Brunton Baseplate & Orienteering Compass Range

Brunton compasses have been in the market since 1894 and are made in the USA. 

Let's start with the simplest model.


Brunton TruArc 10 Compass

Brunton TruArc 10

Explorers can depend on this high precision, mirrorless baseplate compass. A full set of navigation features and romer scales offer seamless GPS integration. In case you are more familiar with the Suunto range of compasses, the closest equivalent would be the Suunto M3.

 

Specifications:

  •   Dimensions: 5.2” x 2.8” x 0.5” | 13.2 x 7.1 x 1.2cm
  •   Weight: 1.7 oz | 48 g
  •   Resolution: 1˚
Features:
  • TruArc™ Global Needle tilts up to 20˚ for balanced use world wide
  • Tool-free declination adjustment is simple and fast to orient magnetic north to true north
  • Meridian lines on vial assist during pre-trip planning when aligning with map grid lines
  • Reversible inch/millimeter scale for accurate and effective map work
  • Romer scales provide maximum accuracy of latitude and longitude for easy integration with handheld GPS unit
  • Brunton EverNorth Magnet resists demagnetization over time
  • Magnified readout provides highest degree of accuracy without compromising readability
  • Double-gauge, ergonomic baseplate is durable and comfortable in hand 
  • High visibility cling for enhanced performance in low light; can be removed to facilitate map use
  • 1˚ resolution azimuth ring provides precise readings

 

Now moving on to the Mirror Compass options and comparing the Brunton range to the familiar Suunto range:

The Brunton Geo Lite is meant to be an affordable geologic transit. It's essentially a combination of the Brunton Compro Transit and Brunton TruArc 15 Compass, but a lighter version.

With the leveling bubble and hinge clinometer on the Geo Lite, it can take measurements such as strike and dip, dip and dip direction, and trend and plunge, which the more expensive Brunton transits can do. Whereas the Suunto MC-2 is a navigational compass, similar to Brunton TruArc 15, the Geo Lite also has a protractor printed onto the baseplate which is specifically used for mapping geologic data onto topo maps.

Finally, the Suunto MC-2 lacks a bubble level, which both Brunton models come with as standard, meaning no geologic measurements can be taken with the Suunto model.

 

Brunton TruArc 15 Compass

TruArc 15 1


This mirrored baseplate compass offers professional features like an internal vial inclinometer and lid inclinometer that is ideal for advanced navigation, search & rescue, or scientific field work. It's a navigational compass, pretty much like the Suunto MC-2.

 

 

Specifications:

  • Dimensions: 4” x 2.5” x 0.6” | 10.16 x 6.3 x 1.5cm
  • Weight: 3.2 oz | 91 g
  • Resolution: 1˚ Resolution

Features:

  • TruArc™ Global Needle tilts up to 20˚ for balanced use world wide
  • Tool-free declination adjustment is simple and fast to orient magnetic north to true north
  • Meridian lines on vial assist during pre-trip planning when aligning with map grid lines
  • Inch/millimeter scales for accurate and effective map work
  • Brunton EverNorth Magnet resists demagnetization over time
  • Magnified readout provides highest degree of accuracy without compromising readability
  • Dual azimuth ring includes reverse azimuth 
  • Sighting mirror and sighting line integrated into the cover. Align for the most accurate bearings, whether taking or following a bearing
  • Clinometer with 2˚ resolution for measuring slope angle or gauging heights of passes, peaks or trees 
  • Engineer’s ruler
  • Bubble level for absolute precision readings; keeping the compass level (not the needle level)  is a critical aspect for taking an accurate bearings
  • Map magnifier helps with the smaller details on any map 
    High visibility cling for enhanced performance in low light; can be removed to facilitate map use
  • 1˚ resolution azimuth ring provides precise readings
