Probably for marketing purposes. I remember when I was younger I always liked the idea of fishing with a survival kit. I never really got to experiment it and now that i'm a bit older, I understand that in a survival situation i'd rather use my time to collect firewood and make a comfy bed with branches and twigs than trying to catch fish.

It all depends. Depends on the situation, on the people. Some people seem to love the idea that they might have something to catch food in a survival situation; I assume the "entertaining" factor is what makes them happy.

I don't believe in fishing kits at all, sure they would provide some entertainment but if you ever get lost or injured for real, you won't care about fishing at all. You'll be on the lookout for people or aircraft. Which is why I believe that, in a real survival situation, a whistle and signal mirror are paramount.

I would rather use the space used by a crappy fishing kit for more Tinder-qwik pieces.
