DME

The DME is a classic ultrasound measuring system and perfect to use in sample plots.

THE DME

ULTRASOUND DISTANCE MEASURER

The DME instrument system from Haglöf Sweden offers speedy and reliable results for distance measuring in the forest. The DME system works with ultrasound technique, making it especially useful in dense terrain and where underbrush is thick. The built-in BAF functions are useful for point/plot sampling work. Basal Area (BAF)

The complete DME system includes the small and rugged DME measuring instrument, a transponder T4 and plot staff/monopod with adapter. The monopod with transponder is placed in the plot center, allowing the user to measure and determine the plot radius.

DENSE VEGETATION...

The complete DME system includes the small and rugged DME measuring instrument, a transponder T3 and plot staff/monopod with adapter. The monopod with transponder is placed in the plot center, allowing the user to measure and determine the plot radius.

MEASURE IN A FULL, 360° CIRCLE

The exact plot radius can be measured from any direction to the plot center when the T3 transponder is mounted on the monopod and the custom 360° adapter.

...IS NO PROBLEM FOR THE DME

The DME works with ultrasound technique Haglöf Sweden’s ultrasound instruments are tested and proven reliable in all types of terrain and conditions.

BAF FUNCTIONS BUILT-IN

With the Basal Area Factor (BAF) function you will know the minimum diameter for trees to be counted and included in the plot.

DME – DME

The DME can also work in pair, with two DME measuring instruments measuring the distance in between. This method is useful to maintain equal width for example in road construction work and when clearing along power lines.

T4 Transponder

T4 is the new and improved Transponder that replaces the T3 and all previous transponders.

T4 is equipped with six built-in LEDs that provide essential information:

  • Instantly know if T4 is active and responsive with your measuring instrument.
  • Identify any disruptive noises for accurate measurements.
  • Experience the convenience of T4's new housing features:
  • Extended battery space for all brands of 1.5V batteries (AA).
  • Updated electronics for a longer product lifespan.

T4 is fully compatible with older measuring instruments, making it a seamless upgrade for all users.
