Spear Points

Introduction

There are many different types of tips/points for a shaft, I will try to give as much information as I can about as many as I can here.

Spear shaft types

There are two main types of spear shaft tip types, this will dictate what kind of points you can use

• Fixed : the tip/point is fixed on the shaft, it is in integral part of the shaft and cannot be changed. If you damage the spear tip you have to replace the whole spear or find a way to fix it (e.g. resharpen a point). The advantage is that the spear is more streamlined and damages the fish less (smaller hole); they are really thinner than the threaded shafts. The disadvantage is that you cannot just swap out damaged points nor can you adapt the point to the type of fish. These are also called "Euro" spears/shafts because they are the default on Euro guns. Here is an example:
  
• Threaded : the shaft has no tip but is instead threaded. This allows you to change the tip, either when it is damaged or to adapt it to the fish/hunting style. The advantage is the flexibility, the disadvantage is that it is less streamlined than a fixed shaft (it makes a bigger hole), it damages the fish more and it can twist off. The advantage is the flexibility, you can choose between tridents of flopper tips, different types of points, single floppers, multiple floppers, etc. Good tips can be the price of a Euro spear so keep that in mind, the flexibility come with a price. Threaded shafts are popular on US spearguns. Here is an example:
  

Tips/Points

There are two main types of tips:

• Standard flopper/flopperless tips: the are the type you will encounter most of the time, they are essentially a point and will penetrate the fish well. They are made to puncture a hole in/through the fish and if there is one or more floppers these will anchor in the fish to keep it from escaping. They have the added advantage of being fast and to travel far and relatively straight.
• Tridents: You will see these on smaller spearguns usually that are used to hunt in holes/caves most of the time. The reason for this is that due to their shape they are less hydrodynamic and travel well only on short distances. They don't shoot as strait over longer distances also and if the gun is too powerful they would be completely damaged if they hit a rock. Since with a less powerful gun in close quarters you don' t have much force, the trident is great as it immobilizes the fish due to multiple trauma. They are also more forgiving to bad aim but make multiple holes in the fishes flesh.

Standard flopper/flopperless tips 

These are caracterized by:

• The number of floppers
• The point itself

Floppers

This is a type of barb that is mobile on an axis, a point/spear can have different number of floppers:

• No flopper: This is usually only for freeshaft setups (where the spear is not connected to anything via a line. The spear is just just to penetrate the fish and the hunter either has to be sure he immobilizes the fish by hand of by the shot itself. It doesn't make much sense to have a flopper for this type of spearfishing since the fish would swim away with your spear, having no floppers of barbs means it will usually fall out. The hunter can have several spears and chase the injured fish and shoot it multiple times. You usually take a fixed tip spear with a single flopper and then you either take the flipper off or cut it off at the flopper (the flopper hole can make it weaker) and make a point again.
• One flopper (Hawaiian): only one flopper, if it breaks you only had one so the fish gets away. Hawaiian means that it opens downwards, the idea being it will deploy with gravity's help. You can use a little rubber band to keep it closed while hunting if you want, although this may cause it not to deploy on soft fish, thus defeating the purpose. Influences the trajectory in one direction some say. One flopper tips are the default on Euroguns, they look like this:
  
• One flopper (Tahitian): only one flopper, if it breaks you only had one so the fish gets away. Tahitian means that it opens upwards, the idea being it will not deploy with gravity's help meaning you can poke it in holes and such without it getting caught. Influences the trajectory in one direction some say. One flopper tips are the default on Euroguns, they look like this:
  
• Two floppers: this type has two floppers, either symmetrically or not, these are common in the USA. Having two floppers means you have a "backup" flopper if one breaks, if one doesn't engage or if one flopper closes while the fish struggles. It also doesn't modify the trajectory since it is balanced. A symmetric double flopper point has two floppers attached to the same flopper hole, so you get one on each side like this:
  
  A non-symmetric double flopper point has two holes, one flopper in each hole and they are on opposite sides horizontally. These are specialty tips that help in cases where you hunt soft and hard fish, in soft fish both will (normally) engage/penetrate and in harder fish both may or only one may depending on the toughness and distance. They share the other traits the "normal" double flopper point has. This is what they look like (the one on the right is a custom made point by Linghunt Engineering Inc.):
  
  
  
• Three floppers: these are ame as two floppers but with three floppers. I have never tried one of these, they should behave like their 2 flipper cousins but with two backups and to hold better to fish. They are quite rare, I have never seen one myself in real life, they look like this:
  

Point Types

Here are some popular point types:

• Bulletpoint (aka Rockpoint): These are the standard type, they are like a pencil point. They are all-around/general points and are also good when hunting around rocks/reefs as they are less fragile than the other two types. They don't penetrate as well in tough fish though. Here is an example:
  
