The 76 CSx manual and web site never mention the tide charts and I did not find them easily. I wonder why? I routinely used them in my 76S and did not buy a 76CSx right away because I could not confirm that the tides were still built in. The plots are so superior to the 4 point tables. Am I the only one using them?
The sensitivity is wonderful. I use it in the house, under trees and in the rain. Never could do that with my 76S. I often use a Gilsson 3 foot remote antenna on my hat and I routinely get 12 satellites with most maxed out. Error listed is routinely under 10 feet.
I am a happy camper!
