Product Description
Brunton 5005LM International Pocket Transit effectively reduces needle "dip" when professionals travel to different hemispheres. (Call us for the special balancing required for absolute precision in distant areas.) Powerful Alnico V magnets are mounted to a polished, cupped sapphire jewel bearing, allowing for smooth needle movement.
This International Brunton LM pocket transit is the most popular aluminum body version because it is waterproof and dust proof. It has the traditional machined aluminum compass body finished in a durable textured light gray enamel. Brass hinges and pivots are attached to the pocket transit by screws. The Brunton international pocket transit model 5005LM scaled in quad 0-90 degrees, dust and waterproof, aluminum metal case, and comes with leather pouch.
Adjustable needle locking mechanism with two positions: Unlocked - releases the needle for azimuth readings. Locked - momentary release of the needle for strike measurements by pressing and holding the release mechanism, then lock the needle for reading by releasing the mechanism.

Frequently Asked Questions
What is the accuracy of the Brunton Pocket Transit?
The Brunton Pocket Transit provides 1° resolution. All Brunton Pocket Transits are hand-built and pass a rigorous 100% quality assurance inspection for 1/2° accuracy, both vertically and horizontally.
How do I open my pocket transit?
Rotate the pocket transit so the flat cover side faces up, and the small window is positioned away from you. Unlatch the cover from the base of the transit.
How can I protect my pocket transit mirror?
To protect the mirror while in storage, Brunton recommends placing the pocket transit in the case with the base against the closing snap.
Why are E & W switched on the bottom plate?
The Brunton Pocket Transit is a direct reading compass. The needle points directly to the bearing on the azimuth ring, which is graduated counter-clockwise. There two ways to take a direct reading: 1) point the large sight toward the object, and read the bearing where the 'N' or white tip of the needle points to the azimuth ring, or 2) point the small sight toward the object and read the bearing where the 'S' or black tip of the needle points to the azimuth ring. If the bearing of the object is 45° from true north, for example, the needle will point between N and E on the bottom plate. The bearing will be the same using either method. Try it!
Can I use a transit in different countries?
Yes, you can. If your location is near, or south of the balance lines, the needle on your Brunton Pocket Transit requires special balancing. Contact ASD if you are uncertain or your transit requires special balancing.
What are some differences between Brunton's Pocket Transits?
The Conventional/Commercial aluminum body is not waterproof, while the International aluminum body, the GEO billeted aluminum body, and the ComPro composite (plastic) body are waterproof. Both the Conventional and the International have the long bar, Alnico II magnet. The ComPro and GEO have a round NdFeB rare earth magnet which resists demagnetization better than the Alnico II magnet. The NdFeB magnet also settles slightly faster because the magnet is stronger. The International can be used in a wider range of countries because needle has a lower center of gravity, which reduces needle 'dip.' It is easier to read a bearing on the ComPro & GEO because of the way the north and south tip of the needle is marked (labeled 'N' & 'S' plus a line) for precise measurement. The International and the Conventional have a 'North' pointing needle which is solid white. The GEO incorporates two brand new features. It has a hinge inclinometer with accuracy to 2°. Now a user can sight dip and dip direction at the same time. Also, the hinge is much more durable and can withstand hard use. Brunton offers a lifetime warranty on the GEO, where all of the other Pocket Transits have a 1-year warranty.
