I was considering getting some flares as well. Great tips. How do the stick flares compare to the gun flares? The light stick is a great idea. I may have to pick some up to keep in my ditch bag or PFD.
I did get a nice C-Strobe for my PFD, that thing is amazingly bright! I had a white "safety" light for the PFD before, and it was junk. It barely made a good flashlight
I may get a small signal mirror for day time signaling as well. It isn't just night time when we may need a rescue.
I also just picked up a bike flag to put on my kayak light pole. I noticed with the swell, it is easy to loose sight of the kayaks. The flag seems to stand out pretty well. I just hope I don't get my rods tangled on it!
