Q: 1. what is the difference between Bushnell Legacy WP and Bushnell H20Porro binoculars?

A: I asked the same when I was ordering the 8x42 binoculars to donate to the Environmental Education program a the Cloud Forest School in Monteverde Costa Rica. I ended up with the Legacy WP's . Although they seemed well made, they were too large, too heavy, and too hard to focus...not only to be used with K-11 students but also for me. B+H Photo was excellent about processing the return. I purchased the 8x25 compact H2O binocs instead.Just returned from delivering them to the Cloud Forest School where they are already being used with ease.

Q: 2. What is the inter-pupillary distance for these binoculars? This is a critical spec and it is missing from the displayed specs.

A: Most binoculars that are double hinged like the Pentax 8x25 A-Series AD WP Compact Binoculars BH #PE8X25ADWP • MFR #62881 do not list the inter-pupillary distance. I did find some info on the web. The IPD for the Pentax AD 9x32 is 55mm to 75mm.
