Choosing a Speargun

 

Hi everyone,

 

So you want to start spearfishing and the gun is the next item on your list yet you have no idea which one is good or which one to get! Well, don’t you worry yourself as we are here to help and this blog is going to give you some great information of the different brands and styles with features so you get a good understanding of what you are looking for.

 

Length:

The length of a speargun is the first question we get asked about and it is generally “which length is best for me”. This question is a good one and going to be answered right here, right now! The best length of a speargun depends on where you are diving with regards to the depth. You may be wanting to hang around the rock walls and jetty’s in the rivers where the depth may be 5-10 meters or you might have access to a boat and be doing most of your diving out on the reefs in open ocean at 10-30 meters. Depending on where you spend most of your time will determine the length as if you are generally in shallow waters, you don’t want a long gun where the full range is going to hit the ocean floor or rocks. A speargun’s shooting range is approximately 4 times the length of the gun. For example a 1m gun will have a range on 4m which included the gun barrel, shooting line and the spear. A long gun will be harder to maneuver in shallow waters so perhaps a 90cm – 110cm would be suitable as the smaller fish tend to come in closer so you don’t need the range. In open ocean, you are hunting larger fish and they don’t come in as close so you would need a longer range for these and a 110cm – 140cm would be perfect. If you are diving in a bit of both then a 110cm would be best suited however every good spearfisherman would have 2 guns. A shorts reef gun and an open water gun.

 

Style:

There are 3 different styles of spearguns including a rail gun, roller gun and a pneumatic gun. 3 very different styles, however the most commonly used is the rail gun. This particular gun is loaded with rubbers which gives it the power when fired. The spear sits on the top of the barrel in a rail that guides it out smoothly and accurately. It is the most popular gun as there are many different price points within the range and is perfect for beginners to professionals.

The roller gun is the newest on the market and although is very similar with the rail, the rubbers are much longer giving more power and shooting range on shorter gun length. This style is more so used for the advanced divers who want to spend a little more on their gun and are hunting large pelagic fish in open waters.

The pneumatic gun is air powered and does not get its power by rubbers. There is an air canister within the barrel which is pumped up, when the spear is loaded it pushes a piston against the pressurized air so when it is fired, the high pressure air is what propels the spear. This particular gun would be the least popular as the gun needs to be serviced each year which occurs a charge. Many boat owners use these guns to jump over board, shoot their dinner and head back.

 

Features:

All of the rail guns work in the same way….  you pull the rubber back, hook it on the spear, aim and then pull the trigger. However, there are features that change with each style and knowing what’s what is important. Let’s start with the spear. They come in a variety of thickness from 6mm to 7.5mm going up in .5mm increments. The thicker the spear, the better quality and stronger they will be so if you are shooting thick pelagic fish, we would recommend at least a 7mm or 7.5mm. Next is the muzzle, this is available in 3 different styles including open, semi open and closed. The muzzles also come in double or single with regards to how many rubbers they can hold. A single 16mm is a great strength to start as this will penetrate small to mid sized fish. When hunter larger fish, twin 16mm rubbers will give you more power, or you can choose a single 18mm or 20mm. Next is the gun bungee which comes on selected gun yet can be purchased separately and fitted to a gun that does not have one. The Bungee is a shock absorber and will take some of the strain off of the spear line when shot. Another feature would be metal components over plastic which will of course last longer. Some of these include the line release and the trigger mech.

 

Quality:

The quality of each gun will vary and depending on how much you are paying for it will determine the quality. For example if you purchase a gun for $99 (which are one of our popular price points) you will receive a great gun at a $99 price point quality. There will be less metal components with more plastic which will be a cheaper quality. If you look after this gun, it will last but will need some good TLC. Don’t look after it and it will not last. Purchase a gun around $500, you will receive a much better quality piece of equipment that will have more durable plastics and metal parts that will last many years. You get what you pay for which is a general rule for most things in life.
