What size speargun do you need?

speargun150With so many guns in so many set-ups it can be difficult to know where to begin!  With that in mind we have created this guide so you know exactly what you need, when you need it. Spearguns generally have a name plus a number.  The name relates to the type of set up it has like a ‘Rob Allen Tuna’ relates to fact that it is made out of aluminium and is powered by twin bands.  A Rob Allen Tuna ’90’ tells us the set-up (as above) plus that the barrel is 90cm long.  Notice that I said the ‘barrel’ is 90cm long.  In speargun measurements the length always indicates the barrel length but the overall length of the gun is much longer.  For the total length of the gun from handle to spear tip, you should always add on an extra 50cm.

The gun length ranges all have a specific job and specific purpose.  While its true that some people simply have a preference for certain lengths its safe to say that the guide below is accurate for the vast majority of the spearo’s out there.

 

Gun length Usage 
50 – 60cm These shorter lengths are commonly used for hunting caves & holes
70cm Commonly used in poor visibility, or by shorter individuals
80 – 90cm The 90 is by far our bestselling speargun size followed by the 80 and are perfect for the UK 
100 – 120cm These 100 – 120’s are traditionally used for targeting specific species like bream who never come too close, or for when the visibility opens up.  Also starting to get into the sizes used abroad on reefs with good visibility.
130cm The 130 is a great all-rounder for when spearfishing abroad.  It’s can be used for bot reef hunting and blue water spearfishing.
140 – 160cm Used for targeting the biggest fish in the ocean.  Strictly for blue water big game spearfishing

 

Most people have a 90 or an 80 as there primary speargun.  For the UK these are ideal lengths being short enough to track sideways in poor vis, while retaining enough power and range to deal with the biggest of bass/conger whatever.  The twin rubber Tuna version certainly assists with this offering huge power and range while staying deadly accurate with the rail (Its our best seller by far).

This is normally companied with a shorter hole hunter.  During the course of a spearfishing trip it is very common / desirable to explore caves and holes as this is where you can often find those big specimens resting away.  For this you need something short, stumpy and manoeuvrable otherwise you don’t stand a chance.

The hardcore will then often add a longer sniper gun to their fleet for the odd days that the visibility opens up and also for targeting wary fish that stay on the outskirts of the range of a 90.
