Minelab Sled coil interference.

A fellow prospector who is going to the West, asked me if he would be able to tow a sled coil behind an electric trike/bike, or would it pick up interference from the electric motor? I haven't got a clue, so I said I'd ask on the forum. Does any one know the answer?

I went from a 3 AAA battery led lensor light to 4 AA battery led lensor light and it sent the 5000 crazy. Not answering your question directly, however it show how sensitive they are.

I think the answer is probably yes, as electrical interference is the reason that diesel engine quad bikes are used for the task.

The below info is provided curtesy to a email reply to a similar question I once raise with JP back in 2012

The Answear is:
The GP series of detectors are the best for Quad bike drag coil operations, the GPX range are very twitchy with interference and hard to get adjusted correctly from a noise point of view

Interference comes from the battery charging arrangements on the quads which is either via alternator of generator, either way it can be bad hence the need to us an AI coil. A diesel powered quad works best for this very reason and put a switch inline on the charging circuit, with petrol powered bikes they have a coil and spark plug arrangement that can be very noisy. Thermo fans can also be a source of noise.

Most operators I know use a 3000 or 3500 with threshold backed off to near nil with a B&Z booster amplifying the sound through Koss headphones, placing small nuggets down on the ground they then drive over them adjusting the threshold till the nuggets can be clearly heard over background noise, using this method 2 and 3 gram nuggets can be found at 8Klm and hour speeds on or near the surface.
