General information

Compact, reliable and sturdy, Levenhuk Karma PRO binoculars are a perfect choice for people who like to travel a lot, often go hiking and sometimes, along the way, find themselves in extreme situations and harsh conditions, where regular binoculars just would not do. The rugged shell of these binoculars protects the intricate optical system inside from any sudden impacts or moisture. The binoculars can be used by people wearing glasses.

• Water-resistant shells, embossed for the perfect grip;

• Central focusing and diopter adjustment mechanisms;
• Minimum close focus distance of only two meters;
• Adaptable to a tripod (except for Bx25, 1 Ox25; purchased separately).

The kit includes

Levenhuk Karma PRO binoculars, dust caps for eyepieces and objective lenses (except for Bx25, 1 Ox25), strap, pouch and optics cleaning wipe, user manual and warranty.

Focusing and diopter adjustment

Your left eye vision might be different from that of your right eye and you might need to adjust the diopter setting on one

• of the eyepieces. To do this, just follow this simple procedure:
• Look through your binoculars at a distant object; Close your right eye and rotate the central focusing wheel
• until the view is focused;
  Now, close your left eye and observe with your right. Slowly rotate the diopter adjustment ring on the right eyepiece until the view is focused again.
  Now that your binoculars are focused, you only need to use the central focusing wheel during observations.

Care and maintenance

Never, under any circumstance, look directly at the Sun, another bright source of light or at a laser through this device, as this may cause PERMANENT RETINAL DAMAGE and may lead to BLINDNESS. Take necessary precautions when using the device with children or others who have not read or who do not fully understood these instructions. Do not try to take the device apart on your own. For repairs of any kind, please contact your local specialized service center. Do not touch the optical surfaces with your fingers. You can use a soft napkin or a cleaning wipe, dipped in ether or absolute alcohol, to clean lenses. We recommend using special optics cleaning fluids from Levenhuk. Do not use any corrosive or acetone-based fluids to clean the optics. Abrasive particles, such as sand, should not be wiped off lenses, but instead blown off or brushed away with a soft brush. Do not apply excessive pressure when adjusting focus. Do not submerge. Protect the device from sudden impacts and excessive mechanical force. Store the device in a dry, cool place away from hazardous acids and other chemicals, away from heaters, open fire and other sources of high temperatures. Do not use the device for lengthy periods of time, or leave it unattended in direct sunlight. Always store the device in a special case. We recommend keeping the silicate gel pack, when included in the kit. During long storage, a thin white film may appear on the rubber armor. You can wipe it clean with a clean napkin.
