Simple
tide is based on the average tidal cycle of 12 hours 25 minutes and 14
seconds between major tide events (hi to hi or low to low). For best
tide prediction accuracy check and reset your tide mode periodically.
This interval is based only on the rotation of the moon, and provides a reliable reference FOR YOUR LOCAL BEACH'S TIDE.
From the mode press "reset" pusher to cycle through the tide of the day.
