Celestron 10x32 TrailSeeker ED Binocular


Designed as your go-to multipurpose outdoor optic, the Celestron 10x32 TrailSeeker ED Binoculars features a suite of technologies and design features that will make it an essential part of your kit whether you're hunting, birding, hiking, or sightseeing.


Broadband anti-reflection fully multicoated high-performance extra-low dispersion glass deliver crisp, true-color images of breathtaking landscapes, vistas, or cityscapes. Phase-corrected and dielectric-coated BAK4 roof prisms maximize light transmission through the prism system, limiting internal diffraction and interference and improving image resolution and contrast. The 32mm objectives keep the overall form factor small so you can easily carry the binocular all day on the trail, in the field, or when sightseeing around the world. Combining all these optical features produce crisp and sharp high-contrast, wide-angle views with accurate color across the entire visible spectrum with limited distortion, especially at the edges.

Complementing its optical performance is a lightweight magnesium housing that is nitrogen filled and O-ring sealed to make it waterproof and resistant to internal fogging when you move through extreme changes in temperature or environmental conditions. The body features an ergonomic design with rubber armor and strategically placed texture that offers a secure hold and a pleasant handling experience, with the large center focusing knob providing smooth adjustments. To help you with focusing and correcting for dioptric differences, the focus knob and the diopter ring are knurled and can be easily adjusted even when wearing gloves. Ideal for fast glassing on the go, the Trailseeker ED comes with tethered caps that won't get lost when you're out and about and a shoulder harness that eliminates strain on your neck and prevents it from swaying and swinging if you need to climb over rough and rocky terrain.


Optical Performance

  • High 10x magnification allows for detailed observation of distant subjects
  • 32mm objective lenses have the light-gathering ability close to a full-size 42mm model with the comfortable form factor like a compact
  • Roof prism light path keeps the optical tubes thin for easier handling and packing
  • BAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortion
  • Phase-corrected prism coatings reduce internal interference to improve contrast and resolution
  • Highly reflective dielectric prism coatings maximize light transmission through the prism system
  • Extra-low dispersion (ED) glass lenses offer true color representation, with improved clarity, contrast, and sharpness across the entire field of view
  • Broadband anti-reflection fully multicoated optics enhance light transmission for brighter and sharper views with enhanced contrast across the entire visible spectrum
  • Wide 62° apparent angle of view limits the appearance of the distracting hand shake often experienced when holding high-power optics
  • Spacious 326-foot field of view at 1000 yards


Use and Handling

  • Short closed-bridge configuration provides a stable platform for the internal focusing mechanism
  • Large knurled focus wheel is easy to manipulate in cold and wet weather or when wearing gloves
  • ±3 diopter adjustment on the right ocular enables precise focusing, even for users who normally wear corrective lenses
  • Twist-up rubber eye cups for comfortable viewing with or without eyewear
  • Integrated 1/4"-20 socket on front of bridge hinge enables the use of an optional tripod adapter for hands-free viewing
  • 14.4mm eye relief
  • 3.2mm exit pupil


Construction Details

  • Short bridge design offers more surface area to grip, despite the short length, for improved handling
  • Strong and lightweight magnesium housing
  • Slip-resistant armor with textured palm pads improve grip security
  • Nitrogen filled and O-ring sealed to an IPX7 rating: Waterproof to 3.3' for 30 minutes and resistant to internal fogging
  • Tethered one-piece ocular rainguard and objective lens covers protect the lens surfaces without the fear of losing them when using the binocular
  • Binocular harness shifts the weight from the neck to shoulders for more comfortable carrying while limiting swing and sway when moving over uneven ground
  • Compact design is less than 5" long
