When I was a boy, my uncle let me borrow his B+L Discoverer. I used this scope to spot my hit on paper . It’s a straight tube refracting telescope of the kind that looks like a classic telescope. In fact I used to see the rings of Saturn for the first time.
Last year, I indulged in a little nostalgia when I purchased a 1980’s vintage B+L Discoverer spotting scope on Ebay. This 15-60×60 spotting scope was made by Bausch and Lomb, a brand best known today as a maker of contact lenses but back in the 1980’s, B+L was better known as a maker of military grade optics. B+L made binoculars and target scopes for US Army tanks and planes in the WWII, and invented RayBan sunglasses for bomber pilots.
The Discoverer dwarfs most modern 60mm spotting scopes. It is over 17″ long and weighs 3lbs due to its all metal tube construction and glass. Modern spotting scopes typically utilize a prism to bend the light and make the overall length, shorter. Most modern scopes are far lighter using more plastic parts. And most importantly, modern ED glass has higher light throughput, specialized coatings to reduce chromatic aberrations.
Most modern spotters over $250 in the 60x class will offer better image quality due to advancements in computerized glass fabrication and optical coatings. But compared to budget scopes, the Discoverer can still hold its own with superior sharpness and detail. If you’re lucky, you can still find this scope on Ebay, estate sales or garage sale for under a $100 (mint condition in box models go for much more). Just be sure you give the glass and the body a good inspection.
