Read a review of the TrailSeeker 80 Angled Spotter by BirdWatching Magazine below.

The TrailSeeker spotting scope series offers an amazing viewing experience in a rugged and durable rubber armored housing that is fully waterproof and Nitrogen filled. The optical system with proprietary XLT multi-coatings renders high resolution images with outstanding contrast while the dual focus mechanism allows you to get subjects in focus quickly and then fine tune the image.

Enhance the View

Large objective 80mm and 100mm models are extremely useful in the field both for all the additional light they allow into the optical system and in making the most of the dawn’s early or the twilight’s fading light.

Outdoor Adventures

Whether bird watching, hiking, camping, or just observing the scenery, the TrailSeeker Spotting Scope series in outdoor ready! Theese scopes’ robust, fully armored design protects them when out in the field and provides additional peace of mind that they’ll be ready when you need them.
