I finally decided to go with pic related. I learned more about Casio models than I ever thought I would.
The 2500t has the 3-sensor verson 2 but even thought the 3500 has the version 3 sensor, it doesn't have moon/tide graph.
I was really thinking about the 6100y or the 7000 but I didn't want to spend $500+ on an adventure watch that admittedly looked better, but with similar functionality.
It was also about only $60 more than the 240b pathfinder. which didn't have the moon graph.
I'm using this for fishing, so I kind of wanted moon/tide info.
I may buy into others, especially the 91w for office use. Or maybe I'll just go full dw5600.