• Tri-cut: they have three flat sides cut into the point, the edges are often sharpened. They have great penetration in tough bone or skin but are more fragile and will be damaged if they hit rocks. These are used in bluewater hunting on big fish, here is an example:
  
• Arrowhead: these are the rarest of the three, they have a shape like an arrowhead (hence the name) and have sharpened edges. They share the same pros and cons of the Tri-cut points, they have their use for tough small to medium sized fish, here is an example:
  
  Some points, usually threaded, allow you to literally change the tip of the point also. This means that you can not only change the point type depending on the conditions, the fish, etc, but also the tip of that point in case it gets damaged/worn out from hitting rocks. This is a nice idea but I have never tried those out. Here are some examples (the one on the right is a custom made point by Linghunt Engineering Inc., the same as the non-symmetric double flopper point shown above):
  
  
  

Tridents

• Standard Tridents: Can have 3 or sometimes 4 points which are thinner which are not aligned. The points have non-moving barbs. These are good on smaller (and maybe medium) fish and smaller guns. The usage where they really shine is to catch a fish in a hole, be aware though that anything else in its path will stop the trident, something that is less of an issue with flipper spear points. They slow down the spear very quickly, so at a distance of more than a meter they are not really useful. They look like this (the one on the left is for Lionfish):
  

• Flat Tridents: Can have 3, 4, 5 or 6 points which are thinner and aligned. The points have non-moving barbs or small floppers. These are good on smaller (and maybe medium) fish and smaller guns. Due to their flatness they are not as convenient in holes as the non-flat type. They share all other traits with the above type but they do have one advantage however which is that they are much more forgiving to bad aim :-). The plastic and stainless steel ones are not as robust as the all stainless steel ones, they tend to break f they hit rocks at high speed. Flat tridents look like this:
  
  
  
  
• Paralyzing tips: Used often on pole spears, this is like taking a bunch of straight thin (often thinner than for tridents) metal bars and bunching them together at the bottom and sharpening the tips (with or without barbs). The idea is that they will paralyze the fish with multiple insertion points and the side forces tighten the hold as the tip goes into the fish. Useful for smaller (and maybe medium) fish. These also slow down the spear quickly and are fragile. Different models have a different number of tines, three seams to be the optimal amount. They look like this:
  
  
  
  

Threaded specific

Threaded points come in three types:

• Standard/Non-Rotating: these are the standard threaded tips. They are not expensive and you find them everywhere, literally, if you buy a threaded point t will probably be one of these. The big downside is that they can unscrew, for example if the flopper is inside the fish and the fish rotates (this has happened to me!). They can even unscrew without a fish's help (also happened to me). You can use thread tape/nylon to help it stay put a bit but you have no guarantee it will. Tridents are exclusively of this type. Here is an example:
  
• Rotating: these are only made (to my knowledge) by JBL International and A.B. Biller. They are much more expensive than regular points but they don't have the issue with unscrewing themselves but their footprint is a little bigger (since you have the rotating mechanism) compared to some non-rotating points and they may be more fragile although I have never had this issue. One downside to them not unscrewing when the arrow rotates is that if it gets stuck somewhere you can't just unscrew it (thus loose the point) to save your shaft (also happened to me). Here is an example of what they look like:
  
• Break-away/Slip-tip: this is an old mechanism, they come either with or without floppers, without being the oldest type. The tip itself is disconnected from the part that screws onto the shaft, they are connected with a wire or string. When the point goes into a fish, it disconnects and stays inside (or on the other side if it went through). This helps a lot especially when the flesh is soft, a regular shaft and point can tear the flesh and the fish can get away, with a breakaway this is less likely to happen. The downside, other than the cost, is the fragility and stability. Fragility because if it hits a rock it can break beyond usability, stability because it can fall apart if there is some slack and it is harder to put together. Pole spear slip-tips are made to be more robust than speargun slip-tips; they can handle rocks better since they have more engagement of the stem on the head and have thicker wall thickness on the head. Here is an example of the two types I have spoken:
  

The thread size varies depending on the spear diameter, most are M6 (6mm) or M7 (7mm) but check before! There is also the pitch to take into account, this is the spacing in between two threads. A better way to difin the correct thread would be to use the pitch in conjunction with the diameter: 6mm-1, 7mm-1 , 8mm-1.25, 5/16"-24. You can buy adapters in case you have a large cache of points for one size though. An adapter does add a new point of failure and will make the footprint bigger, here are two adapter examples:

• M6 female to M7 male:
  
• M7 female to M6 male: 
  

This wraps up this post on speargun points/tips, I hope it will help someone out. If you have any remarks or questions please don't hesitate to write a comment. I would like to thank John martin for his comments and contribution.
