It's definitely a cool toy to have, and if you make a lot of night runs in heavy traffic, maybe a necessity. And yeah, it'll cause major shrinkage in your checking account balance. But it's a cool toy.
We have a FLIR camera that come with the boat. It is a pretty neat toy to have at night. It is really amazing and once you get used to it, it can be really useful. The only problem I have had is that I can get too fixed on the screen and I have to remind myself that I need to look out the windows!
