Designer Jaewon Choi's "Beriscope" is an interesting blend of aquatic technology. It's a fishing rod that isn't for catching the critters, but instead for viewing them without ever having to enter the water yourself. Instead, you cast a camera out into the water and then use the Beriscope like a periscope, watching from the shore. It's just a concept, but it seems like it'd be a pretty good way to kill some time by a lake or river.
