My father in laws perfect Christmas gift would be to have a remote controlled fish with a video camera to take underwater pictures of steelhead in the river to aid in fishing. We've discussed it for several summers while waiting to spot fish. Now were seeing plans that odfw is going to use drones to track fish from the air. Looks like the Navy is working on something like this, http://www.autoblog.com/2014/12/12/watch-us-navy-test-remote-controlled-recon-fish-drone/

Merry Christmas!
