Pushing A Detector To It's Limits Of Being A Little Erratic Pros & Cons

[Bill G]

Just a thought, some pros & cons on maxing out a detector to the point of being a little erratic.

Sometimes when we set up a detector for max depth buy cranking the sensitivity to the edge of being erratic or slightly erratic behavior for the sake of depth it can just plain wear you out listing to the noise. This can cause us to miss targets because we do not hear them over the chatter so turning the sensitivity down a little to stabilize things lets us hear the targets better. It also allows for less fatigue during a long days hunt at minimum or very little depth loss over all considering the detector is now running smooth and stable allowing us to pay attention to what were hearing in the headphones instead of trying to filter good target signals through erratic background noise in the headphones. Pushing a detector to its limits is not always the best way to go nor does it always get us more depth.

In all reality the ground conditions along with the ground balance of the detector dictates the total usable sensitivity gain we can get over all out of the detector.**** Depth is really a side affect of these variables anyway and is subject to change based on any changes in the ground conditions, ground balance of the detector or sensitivity settings of the detector.

The chatter can become normal as just a running noise with the volume set right, or low enough. But if you run it to sensitive it can false signal, then that's when you have to turn it down.

Tips and pointers on the subject would suggest that a new user run the detectors settings low enough below the chatter starting out, then after they learn the detector and what its saying then you can turn it up for more depth and not let the chatter be nothing more than a point of MAX sensitivity.

Mark,

I agree here as well (good point) and tend to run my detectors at the point you mentioned in your post max sensitivity with with some noise showing the point of max sensitivity. The point I was touching on is there is sometimes a fine line between that point and over driving the detectors gain causing the issues discussed in the original post. Guys think there getting max depth turning the detector past the point where talking about to only miss out because they do not hear the target due to excessive gain or sensitivity reaping havoc on the detector.

I also agree beginners should work there way to the point you are talking about by running the detector with less sensitivity while learning the detector being used.

Well said Bill G.

How does the threshold adjustment come into play on this issue, on F75LTD?

You set your threshold to a point that you can just hear it or at the level you prefer, then run our gain or sensitivity up to the point it starts to chatter then back it down a little at a time until stable or if you prefer just enough to still hear some slight or faint chatter, this is the point of max sensitivity or the max gain that the detector will except.

Threshold at one time just meant setting it like you stated, "a barely heard running audio tone" but on some of the silent search detectors the "Threshold" is different like the Fisher Coinstrike.
Isn't the F75 a silent search detector?

On the F75Ltd the threshold is only on the all metal side and not on the disc side. But the threshold noise is not the same as the same noise as pushing the sensitivity high. The threshold can and should be ran right at the edge of where you can hear it. Now the sensitivity noise you get with to high of a setting is not a background noise it it is right there at or close to the level of your target response. The best description I ever hear was from somebody on this forum and I hope he doesn't mind if I repeat it here. He said running the sensitivity to high is like driving your car in the fog with your high beam lights on, you are blinded. So when you feel blinded or blasted with chatter turn it down.

This is something I had to learn. I use a Conquistador Umax that has no GB controls and I have to watch working in more mineralized conditions. Instead of trying to get as deep as possible, I turned it down to listen better. Though I can't tune out the chatter, I can lessen it and let the detector speak a little clearer to me. And it does pay off at times.

a little erratic--i will run my coil hotter when targets are getting few and far between...up until that point i will run a smoother setting.........................................pros of a hotter setting----you can find targets other people missed...... cons----if you run too hot you will be wasting alot of time chasing too many junk signals........ i find it best to run just a hair hotter than the last guys settings....that way there is still some contrast between better sounding targets and trash,nails,bottle caps,etc..... however if im in a spot where ive already dug several good targets then i dont mind dugging some junk in hopes of scoring another good target that might have otherwise been missed......
