Picking the Right Rob Allen Speargun For You
Rob Allen has always been a great manufacturer of Euro style spearguns. With nine different size options in the arsenal, there is a speargun option that will work well for any spearfishing. Rob Allen Spearguns have legendary durability, which has always set them apart from other “Rail Gun” style spearguns. These spearguns are manufactured in South Africa. They are designed for a tough environment, and even tougher fish. Rob Allen Spearguns are the standard for a streamline, and durable euro style speargun all over the world.
These spearguns are measures by the millimeter. That means the Rob Allen Tuna 700 has a tube that is 70 centimeters in length, and the Tuna 1500 has a 1.5 meter tube. The model number corresponds to the length for all the models. Rob Allen has a number of models of spearguns, but over the years we have found that the Tuna Models are our favorite.
Short Range Rob Allen Spearguns
The short range spearguns have maneuverability as a priority. They give up some range because they are shorter. Just because these spearguns are short doesn’t mean they lack power. All Rob Allen spearguns are powered by two 16mm bands. That means they store approximately 220 pounds of force to launch the spear shaft. Here is a breakdown of the shorter range spearguns in their arsenal.
Tuna 700
The Tuna 700 is the shortest speargun Rob Allen manufactures. It is one of the most maneuverable spearguns on the market. This speargun still has the power and range you need for large fish in limited visibility. The Tuna 700 is particularly useful while spearfishing under ledges or in holes. The maneuverability makes this a lethal hunting tool in tight spaces.
Tuna 800
The difference between any two adjacent speargun lengths is minimal. Ten centimeters is just under four inches. Typically a speargun’s range is determined by its length. Most spearguns have a range of two or three times the distance from the back of the band slot to where the band wishbone connects to the spear shaft. That means with each increase in a Rob Allen Speargun Model you may add about a foot of range. As spearguns get longer they become less maneuverable. So as you are picking the right Rob Allen Speargun for you you need to weigh your options for the diving you are doing. The Tuna 800 is solidly in the middle of the shorter range models.
Tuna 900
The Rob Allen Tuna 900 speargun is really the end of the short range spearguns in the Rob Allen line. With a maximum range of eight or nine feet (2.5 meters) it still counts a maneuverable, but can be a little much for tight spaces under ledges and rocks. In challenging visibility you can be stuck with not being able to see the end of your speargun. From a safety perspective it is important t be able to see beyond the tip of your speargun. You need to be able to identify your target, and what is beyond it. If you are frequently diving in about ten foot of visibility and shooting fish in the column, or in the open on the reef the Tuna 900 makes for the perfect combination of range and maneuverability.
Mid-Range Rob Allen Spearguns
The Mid-Range Rob Allen Spearguns are some of the best all around spearguns on the market. Because these spearguns are so streamline they track well in the water. The tracking helps get you on target quickly and accurately. These spearguns also have the range and power to land larger reef fish and even smaller pelagic species.
Tuna 1000
The Rob Allen Tuna 1000 can still be used as a short range speargun in a pinch. This is a great starter speargun length. It is a bit long for shore diving in limited visibility, and it is a bit short for landing amberjacks or cobia. With that being said, it can do both with some luck and skill. The Tuna 1000 will teach you to be a skilled hunter, while allowing you to learn what else you may want in your next speargun.
Tuna 1100
The Tuna 1100 is probably the best all around speargun in the Rob Allen line of spearguns. With a maximum effective range of approximately 11 feet (just over 3 meters) just about everything on the reef is a possibility. The Tuna 1100 still is streamline and maneuverable. This is also a popular length to convert to a roller speargun. Converting the Rob Allen Tuna 1100 starts to tuna this model into the start of a bluewater speargun. It increases the range another four to five feet. By using the Manny Sub Roller conversion kit you have the option to turn it into a single roller, or a double roller. It really is the best Spearfishing Railgun for spearfishing on the reef, or even bluewater spearfishing with a few modifications.
Tuna 1200
The Rob Allen Tuna 1200 is where these spearguns start to get a bit long. It is a great speargun for reefs with clear visibility where closing the distance on fish can be difficult. On reefs where you need the range these are great options. The challenge with these spearguns at this length and longer is that they become hard to load. The tigger mechanism on the Rob Allen spearguns are very far back on the speargun. This is great because it allows you to get the maximum range for the length of the speargun. The challenge with the trigger mechanism being so far back is that you need to use specific loading techniques to properly load the speargun easily. For a demonstration please look at this post and video. Adding the optional Rob Allen Loading Pad is also a method to make it easier to load the speargun.
Long Range Rob Allen Spearguns
The Long Range Rob Allen Spearguns are very specific tools for a narrow range of divers. These rail spearguns have the ability to do some bluewater spearfishing for some very specific species. Because of their low profile in the water they are ideal for deeper dives wile bluewater spearing. They do have their limitations. They lack enclosed tracks, and are limited by only having two bands. Having more bands would cause greater inaccuracy due to overpowering, but the two bands limits the penetrating power of the speargun. There are several pelagic species that these guns have enough power to get through. Other species, like billfish and larger yellowfin or bluefin tuna may need a larger speargun to have a good chance of hanging them.
Tuna 1300
The Tuna 1300 is a great introduction too bluewater spearfishing. It has the range to start targeting pelagic species in a serious way. It is not an easy speargun to load, but it is certainly the easiest of the long range Rob Allen spearguns. If you are specifically targeting bluewater species you may want to look at a longer speargun. If you do some diving on the reef and have to take long shot this speargun will still work for some spearfishing on the reef. You do need clear water to use the speargun effectively.
Tuna 1400
The Rob Allen Tuna 1400 is a big speargun. It is a long speargun to move through the water. It is still streamline, just like a of these spearguns, but it is still long. The handle being so far back does make moving such a long object through the water. There are some tricks to make it easier. IF you keep the speargun tucked up under your body as you dive it gives you the leverage necessary to close the distance on your fish, then use the motion of pointing the gun to get on target and further close the distance on your target.
Tuna 1500
If the 1400 is a big speargun this one is just a challenge. At some point is is just hard to transport spearguns while traveling because of their length. The Tuna 1500 takes a 190cm spear shaft. Trying to transport a 2 meter long bag around the world has its challenges. It gets expensive. This speargun has some ridiculous range. It can launch a spear shaft approximately 16 feet and punch through most fish. It doesn’t have the power to do Billfish, but Wahoo, Mahi, and even Dogtooth Tuna are all possibilities with this beast.
Choosing the Rob Allen Spearguns You Need
There is a lot of information about all the different lengths available above. When it comes down to it they all have their place. As a diver you just need to identify what your Neds are and find the right gun that meets most of your needs. There is no single perfect speargun that is great for shallow dirty water, but will also land wahoo from 20 feet away. Fortunately there are affordable spearguns, like Rob Allen, that are also sturdy and reliable.
