Dielectric: A value assigned to materials and is used to calculate the velocity of RADAR in that material. RADAR will

travel at different speeds depending upon the material and/or soil condition. RADAR travels fastest in air (dielectric = 1)

and slowest in water (dielectric = 81). Everything else falls somewhere in between. It is important to know the dielectric

value of a material so that the depth of a target can be calculated. Since determining dielectric is a best guess estimate, the

depth of a target will never be an exact measurement. As a safety feature, you will always give about a 1 foot (or about

1/3 meter) margin of error when estimating the depth of a target.
