Here’s another tip that I recently discovered. I went on a multi-day kayak trip lately that involved some long open water crossings requiring a lot of compass use. Maybe my eyes are getting bad, but I found it really hard to read my compass on this trip through the beaded water on the compass globe. After this trip I tried coating my compass globe with Rain-ex and it helped a lot, making it much easier to read the compass on the water. In the future I will always coat my compass globe with some rain-ex prior to a trip requiring its use.
