Use of Compass
How to use the Analog Compass
Read the bearing to which you are pointing the binocular.
Line up the object to which you would like to get the bearing
on the vertical scale and read the bearing beneath.
For analog compass models the bearing is illuminated by daylight
and can be illuminated by a touch of the button on the side
of the compass at night (7x50 models).
How to use the Digital Compass
ON/OFF: Press ON/M bar to turn compass on. Display will run through a warm-up cycle and display 'CAL' (calculating).
After two seconds, the display will show the current setting, e.g. 'd 0' or 'd 10' (see below). The binocular will
turn itself off after 10 seconds of non-use.
Bearings: Press bearing bar: display shows instant bearing. Hold bearing bar down: display shows 4x per second
average while you hold the bar down.
Memory: To enter bearings: Sight the binocular on an object and take the bearing, allow the binocular to turn off. The
bearing will be automatically saved and will be stored until next usage. When turning the binocular compass on
this last bearing will re-appear. To record another bearing, simply reset this process.
Declination: The difference of the angle between true north and magnetic north is called declination. This can vary by
your position on the earth and on the compass orientation towards the magnetic north. This declination
can be adjusted on the digital compass up to +/- 40 degrees maximum. The declination can be found on all
marine charts and enhanced topographic maps. Please also be aware of annual changes in declination.
