What size gun should I buy?
Different sized guns have different uses;
60cm; For hole fishing, flatfish or very low visibility. Very manouverable, but with limited range. Some divers like to fit these with 5 pronger heads
75cm; The great allrounder, may be used for hole fishing or openwater. Short enough to be manouverable, with a lot more range than a 60. An ideal first speargun size. If you are only going to buy one gun for UK spearfishing, this is it.
90cm; More range than a 75, but a bit long for hole fishing. A good all round open water gun, particularly in the Southwest. My personal favourite
100cm; Useful for spooky fish in clear water. Normally only used in 30ft plus visibility. The extra 10cm of length over a 90 makes a big difference to range and manouverability
120cm;The South African standard. Very rarely used in the UK, as seeing the end of it can be a problem! Perfect for tropical reef hunting, with enough range for open water gamefish
140cm; Blue water special. For open water tropical gamefish The sizes of rubber powered spearguns refer to barrel length only.
The standard spear lengths for these guns are;
60cm gun; 100cm spear
75cm gun; 115cm spear
90cm gun; 130cm spear
100cm gun; 140cm spear
120cm gun; 160cm spear
140cm gun; 180cm spear
end up with several different sized guns for different uses. For UK diving
a 75 is the best first buy, as it has the widest application. A diver in Sussex
or Hampshire may also want a 60. In the Southwest where the water is generally
clearer, a 90 would probably be the next purchase. .
