Astromart Review: Orion Explorer 25x100 Large-Aperture Binocular
Joplin Motisher on Astromart takes a 'quick look' at the Orion Explorer 25x100 Binoculars and comments favorably on its specifications but has a reservation on the weight of the device. 'I didnt have a chance to do many direct comparisons with my 16x80s but it is very safe to say that the 25x100s were a substantial improvement in every department except weight. At 10 lbs for the pair these are very heavy binoculars that require a heavy duty mounting for comfortable use. I was quite impressed by the build quality of these binoculars, the individual eyepiece focusers are smooth, the inter-occular adjustment has just enough stiffness, the optical coatings reflect very little light. The optical alignment of this pair was perfect as far as I could tell. The apparent field of view is about 60 degrees and there is plenty of eye relief for glasses.'
