BARSKA BC160 Rangefinder Compass
Product Information
The BC160 is a device equipped with an internal rangefinder and directional compass reticle. It is designed to provide accurate measurements of distance and object size.
The internal rangefinder uses a scale reading to calculate the distance or size of an object. The rangefinder scale reading should be obtained from the device’s display.
The directional compass reticle helps in determining the direction while using the rangefinder feature.
Product Usage Instructions
How to Measure Distance:
- Determine the size of the object you want to measure.
- Obtain the rangefinder scale reading from the device’s display.
- Calculate the distance using the following formula:
Distance = 100 x Object Size / Rangefinder Scale Reading
How to Measure Object Size:
- Determine the distance to the object you want to measure.
- Obtain the rangefinder scale reading from the device’s display.
- Calculate the object size using the following formula:
Object Size = Distance x Rangefinder Scale Reading / 100
Note: Make sure to input the correct values and units (e.g.,meters, inches) into the formulas for accurate results.
HOW TO USE INTERNAL RANGEFINDER AND DIRECTIONAL COMPASS RETICLE
INSTRUCTION
To use the rangefinder scale, you will need to know either (1) the size or (2) the distance of the object. When the size of the object is known, the rangefinder scale indicates the distance to the object. When the distance to the object is known, the rangefinder scale tells you its size. Each mark on the vertical scale has a value of 5 MIL (1 MIL is equivalent to an angle that can determine an object one meter in height at a distance of 1000 meters.) Therefore, if a navigation chart gives the height of an object, by sighting on it and counting the number of MILs, you can determine how far away the object is. The horizontal scale should be aligned with the base of the object that you are sighting on. The increments on the horizontal scale can be used to determine the distance to the object if the width of the object is known and calculated using the formula.

- USING THE DIRECTIONAL COMPASS
The compass scale is in one degree increments. It is aligned with the vertical range finding scale. North is represented as 0˚, East as 90˚, South as 180˚ and West as 270˚. When using the compass, bear in mind the local variation between magnetic North and true North.
