causing a tear that results in a nosebleed.
Most nosebleeds stop immediately as you come out of the water and don't warrant an emergency room visit or medical advice. The diving instructor will verse you well on this because although it is common, it scares many potential scuba divers away after only the first time because they have experienced this type of nosebleed and they stay away from it forever not realizing how easy it is to remedy.
You might be surprised to know that it in fact infers pressure even in reading those words together and it is no surprise, if you are at all knowledgeable when it comes to this hobby, it is diving into deep water with apparatus designed to feed you air and offer you equalization so that you don't burst from the underwater pressure.
Nosebleed scuba diving can be a natural result from diving in too deep of water but also can be an indicator of your sinus health. Research all you can before jumping in feet first into diving adventures because it can pose serious ramifications.
