I got one halfway through last year. I used it quite a bit. Awesome.
Changes fishing completely for me. You can see bites that you would never know occurred.
You can compete with your partner for the fishes' attention. Saw a few big pike come in and stare, never biting.
I think the flasher is more important, more versatile, but the camera really makes things more fun.
Also, you can buy the aqua view underwater flood light and duct tape it to the camera for after dark. Big improvement over the built in lighting.
