Hello detectorists,
I am thinking about the diameter of the bucking/receive coil compared to the diameter of the transmit coil.
Most of the detectors use for the bucking/rx-coil diameter the half of the diameter of the tx-coil.
What is the result, when using for bucking/rx-coil
2/3 diameter of the tx-coil
1/2 diameter of the tx-coil (most detectors use)
1/3 diameter of the tx-coil?
Which of them would bring good results for tiny objects (e.g. small gold nuggets)?
Has anyone experience about this topic?
To small rx-coil would reduce the detecting area and to much rx-coil would increase the detecting area but would reduce the sensitivity for small objects. On which diameter relation would be a good compromise?
