Hello, i have never been spearfishing and was looking at guns when i came across the pole spears. For one they are MUCH cheaper (im 15 with no cash), but i was wondering if one could teach themself how to work with it. To me it looks harder then a gun, but im no expert. I was wondering exactly how it works and if anyone could tell me what's a good quality weapon. Oh yea, i'll be in all freshwater with it.
