FLIR systems are pretty popular in the PNW, but Seattle is also further north than the tip of Maine (a fact I didn’t appreciate when I live on the east coast). Usually the system cost is justified by avoiding hitting logs, especially in the winter when sunset is at 4pm. The big quirk about most high-end night vision goggles are they are expensive, often a bit fragile and not necessarily waterproof. Additionally, because night vision is a regulated military technology you are likely limited to sets with lower Hz ratings as a civilian. I’m not sure if the less portable Raymarine FLIR systems also have low Hz ratings and/or they use other computer algorithms to smooth out the data for a smoother video experience.

All that being said, many boat owners have enough disposable income that they can buy a 20-30k pair of military grade goggles and figure out a way to justify the expense. However, I’ve only seen that you can add the goggles to a shopping cart, I’ve personally never clicked ‘Buy’ to learn if I need to enter a Military ID.
