I see both sides useful. If you live down south, use the cam. If you live up north, use Clearwater sensor.
I have found the Clearwater sensor to be quite useful when hunting a sea breeze up this way. It is a pretty damn good indicator of what is happening out there as far as rideable wind or not.

Less addvertisement and in knots. Same gobalee goo however. :smile::smile::smile:
I do like to use the sensors to see if wind is on the increase or decrease. I use that info a ton when deciding to go or not.
Whatever works, but I definately don't consider Ikite or sailflow to be useless. Take what works and leave the rest.
