'The Wave' is a revolutionary concept in tide clocks! The center disc turns to simulate the ocean's tides at a rate equivalent to one lunar second per pulse.
The tide clock's cycle is geared to Atlantic Coast tides (approximately two High and two Low tides per day). The highly polished and lacquered 6" brass case can be mounted directly on the wall, on a wooden panel, or on a mantle stand. A must have for all fishermen, boaters, and nature lovers!
Operates on a single AA battery.
