It's no secret that when the barometer moves, the fish bite. And when your home or cabin is outfitted with this accurate barometer, you will always know when you need to be packing up the boat and heading for the lake. The round brass frame gives it a nautically inspired look that's right at home on a boat or in a living room. Adjustable up to an altitude of 4,000 feet above sea level. Size: 5-1/4" (diameter) x 3" (depth).
