    Regal F 100 mm spotting scope

    I am interested in the Regal 100 mm spotting scope. I read Frank's comments about using a Pentax XW 20mm with one the smaller regal scopes. If I remember correctly, he said he received a 10% cutoff at the bottom of the view when using the XW 20mm eyepiece. This concerns me because I use the...

    Angled Rangefinder

    Why an Angled Rangefinder? I enjoy optical exploring of nature and urban architecture. This should come as no surprise to those who read my posts. The idea of a rangefinder occurred to me one day when I wanted to measure the height of the large pine and oak trees behind my house, to...

    7x binoculars increasing in popularity?

    Are 7x binoculars becoming more popular again? If more models, higher prices, and out of stock inventories are any indications, then the 7x may be challenging the 8x. After reading an interesting thread on “8x vs 7x for forest birding,” I decided to check 7x models at a popular online optics...

In his book, Pete Dunne on bird watching: The how-to, where-to, and when-to of birding (2003), Dunne states...
