"The GPO SPECTRA™ is a pleasure to use. The build quality and features are spot on. Especially the optional ballistic turret and the adjustment lever for the zoom ring are practical features. In combination with clip-on devices, the slim optic plays to its strengths."

"The GPO SPECTRA™ 8x 1.6–13x44i is a riflescope that leaves little to be desired and meets all the requirements of modern hunting. You don't really expect such performance data and high-quality workmanship in this price category. It was always a pleasure to hunt with this scope and have the confidence that I could rely on the optics. The scope always brought a happy grin to my face when I could use the full magnification range – for example, on driven hunts or during the roe deer rut, when it's never clear beforehand whether the game will appear at 10 m or 100 m."

"In designing the new SPECTRA™ Pistol DOT, GPO paid particular attention to the requirements of ambitious and professional pistol shooters. [...] All this makes the new SPECTRA™ Pistol DOT an excellent optical sight for anyone who depends on rapid target acquisition in sports, hunting, or on duty. [...] Considering the features and especially the included Picatinny mount, we also believe this is a very affordable and more than fair offer that you should definitely take a closer look at."

"The SPECTRA™ 8x 1.6-13x44i is almost the famous jack-of-all-trades and the ideal riflescope for the modern hunter who pursues wild boar at night with a clip-on device and during the day on driven hunts. It is also perfectly equipped for an occasional mountain hunt or for stalking roebuck during the rut. For a clip-on device, the short construction and reinforced housing are ideal. The illuminated reticle is top-class, and the optional ballistic turret also makes the scope suitable for long-range shots. Conclusion: GPO is known for optics with a good price-performance ratio, and this also applies to the SPECTRA™ 8x 1.6-13x44i."

"Partnering with German Precision Optics (GPO) has redefined my hunting experience through their exceptional engineering and reliability. I have primarily relied on the SPECTRA™ 2-16x50i mounted on Sako 90 Peak, while the SPECTRA™ 1-8x24i has proven to be a perfect match for my Mauser 25. Both scopes feature low profile turrets that easily convert to a ballistic turret system. This upgrade includes six clear markings for distances from 100 to 600 meters, supported by a dependable zero stop. RANGEGUIDE™ 3200 binoculars with included rangefinder make ranging game easy. The glass quality is great and the mechanics track true. For fast-paced driven hunts, the SPECTRA™ Dot 1x20 remains my go-to for rapid, precise target acquisition."
