Tech4o Traileader Jet

These watch navigation tools are worthless gimmicks. I didn't give it 0 stars because the time worked. However so do 5 dollar cheap throwaways. When you are hoping for readings for navigation in altitude or direction and your product is 400 ft off even when you have followed proper reference instructions. It says it's sunny when storming and that's after its several hours to calibrate.

Save your money, buy a compass and map and a gps. This watch is a usless and as dangerous as a false cairn.
