Never seen one in action. Have been a couple of threads in electronics forum about them. Seen a couple bought then sold pretty quick. Biggest complaint seemed to be visibility on these units. Especially in sun. That's why I didn't recommend it. It is a good price for a unit that does what it does. A sun shield might really help it. I'm just at the age where color really helps me. I have a monochrome unit hooked to my trolling motor and have a hard time seeing it at times.
