AH! yes!....the pocket fisherman!...you’d have better luck catching fish with a dart!
One day, a friend was screwing around with one of those, and latched onto a bluefish that was about an 8 pounder, about 26 or 28" long. He managed to fight it for about 5 minutes, at least, before it snapped the line. Funny as hell. Wish I had a video of it.
Bluefish are vicious saltwater fish.
