I just use the default then memorize the displayed data , water depth at the present water level, time of day, barometric pressure, wind speed, cover type and wind speed. Of course, I can't remember any of it, but this method seems to be working about as good as any other scheme I've come up with.

I acutally have a set of waypoints labeled - WC-21a-1624-z1- 1 through 16. Got no idea what it means, but I'm pretty sure it's important and fish it every time I'm on the lake. Sooner or later, there will be fish on it and I'll be able to decipher the code. When I do, I'll carve a Roseta stone and mount it next to the Humminbird. Then I'll be unstopable.
