Brunton Compro Transit (F-5008-050)

Technical Specification

• Azimuth Dial – 1x 0-360 degrees on dial

• Unique dual axis hollow hinge allows for easy and intuitive measurements of any line or plane.

• The lid rotates 360˚ around both axes, making measurements possible for any surface including overhangs. The lid can extend or create the measurement surface itself.

• The default orientation of compass North makes this the only transit in the world that can measure strike & dip simultaneously. A simple rotation of the azimuth ring also allows simultaneous measurement of dip angle & dip direction if that is preferred.

• A secondary axis of rotation and lid protractor allows simultaneous measurement of trend & plunge.

• The hollow hinge/sighting tube allows for direct horizontal and vertical sighting measurements.

• Hinge dial enables dip angle measurements and also serves as a versatile protractor.

• Excellent contact and sighting measurement capabilities.

• Dual long-level bubbles allow the user to level the compass from the sides and bottom.

• The flat bottom allows for easier dip angle and dip azimuth measurements at low angles.

• The needle can be set to lock automatically, allowing for accurate readings.

• The precision NdFeB disc magnet provides very accurate readings and resists demagnetization.

• Our magnetic needle can be balanced for use almost anywhere in the world .

• Induction dampening makes for a quick-settling needle.

• A sapphire jewel bearing allows for smooth needle movement throughout the life of the instrument.

• The needle lock button can lock or free the needle, depending on the model.

• The internal components are sealed with an O-ring for improved resistance to dust and water.

• Each comes with a protective leather case.

• Made in the USA

There may be a few weeks lead time for this product. Please inform if you need specific balancing.
