For what is worth. I had a Standard Horizon in a kit bag that I drove over with the jeep. OOPS. It still worked but could not read the screen. Bought another one and the knob broke apart while stored in my kit bag on the boat. It is a good radio with a very cheep knob. I keep vest, hat, gloves, sailing tools etc. in the kit bag for when I sail another boat-I just grab the bag and go.
