APM 20x80mm MS Binocular (Nitrogen Filled)

The high quality APM MS binoculars designed specifically for outdoor use, the MS Binocular series are fully nitrogen waterproof and can be used in the rain or left unprotected on a tripod during showers without the worry of water penetration.

In addition to waterproofing, the binoculars are protected with durable natural rubber covering.

Featuring a high specification for porro prism optical system, the clarity and field of view derived from the 16×80 makes it an excellent choice for astronomy, while the higher magnification 20×80 and 25×80 are geared more toward long range terrestrial observation and specialist outdoor applications such as aircraft observation. All three models provide long eye relief and deliver full field of view with or without spectacles.

Used either as hand held instruments or using a photo or video tripod especially for the higher magnifications.

Delivery contains:

  • Binocular
  • Carry Case
  • Metal Tripod Adapters
