So on a Casio that has tide graphs, do you have to enter the first high tide info every day you want to read the tide graph or does it take the info once and is reasonably accurate for "a while"?
Full disclosure - I don't really use the tide graph function but I DO want to understand it on my Pathfinder PAW-1500.
So today the first high tide is X AM per published local tide tables. I enter the tide graph function and update that time so, for the rest of the day, the watch will show the tides properly for my location (Southern California.) But what about tomorrow? The tides are generally close to what they were the day before so the graph is not going to be horribly off but do I have to enter the high tide every day to have it be more than generally close? If not, how long can I go before updating the time?
The manual does not really say you can set it once and forget it but it also doesn't say you have to update it every day. So I was wondering what it is.
Anyone know for sure?
