A little gem!

A nice big, bright and clear view. Better overall than it's price would suggest. The nice case has a belt loop, so this little guy will be with me often. My primary binoculars are 10x32 and 10x42, but this TB ii 8x25 has it's place too. Truly a compact, light weight bin whether for backyard, in the woods or at concerts.

It is a small and portable binocular that can be carried in a pocket of a car's center console. Image quality is decent and definitely worth its price.
