The EFNMR2015 system uses earth field resonate frequencies. The unit is set to the magnetic field of the earth in the area you are hunting. This is done by the NT magnetic field value and once set, the instrument calibrates all element frequencies for that area.
This is a professional unit and you should have a good background in using Long Range Locating equipment. I do not use sine or square wave signals. I designed my own signal and works very well with body response.
I was also the first to use combined frequencies for mixed elements. I can calculate a frequency from a chemical formula.
You are purchasing the very best long range equipment packed with features not seen in high dollar systems.
Note: Rod does not come with unit...
My rods are machined by me. The handle is made of 1/4" brass rod with an antenna element up to 24" in length. You can adjust the length for your liking.
The rod can fold and fit in your pocket. The 1/4" handle works great on a windy day giving you more control of your response.
Easy to use and store. Get one while supplies last.
