Before you go look at new products, it helps to know what you’re looking for in a list first. Each brand of gun selection will have parts where you’ll have to know your dive’s info to know the right gear to purchase.
Here’s a load of speargun parts you’ll have to familiarize yourself before shopping for one.
If you're ready to look for the best speargun for you, check out our guide: The Best Spearguns for All Skill Levels
- Closed Muzzle: This design gives beginners easy loading access to an entry-level speargun without the shaft going all over the place as it has a piece of plastic going up and around it.
- Open Muzzle: This design is typical in most spearguns, but it doesn’t have the plastic piece that is present in the closed design
The roller head uses the barrel length to propel the spear with much power from a single band. It also helps mitigate the recoil while providing better accuracy and power.
The band selection depends on the sort of shaft and wishbones you’re using, but you can switch it out if you like.
- Standard Rubber Band: These are threaded into a Dyneema Bridle or wishbones
- Horizontal Band: These are threaded into the actual muzzles with metal-articulated wishbones
- Roller Band: Unlike the other ones, these are not closed-loop, but they’re a bit tricky as you’d have to consider the band thickness and inner diameter. With the open-loop design, you can unload the band when you’re not shooting to decrease the band’s tension, lengthening its lifespan.
Speargun Barrel Materials and Shapes
Pipe Gun: This standard and simple gun is made of Aluminum from end to end. The muzzle is in its front, and the handle is in the back.
Cuttlefish Barrel: This lightweight gun has a cuttlefish design that allows it to cut through the water and track your target fish easily. This design comes in handy with long guns as it offers a better fishing experience, allowing it to cut through the water from side to side.
Wood Barrel: Made from wood such as teak or mahogany. These barrels have been aged to prevent warping and protected with an oil or lacquer finish.
There are also hybrid styles that have a wood base with an integrated carbon tube. These ones are nice especially as travel spearguns where you can break it into two smaller components to carry on a plane.
- Short: Spearguns that are 75 centimeters(cm) down are for when you’re spearfishing in murky or dirty water and cave hunting.
- Middle: Spearguns with the length of 90 to 120 cm are great for shooting in reefs and an all around day at the water where you have good visibility under to shoot bigger fish.
- Long: Spearguns ranging from 120+ cm are awesome for your bluewater fish spearfishing, and anywhere you’re deep diving close to perfect visibility in the ocean.
- Aluminum: As the most common material for most speargun selection, Aluminum offers great durable quality equipment, although it is a bit heavy to carry.
- Carbon: Carbon barrels come at high prices. But if you’re typically looking for a lightweight gun, they are a solid choice. Additionally, this material allows the gun to absorb a lot of recoil and noise.
- Wood: Wood is heavy and hard to maneuver and trek through the water. But all divers and spearos will love its ability to absorb recoil. This helps especially when targeting bigger fish as it allows you to still accurately shoot them without having to worry about recoil.
Your speargun has a sharp tip for piercing your target and a flopper to prevent it from escaping after it’s gotten into the shaft.
Some blue water spearguns have slip tips that come out of the other side of the fish as the shaft engages to secure the catch. Your shaft has notches on the other end to allow multiple bands to be loaded on the same tab.
As shafts have different millimeters(mm) and diameters depending on your target fish, here’s a guide.
- Small Fish: 6 mm shaft
- Medium Fish: 7 mm shaft
- Big Fish: Bigger mm shaft
Shafts also come with either shark fins or notches for loading your bands. If you’re using a dyneema wishbone for your bands, opt for the shark fins style. It tends to not damage wishbones as much.
Tracks and Rails
The rail of your barrel will help guide your shaft out as you shoot, improving your accuracy. An enclosed track gives a follow-through accuracy of shooting as well.
For some lower-end, entry-model gun, you won’t see a track and rail, so it does not provide extra accuracy.
Handle and Trigger Mechs
- Plastic: This style is more common in low-end tier spearguns. It cannot bear much weight and will not last long.
- Stainless Steel: Stainless steels give more durability and can hold more tension and power when paired with bigger bands. This is currently the latest and most common trigger mech design as it can last you several years.
Outside of just materials, there are different mechs such as roller mechs, reverse mechs, and other configurations. Unless you’re building or modifying your speargun, going with a solid brand stainless steel mech should be sufficient for a beginner.
Your trigger mech will determine if you need Euro shafts or American shafts.
Some spearguns will have a reel mounted on it, some horizontal and others vertical. Reels come in handy when you’re diving deep, and you shoot your prized size fish. If the fish holds up, you can hold your reel out, swim up without letting your gun-free and track the fish down.
If you’re not up to using a reel, you can go for the simple float line you attach to a float. This allows you to let go of your gun after you shoot your target and let the fish take your float without worrying too much.
Your float has a lot of uses for your spearfishing and scuba dive. It can be as simple as just a marker, or you can use it to hold your gear. A float is necessary for any dive taking into account your safety and in order for you to get a top-of-the-line experience from it.
