Brunton Miner's D-Light Illuminated Transit Compass

Brunton Miner’s D-Light Transit

The illuminated geological transit built for mines, caves, and low-light fieldwork.

Introducing the Brunton Miner’s D-Light – the world’s lightest illuminated transit, purpose-built for geologists, speleologists, and mining professionals who work where sunlight doesn’t reach. Featuring battery-powered electroluminescent lighting, this field instrument makes it possible to take accurate readings in the darkest environments—without relying on torches or headlamps.

Made in the USA and available now through Prospectors Supplies, the Miner’s D-Light is a reliable, low-light solution for geological mapping and underground surveying across the country.

Why the Miner’s D-Light Is Essential for Underground Work:

• 60-Second Electroluminescent Illumination
  At the press of a button, panels light up the azimuth ring, baseplate and bubble levels—ideal for use in mines, caves or twilight conditions.

• Precision Without the Glowsticks
  Provides accurate azimuth and vertical angle readings using a traditional transit mechanism, even in total darkness.

• Lighter Than Ever
  Weighs less than the Brunton ComPro Transit—making it the lightest Brunton transit available.

• Safe, Non-Radioactive Illumination
  Runs on a standard 3V battery that’s easy to source and completely non-magnetic, with no radioactive materials.

• Magnetic Needle with Global Balance Options
  Order the needle balanced to your region (Australia-friendly options available) for reliable results wherever you're surveying.

• Durable Composite Body + Water/Dust Resistant Seals
  Built with Brunton’s signature toughness, O-ring sealed internals, and a reinforced composite housing for long-term field use.

• Comes with a Quality Leather Field Case
  Designed to protect your transit on even the roughest expeditions.

• Compatible with Brunton Jacob’s Staff and Ball & Socket Mount
  Easily integrates into your existing field setup.
