I have a pair of B&L 10x42, fogproof, water proof, adjustable eyecups, and the biggest pieces of crap I have ever owned. They are 2 years old and seeing double, never actually been fog proof, and to top it all off I paid 299.00 for them and saw them in the paper a year later for 99.00. Also use a bino system and love that, my last trip outdoors I took my 7 years olds 19.00 Tasco's, ahhhhh. Next pair will be 10x Swarovski's.
