I am new to the forum and what brings me here is because I received a G-Shock GW7900B-1 for my 30th birthday on Tuesday (It is also the first watch I ever owned). I have always wanted a G-Shock since I was a freshmen in high school but never got around to buying one. And as I got older, more and more kids were wearing one, so it turned me off from the G-Shock.
Anyways, I was at the mall with my girlfriend a few weeks back to purchase a graduation gift for her sister, Baby G BGA 101-7B because she is going to be a nurse. I told me girlfriend I always wanted to get one of these G-Shock since I was a kid buy never got around to getting one, and now days with a clock on the cell phone, I didn’t really need it. But then I saw the GW7900B-1 with the moon data and tide graph which sparked my interest again. I am an avid angler and use the moon and tide data to help with fishing.
It has only been two days and still learning how to use the watch, but was wondering if anyone could guide me in reading the tide graph? Is the tide graph only for the ocean or will help with the river systems too? I live out in the West Coast, Sacramento, CA to be exact, if that could help me answer my question.
