Listed below is a breakdown of the most common speargun parts, knowing how these parts work and how to replace them is essential when using and attempting to maintain your speargun. Starting from the front of the speargun and working backwards:
Speargun Parts Guide
The tip or head is the sharp part at the end of the shaft. Like an arrow, the tip is sharp and cuts through the flesh of the fish upon impact. Read the speargun tips section for more speargun parts info.
The shaft is the spear itself, the shaft is the metal rod that shoots out of the speargun. Shafts come in different lengths and thicknesses. The types of metal used in shafts also vary, with different types of steel providing various degrees of strength, spring and flexibility in the rod. The shaft is one of those speargun parts that you need a good supply of, as shafts tend to bend out of shape from time to time.
The muzzle is the located at the very front of the gun. The speargun muzzle has a round hole or holes that holds the rubbers. The muzzle needs to be strong to take the strain of the stretched rubbers.
The shooting line is what connects to the spear and the underside of the muzzle. Some would say the shooting line does not fit the category “speargun parts”, however it is a permanent attachment to the speargun therefore it is a part of the speargun. The shooting line needs to be of good quality cord, preferably dyneema, fishing line is not recommended. Be sure to check the integrity of your shooting line often and replace it if there are signs of wear. Left unmaintained the shooting line can break meaning you could lose your fish and your shaft!
Barrel and Stock
All speargun parts are important but the barrel or stock should be of the highest quality, avoid cheap spearguns that don't manufacture a quality barrel and stock. The barrel of the speargun is the body of the gun, the barrel in some spearguns sits inside the stock, although most of the time the barrel and stock are one piece. The speargun barrel can be made from many different materials including wood, aluminum, graphite, plastic etc. The speargun barrel has either a built in or detachable rail. The rail is a groove that the shaft slides down when fired. The speargun barrel needs to be strong so it doesn't flex during the loading of the rubber. The speargun barrel and stock need to be resistant to the constant exposure of saltwater and sunlight.
With the exception of Pneumatic spearguns, all spearguns need a rubber to propel the shaft. The speargun rubber attaches to the muzzle and then to the bridle. The rubber needs to be of good quality to withstand the constant strain of being loaded into the speargun. It is important to check your speargun rubber frequently for any flaws. Cracks in the rubber will start to develop over time and if left unchecked can cause a breakage. The last thing you need is you speargun rubber to break when spearfishing. When shopping for speargun parts it is recommended to buy top quality speargun rubbers and be sure to take a spare rubber with you when going spearfishing just in case.
Bridle / Wishbone
The bridle (aka Wishbone) is the part of the speargun that connects first to the rubber and then to the shaft. The bridle sits inside the notch of the shaft. Bridles can be either metal or braided cord. Metal wishbones can be one of the most dangerous speargun parts. They have caused many accidents with people hurting their fingers when the metal wishbone comes out of the shafts notch. This actually happens quite often. It is recommended to instead use a braid wishbone for your speargun, these cords are made from strong dyneema and can withstand a lot of punishment, see the speargun parts store for dyneema bridles / wishbones.
The trigger mechanism is the most complicated part of your speargun, it has many moving parts. Read the speargun trigger section for more speargun parts info.
The loading pad or butt of the speargun is located at the very back of the gun. As the name suggests the loading pad is used to load the speargun, of all speargun parts this one is particularly important. For both safety and comfort reasons the loading pad needs to suit the shooter as perfectly as possible. When purchasing a new speargun it is recommended to test loading your gun before taking it spearfishing, this can be done out of the water but be sure to wet the rubber first. Some spearguns don't have a loading pad, this is not recommended for beginners, however on small guns it is fine as they don't require much effort to reload reducing the risk of an accident. Euro style spearguns normally do not have a loading pad. Some spearguns will allow for detachable loading pads which can be purchased through speargun parts providers.
There are other minor speargun parts, most of which are found in the handle and help make up the trigger mechanism. For the most part however these 10 parts listed above make up a complete speargun.
