How to use and care
Match the shaft length to your gun: the spear should suit the barrel length and give an appropriate overhang for the band setup. Always check that the notch and diameter suit your mechanism before use. Rinse the shaft in fresh water after every dive, dry it, and inspect it for bends, pitting or damage to the tip. A bent shaft should be replaced rather than straightened.
