Good idea. I had a handheld trail gps for dirtbiking. I’ve since lost it. I can’t use my phone and usually leave it in the truck. They don’t like water or cold very muchI have a hand held GPS that will show time, speed, max speed, average speed, shows distance, etc., and mounts in a model specific holder that will mount on a round bar but works best on a ball mount. It's getting old, I've had it for several years, and it clamps onto a ball that mounts onto the handlebars of my ATV. This one also has an interchangeable cup holder available that will pivot so it's spill proof too. I'm sure that you can pick up a similar unit from a sporting goods/hunting store.
