White's Multi Frequency VLF Detectors And Search Coils

[nevadad00d]

Does anyone know if the White's multi frequency vlf detectors such as the VX3 and the V3i search coils have just one coil for the transmit and one coil for the receive or are there separate sets of transmit and receive coils in the coil housing for each frequency? thanks

Three separate sets - that would be a heavy coil! No, just one transmit coil and one receiver coil. Nothing that special really, the MXT uses the same coils.

Ah, thanks Steve, that was my hunch, that's why the 3 frequencies are all odd multiples of the lowest frequency. (3 and 9)

2.5, 7.5 and 22.5 KHz. With transmit and receive frequency offsets running as much as 600 Hz above or below the default frequency in most models, it tells me how much I can be off from a given coil running an odd multiple higher than the frequency the coil is designed for. I'm looking at possible 10" elliptical DD coils that may work for an older VLF machine.
