15X42 Pre-focus Flat-fielding Stabilizer Binocular Telescope FOV4.3 IP67 Waterproof for Bird Watching/Bee Finding

Introduction:
- Built-in special prism structure, combined with high-precision electronic gyroscope, when sensing the tilt of the telescope, millisecond level reverse compensation is immediately activated to keep the prism stable and achieve ±3° mainstream seismic correction capability, effectively suppressing shaking when held. No matter how it shakes or bumps, when the anti shake switch is turned on, the screen can remain stable and steady.
- 15X high magnification viewing, no need for tripod or gimbal, anytime, anywhere viewing, high magnification anti shake, making shooting more stable.
- Global scene adaptation, suitable for diverse usage environments such as rescue, astronomical observation, natural bird watching, cultural performances, patrol, etc. It can withstand extreme temperature differences of -20°C to 55°C, ensuring stable use in various environments.
- For LANTHANIDE glass ED optical lenses, equipped with pre-focus ED micro flat field and RS-BRIT 2.0 coating, it has a comprehensive multi-layer 10 nanometer coating.
- The pre-focus flat-fielding technology expands the effective and clear imaging range, with uniform transitions at all four corners of the field of view and less deformation of lines.
- Wide field visual enjoyment, allowing you to have a wider field of view, 21MM big eye cup, no eyelash sticking, no eye pressure, no black shadow on the eyes.
- Ergonomic design, conforms to the shape of the hand, provides a more comfortable grip, and is not tiring to use for a long time.
- Two AAA batteries (not included) provide about 16 hours of continuous stable observation, and are equipped with an automatic power-off function that automatically shuts off the power after about 30 minutes of inactivity.
- The mirror body is IP67 dustproof and waterproof, the battery compartment is IPX4 waterproof, not easily affected by weather changes, and supports all-weather use.
