Excerpt: I use this monocular for telephoto camera picture acquisition shots. It works great and the compass allows me to share observations with friends nearby while I grab the camera . It also has a ranging reticle to allow distance estimations. I haven't noticed any eye fatigue from extended use either. For the price, not bad. The ITAR designation is a little ridiculous, since this was made in China.
Pros: Accurate Ranging, Don't Need Batteries, Easy To Use, Nice Nylon Carry Case, Very Clear Lense
Excerpt: Best mid-range binocular for a great price! I have been using the Celestron TrailSeeker 8x42 for a few months now. I use them primarily for birding and bird watching, but watch other wildlife with them as well.
Summary: This little monocular is quite big in size. Have a 42mm objective with 8X magnification. Contrast is quite good for this magnification and great FOV as well. Chromatic aberation minimal. Image is sharp & crisp. But it carries quite a heavy price for this small wonder.
Summary: The field of view is very relaxing to the eye and the optics are bright and precise. I am able to indentify electronic devices by type, on my towers, with this monocular due to its clarity. The compass allows me to check the positioning of antennas on towers.
