Here's what others have to say...

This particular 10 X 50 Brunton is about...

This particular 10 X 50 Brunton is about 1/2 price of the Brunton Externa full sixe 11x45. Why is that??

Best Answer

The Externa are a much higher grade and thus the higher price. The Externa has a composite shell material and Bak-4 prism glass for a crisper view. Depending on the use these should work just fine.
