We didn't award a Great Buy in the Full-Size Binoculars category, but Maven's B5 easily won Editor's Choice for its excellent glass, wonderful balance, and responsive controls. The 15x56 (also available in an 18x56) is big and heavy, but the metal-alloy chassis is durable, the Abbe-Koenig prism gives the exterior dimensions a hand-gripping curve, and the diopter and focus are tack-sharp. The eyecups, an attribute that has a huge bearing on user comfort, are pleasingly positive. Big 15x56 binos are hard to balance, but the Maven settles on a tripod nicely. Yes, it's pricey, but the B5 is an investment that should survive years of hard use.
