I like the CR5 model. It's about a half inch smaller than the CR2 so a little less accurate but the slight reduction in size allows it to fit in a lot more pockets & not just the ones on uniform shirts. Quite accurate enough though - I passed Oz both IR exams (as it was then), Oz SCPL/ATPL exams, US ATPL exam & UK ATPL exams using it.
