I have the nova sail 360 pro . I believe it is the newer version with the corrosion issues solved . One year in it works great , crew can easily set it and I can from the helm . The GPS speed is great to compare to the through the water speed for current . Did not use the distance to start much as we were getting to the start line a little late to set it up but it does work well. I really like that after the countdown timer stops it switches automatically to a selected race mode. It is at the mast and easy to read from everywhere , light comes on automatic and it is easy on batteries. Nice to have a bunch of instruments all combined in one .
