Hello, I live in Miami, I noticed the device Approach R10 was getting hot while I was practicing golf in my backyard, the actual temperature in Miami is 70 Fahrenheit, I played for 1 hour, so the question is, is it normal that the device gets hot? and should I cover the device with shadow? how long can I play outdoors with higher temperatures, summer in Miami is around 110 Fahrenheit, is this device strong enough for that?
