I am mostly spearing smaller rivers and lakes and didn't have the cash to buy a spear or speargun so i looked into making my own.
I used
fiberglass rod
small finishing nails
sheet metal
1/4" steel rod
eye hooks
latex surgical tubing
parachute cord
small cord/rope or shoe lace
45 lb. steel leaders
steel beads
power drill
vise
metal drill bits (various sizes)
hammer
vise grips
sander
metal file
hack saw
