Can someone explain what the operating frequency is about? Some brands are low some as high as 19 KHZ. What is the difference ? Higher better? Help please And Happy New Year

Charlie meant well but his math was bassackwards. Higher frequency is (all other things being equal, which they never are) better on the smaller and lower conductivity stuff.
I think I wrote my got all up screwed. Happily I'm not an engineer or the nurse dispensing your medication.
I was looking through some old W&E Treasure magazines and there was a Garretts ad discussing the merits of a single frequency over a multi-frequency detector. A few years later other brands were claiming just the opposite.
Does a detector do better sending and receiving a single frequency or is a broadcast more effective? Or does it make no real difference at all as they're just detecting the effects of conductive items within the coil's field?
I know ain't nuttin ever easy but it would seem the larger & higher conductive items are "low hanging fruit" and a detector will react to them regardless so a higher frequency would be desirable for the smaller items. There must be a trade-off (or ten) in penetration or signal corruption of the higher frequencies or some such?
This thread contains so much great information, the link to the gold prospecting pdf is of great value to me. It is wonderful that those with so much knowledge are here on treasurenet. Thanks.
Yes the .pdf is awesome. I printed it out and have read it a few times. I almost feel guilty it was free!
Ok not an expert, but the higher frequency coils are putting more khz per sweep, lets say 50 khz as opposed to an F5 at 7 khz (or so) hence the ability to find smaller objects. Since gold is a lower conductor, it responds better to a high frequency, that is 'seeing' that conductivity better. Silver being a high conductor, doesnt needed as many "waves" (think 5 or less khz) per sweep; as it conducts so well, it is easier to 'see' with a low khz. This may not be exactly explained properly, but I think it's close, lol.
Sorry ,but I have too say Gold is a high conductor , but usually found in a smaller quanity .
Wow, it is common knowledge that gold (like lead) is a low conductor & higher frequency machines are better suited for the task of gold nugget hunting. A simple google search will prove it.Sorry ,but I have too say Gold is a high conductor , but usually found in a smaller quanity .

Sorry , I was thinking tone wise , not so much conductor wise .
I guess that all depends on the machine you are running and having the ability to set your tones up .
