Review on 📻 Zerone External S Meter SWR Power Meter for Yae su FT-857 FT-897 - Accurate Receive Display Meter for Enhanced Performance by Marcus Curry

This is an amazing gauge. There is still room for improvement. The one I got had to be calibrated for zero and full scale, which didn't really matter until I tried to adjust the full scale setting and couldn't find the potentiometer. It was folded back during assembly and I had to remove the cover to bend it to be able to adjust it. There are no conditions for mobile use and no conditions for lighting. Overall this is a great counter, I will most likely buy a second one as a backup.
