New Rangefinding Binoculars from German Precision Optics (GPO) Set a New Standard

RICHMOND, Va. (Jan. 17, 2024) — In its continued effort to provide its customers with cutting-edge products, German Precision Optics once again sets the standard in precision rangefinding binoculars with the expansion of the popular RANGEGUIDE lineup, the new RANGEGUIDE™ 8×40 and RANGEGUIDE™ 10×40. Measuring just 5.6 inches tall and weighing a scant 25 and 26 ounces, respectively, these new rangefinding binoculars are the smallest and most compact premium mid-sized products in the industry, only slightly larger than the RANGEGUIDE 8×32 and 10×32. These new RANGEGUIDEs now complete the company’s rangefinding binocular lineup that includes an 8×32, 10×32, 8×40, 10×40, 8×50, and 10×50, which is the industry’s best brand lineup in this category.

Like all the GPO RANGEGUIDEs, the new 40s feature a magnesium frame that decreases the weight and increases the strength of the product. The eye-safe Class 1 laser produces a lightning-fast 0.25-second response time that has been enhanced to reach targets up to 3500 yards and has true-range angle technology that calculates the proper distance to the target after measuring the angle to the target, giving you a precise inclination/declination compensation reading. Scan mode provides three readings per second via its red OLED display that offers nine adjustable brightness levels and operates with manual or automatic brightness functionality. And for those who are also long-range rifle shooters, the RANGEGUIDE 40s measure ambient temperature in Fahrenheit and Celsius, humidity, and air pressure to assist with long-range shot placement. The display provides the line-of-sight distance and the user’s adjusted distance, angle, or temperature choice.

Coupled with the GPObright™ high-transmission lens coatings, the new RANGEGUIDE’s double-HD laminated 40mm objective lenses are exceptionally beneficial for transmitting light in the twilight hours. These premium lenses maximize the optical image’s brightness, sharpness, and resolution, something not typical in a rangefinding binocular. The spacious field of view is 375’ and 330’ (8×40 or 10×40) at 1,000 yards, and eye relief is 18mm and 16mm respectively. The new RANGEGUIDE 40s also features a diopter focus and red display focus adjustments on both the left and right sides of the ocular tube and utilizes GPO’s premium cut-brass-geared focus-wheel system for a tight, consistent turning radius without any center focus wheel free play. The entire body is protected with an armor coating that makes it tough enough to use in any environment. 

“Binoculars with 40mm objective lenses have long been the most popular size for hunters worldwide,” said Mike Jensen, GPO, USA’s owner and CEO. “These two premium rangefinding binoculars are the perfect fit between GPO’s 8×32 and 10×32, and 8×50 and 10×50, RANGEGUIDE™ units, rounding out GPO’s lineup in this category as we continue to set the industry standard for both high quality and affordability. Now hunters can pack a lightweight and compact unit yet will not compromise on optical quality, the ability to see the target in low light situations, or the speed and accuracy of the laser rangefinder – all at a price lower than other comparable premium brands.”

GPO’s best-in-the-business lifetime warranty backs all GPO RANGEGUIDE™ rangefinding binoculars. This portfolio of products has also been price repositioned, lowering the existing RANGEGUIDE prices to make all rangefinding binoculars more affordable for the serious outdoorsman.
