In the last video, we looked at under water spear guns and tested if they work as makeshift home defense weapons.
Turns out we were wrong in some of our findings – we stand corrected!
In any case, one of the biggest disadvantage of spear guns is that they have one shot only. This seems inadequate for the purpose – at least two shots are called for !
So we designed AND built one of the few all-metal weapons we ever made… a short (50cm) double shot spear gun that is no doubts effective both under AND above water.
See for yourself!
