Sighting system
PA (prismatic) model has the 10x prismatic magnification system on top of the housing, making it extremely easy to obtain accurate readings even in dark conditions.

Clinometer card
The clinometer card has a precision scale and top scale for direct readings from the top of the capsule. It has a sapphire jewel bearing for friction-free movement of the card, so readings are fast and accurate.

Housing
Anti-static liquid-filled capsule for optimal dampening of card movement.

Accuracy
Precision sighting +/-0.25° from true angle. Direct reading (at lubber line from top of housing) +/-1°.

Compact and light
Just 75 x 53 x 16 mm, weight 120g.

Heightmeter scales
1015/1025 models have height scales for distances 10,15, 20 and 25m to the object. By doubling or halving the height reading, it can easily be used at 5, 10, 15, 20, 25, 30, 40 and 50 metres distance from the object.
