I currently have a Silva Starter http://www.silvausa.com/baseplate.html in my emergency kit. Actually an older version of this same basic model. And a Brunton 9020G as my main compass http://www.brunton.com/product.php?id=116

I was looking to learn how to use and practice with a lensatic. No real need ... just because! As I understand it, orientation is best done with an orientation baseplate compass. But I still think the lensatics are cool looking and want to try one out anyway. Lots of cheaper lensatic models at REI and LLbean, etc. About half the price of the one in the link I previously posted, but probably not as good. Maybe even in the "trash" category. I don't know.
