If you love to sail, surf or simply stroll along the shoreline, a quartz tide instrument can be your best friend. It’s easy to use (no need to refer to tide tables), reliable, and low maintenance.
A Chelsea tide indicates the times of the next high and low tides by keeping track of the moon’s motion around the earth. Tide instruments keep an approximation of the average time between high lunar tides: 12 hours 25 minutes per revolution.
Our Polaris Tide instrument features a subtle contrasting matte and frosted silver dial with cobalt blue numerals, and forged solid brass case and screw bezel with handsome beveled glass. Designed to display tide readings for East Coast (USA) only.
