Extra Speed for your spear

I was reading some old diving books and came across this and thought this was very interesting to know.
If you are using a steel spear shaft and it has starting to rust then it may be slowing down your shot. To prevent this here aresome ideas.

Try polishing the shaft shiny and smooth.
Next, try spraying a thin film of silicone spray on the track/rail of the spear gun.
Load the spear shaft as normal. Spray the silicone on the shaft covering the track/rail.
Simple, but this application will drastically decrease the amount of drag the shaft will experience against the track/tail when fired. The silicone spray is considered food grade quality and will not spoil the fish's meat or create any kind of biohazard. The silicone will also dissolve slowly off the track and shaft throughout the day of spear fishing. Therefore, reapply before each dive.

Maybe some Q20?

Q20 works but the problem with that is it gets on and in the fish and smells so its not cool cos the fish tastes funny where you speared it lol and not keen on eating oil lol

Ja , good point.

Vaaseline might also do the trick.

it might hey i didnt ever think of that !!!

If you are that worried about the resistance on the spear, you should go for a stainless steel spear and it will save you all the hassle

Stainless stell eventually rusts as well. especially if its been scraped against rocks etc

well at least mine did, unless I was not informed correctly about my purchase
