@RetiredWingMan, Personally I think a tablet is a bit of overkill in size. The new Samsung XCover 6 pro is a 6.6" screen, and with it it is bigger than any closed dedicated GPS device. If you consider a second phone to avoid putting your high-end daily phone on your handlebar there are multiple possibilities that cost way less then a Zumo. I a quite content with CAT S52 which I bargained a few years ago, but I hear they are having difficult times. To avoid cheap chinese stuff with questionable customer support I would give these a chance if I had to choose now:
- Nokia XR20
- Samsung Galaxy Xcover 6 pro or 7
since a lot of phones are waterproof by design nowadays, helped with a rugged case these would also do fine:
- Motorola Edge 40
- Google Pixel 5 or 6
If you are more adventurous than me, there is a whole plethora of brands like Blackview, Oukitel, Ruggear that can often be had for less then โฌ 200,00. After checking the waterproof box (IP-x8 at least) the next most important spec is the brightness (nits). Older Zumo's produce about 500 Nits at max, but nowadays that is considered to be not much. XT produces about 1200 Nits and the XT2 even more. Some modern phones can produce even more, but I would go for at least 800 to 1000 Nits if possible. That ensures readability in bright sunlight.
