I want to buy the 75 cm Imersion Challenger gun. Could anybody tell me what lenght of sling i should buy (the 16 mm imersion black latex...but what lenght?)...and what kind of spare spear?

Mate where are you hunting and what type of fishes. If your after small fishes which I guess cos of the size of the guns then Im sure a 6.5mm shaft will be sweet. It shouldnt bend to easily unless you shoot a large reef fish that holes it up.

A single 16mm band would be adequate to lob a shaft that thin, but personally a single 18mm is even better. I have tried a single 18mm rubber with a 7mm shaft on my Ra's and it works quite well. As for the length a 30cm 18mm rubber would probably be good, I have a 50cm 20mm rubber on my Ra 110 which I use as a rough guide to rubber sizes on other guns.


A 22cm 20mm rubber that is hella short, when you stick that in the muzzle and put the bridles on that will be only 11cm long on each side of the barrel if you know what I mean. Do you mean 22cm total length of the 20mm.


Oh right screw in never used those, was thinking of Rob allens we just loop the rubber straight through the muzzle and tie bridle so I give my sizes as total rubber length.
