Sarge:
I have experience with both of these, first the Monarch 5, 8x42 and currently the Monarch
7, 10x42. I like both of these, very sharp, and bright.
I gave the M5 8x42 away to a friend, he had his choice between the M5, and the Zeiss
Terra 8x42, and he went with the Nikon.
The wider FOV of the M7 is nice, any coatings changes between these is not apparent, and it is a great choice.
I recommend either one. Typical Nikon, nice fit and finish, smooth focuser, I like that.
