Rob Allen Scorpia Railgun Product Description


The Rob Allen Scorpia Rail Gun is a great choice for a diver who wants an amazing brand that is great quality yet at an affordable price point. The Rob Allen Scorpia's barrel is made from aircraft grade aluminum with a super thin yet strong wall. It performs at its best on small to medium sized fish however will still perform when confronted with larger fish. This particular gun is designed for shallow reef diving where it can be maneuvered quickly and quietly which is why the length only goes up to 110cm. When you are in shallow reef areas, you really don't want a long gun as it will have too much range so the Scorpia is perfect choice for around rock walls and reefs. It is available in lengths 90cm,100cm and 110cm.


The "Rail" in rail gun, means that there is a carved out rail down the length of the barrel where the spear sits which allows the spear to be guided out when shot making it more accurate. Dont be fooled though, your gun is only as accurate as you are! Equipped with a sinlge 16mm rubber in the single muzzle gives the perfect amount of power needed, however if you want to add more power you can purchase a 18mm or 20mm rubber that can be in place of the standard 16mm. The dyneema bridle in the rubber is what hooks in to the notch of the spear to pull the spear forward when fired and the rubber gives it the power to do so. 


The spring steel shaft is a 7mm in thickness and is extremely durable and comes with two notch's for the bridle to fit in. Attaching the shaft to the gun is a monofilament line that is rated to 180kg's and this is then attached to the muzzle underneath the barrel. Holding the mono tight to the gun when the shaft is in the gun is a line release. This holds the line out of the way so it does not tangle and will release when the gun is fired. There is a safety catch on the handle of the gun that sits just above the trigger mechanism, this is to be used carefully and not to be relyed on. Only load your gun when you are ready to shoot, do not load, flick the safety on and then get ready, if the safety catch fails, it could be potentially very dangerous. 


The general rule when purchasing a speargun and what length to get is determined on where you will use it. 90cm - 110cm are normally used in shallow reef diving as they are shorter and easier to maneuver in shallow water. 120cm - 140cm are normally used in open water aiming for the larger fish, this is due to them have a longer range which you need with bigger fish. This is a general rule though!

Care Instructions


  • Rinse with fresh water after every use to remove all sand and sea water
  • Keep rubbers in the freezer if not being used for long periods of time - this slows down the perishing process
  • Remove spear when cleaning and dry throughly before storing
  • Keep in a dry and safe place
  • Do not load out of water
  • Store in a gun bag if possible
  • Do not rely on the safety catch


Extras:   When purchasing a speargun, there are a few extras that we recommend you purchase to complete your kit. A float rope and divers float are the two main extras. The rope is connected to the gun at the handle and the other end of the rope is to be connected to the float, this will ensure you will not loose your gun by accidentally dropping it, or having a fish steal it! (It does happen). A pair of gloves is another item that we recommend you purchase also. Once you have shot your fish, trying to grab it and finish the kill can be very difficult without gloves. Fish are not only slippery but also have made spikes and teeth. Gloves will prevent cuts and scratches as well as grip. Here at Dive Warehouse we are loaded with information regarding spearfishing gear and tips so feel free to contact us if you have any questions.

What is the warranty?


Rob Allen Spearguns have a limited lifetime warranty on the handle, trigger mech and barrel.


Do I need a license to buy a speargun?


You do not need a license to purchase a speargun, howevere you may need a fishing license depending on which state you are in. In Queensland you do not need a fishing license.


How do I load my speargun?


The best place to load your spear gun is on your hip. Place the butt of the gun on your hip, lean over the gun to grab the rubber with palms facing upwards and pull with one swift movement towards you to hook the bridle on to the spear notch. If you can not reach the rubber (usually on 1.2m +) you will need to load the gun from your chest. Simply grab one side of the rubber with 1 hand whilst placing your other hand on the butt of the gun. As you start to pull the rubber towards you, push with the hand on the gun until you can slide the butt of the gun in to your chest and then grab the rubber with both hands and finish the load.


Where can I go spearfishing on the Gold Coast?


On the Gold Coast, you will need to stay out of all of the rivers and the broadwater. Stick to the headlands and ocean. There are fines if you get caught where you should not be and your gear can be confiscated. 


What length is best for me?


The best length of speargun for you depends on where you are spearfishing. If you are in shallow reef waters then a shorter gun from 50cm -110cm is perfect. If you are in deep open waters then 110cm - 140cm is perfect.


Which one is a beginner gun?


All of the spearguns work in a simular way. There is no such one as a beginner gun, its more about quailty and what you are prepared to spend for your first gun. The more you spend, the better the quality they will be.


Can I shoot the gun out of water?


No, this is dangerous and all spearguns are to be used in water only. 


What else do I need once I have my speargun?


Once you have purchased your speargun, you will need a knife to kill your catch, a float and flag to connect the gun to and your mask, snorkel and fins. These are the necessary items however there are many more things you can add on like a wetsuit, gloves, socks, stringer, flasher & more.
