With the power of First Mate II and First Mate II MS (Marine Scope), you can see at night like never before. Use them on any vessel or even around the house – these handheld thermal night vision cameras run off batteries and display their video on a built-in screen. First Mate II and First Mate II MS provide go-anywhere thermal imaging for clear vision in total darkness, and through smoke and light fog. Since it’s not permanently mounted to your vessel, you can take it anywhere. So stay out a little longer, even when everyone else is scurrying for the dock, and enjoy your time on the water with your new First Mate II or First Mate II MS.
