Zeiss Terra 10x42 Binocular Product Info The 10x42 Terra ED Binocular from Zeiss combines SCHOTT ED glass elements and a compact weather-sealed housing to create a multi-purpose optic that delivers the image quality and streamlined silhouette worthy of the Carl Zeiss name. The Terra ED is the third binocular line in Zeiss' Sporting Optics catalogue, accompanying their popular Conquest and legendary Victory binoculars under the big top. Zeiss engineers designed the Terra ED for birders and hunters seeking a budget-friendly set of glasses that do not sacrifice twilight performance or functionality. At the core of Terra ED series optics are fully multicoated SCHOTT ED glass lenses designed to maximize light transmission and render contrast-rich images. Thanks to a space-saving Schmidt-Pechan roof prism design and lightweight composite housing, this binocular weighs less than 2 lbs. Complementing the high-transmission optical path and modest form factor, the Terra ED has a nitrogen-filled housing that provides fogproof performance and submersion tightness to a depth of approximately 3 ft, preparing these binoculars for almost any outdoor observation. This configuration of the Terra ED binocular features 10x magnification and an immersive 60° apparent viewing angle. These features, in addition to the 14mm eye relief, equip the 10x42 optic for comfortable glassing. These glasses also boast the ability to focus down to less than 6 ft, allowing observers to get up close to the bird or other nearby subject of interest.

Minox APO HG 10x43 BR Binocular Product Info Representing the pinnacle of their optical prowess, the APO HG binoculars from Minox deliver a remarkably accurate and well detailed image. The glass is manufactured by Schott AG - the eyepieces are graced with aspheric elements, while the rest of the optical stack features fluoride glass ED lenses with apochromatic properties. As a result - the APO HG 10x43 Asph. delivers exceptional optical performance. Across the entire field of view - the APO HG offers enhanced contrast and sharpness from the center to its edge. The technologically advanced APO HGs also feature a cornucopia of multicoating technology. The phase-corrected BAK4 roof prisms sport Minobright coatings for enhanced light transmission. The lenses lay claim to no fewer than 21 layers of with M* multicoating to increase their efficiency, while the external surfaces are treated with MINOTEC multicoating to repel dust, water, and soiling. These optical treatments ensure maximum clarity, light throughput, color-rendition, edge-to-edge sharpness, and the longevity of the optic's critical external surfaces. The APO HG is built around a rigid, tough, and lightweight magnesium alloy housing that offers a significant reduction in weight, a sleek profile, and an excellent platform for a precision optical system. Argon gas purging and a rubber-armored exterior ensure optimum performance and handling regardless of the climate. An enhanced center-focus design features Minox's innovative QCF (Q uick C lose F ocus) system. Precise long-distance and rapid close-focusing is easily managed with a single turn of the cross-knurled focusing-knob. A thoughtful range-finding scale on the knob allows viewers to take distance readings at a glance. Features: Optical Performance BAK4 Prisms optimize light transmission Aspherical lens elements: enhanced sharpness Fluoride ED glass lenses: apochromatic performance Full M* multicoating delivers 92% light transmission MINOTEC multicoating repels dust, water, dirt, soiling Minobright prism coating technology enhances efficiency, resolution, contrast Construction Details Argon purged housing is water and fogproof Tactile rubber armoring provides a secure slip-resistant grip.

Specifications: Track width: 15mm Color: As shown Size(Length x Width): appr. 10 x 7cm Power: 2 x AA battery Voltage: 3V The assembly steps: Step 1: Welding circuit Electric welding part is simpler, welding sequence according to the principle of component level from low to high, the first welding eight resistance, is important to use multimeter to confirm resistance is correct, D4, D5 R13 R14 can temporarily not welding, integrated circuit chips can temporarily not inserted Step 2: Mechanical assembly The red line is connected to the 3V positive power supply, the yellow line grounding, excess wire can be used for motor wire. Step 3: The installation of a photoelectric circuit Photosensitive resistance and light-emitting diodes (note polarity) is reverse-mounted on the PCB, and the ground distance is about 5 mm, both photosensitive resistance and light-emitting diodes are 5 mm distance. Finally, you can power test. Step 4: Vehicle debugging The right direction is along the universal wheel direction, if you press and hold the left photoresistor, the wheels on the right side of the car should be rotated. Press and hold the right photoresistor, the wheels on the left side of the car should be rotated, if the car driving back, can also exchange the wiring of two motors, if the one side normal and the other side back up, as long as you can swap wiring of back side.
