Help With Equinox Ground Noise

[67GTA]

It is strange. My Vanquish doesn't do this on the same ground. Equinox must be more sensitive to the ground minerals. Guess I can look for the iron patches in single freq and then switch to multi.

Usually, ground balance takes care of this.  I see that you are ground balancing, so obviously that isn't the issue.  If increasing recovery speed is not helping, one thing you can try is biasing your ground balance setting manually in an attempt make the ground noise go away.  In other words, do the auto ground balance and then push past the balance setting in either direction to see if it clears up constant ground noise, if you want to search in multi.  Just reaching here but it is worth a shot and I suspect one of the reason they give you full manual control of your ground adjustment.  Worth a shot.

If you are getting ground noise that mimics targets do these ghost targets give you discernible tones and target IDs? 

What mode are you trying to run in multi, what is your sensitivity level and have you tried Beach 1 or 2? What is your iron bias setting?

Is your phone on airplane mode or off? Are there electric cattle fences in the area or cell/radio towers or even a small airport?

I get the desire to run wide open with nothing discriminated. The Equinox in multi will not lose depth if you can discriminate out the iron range number or numbers that are causing the ghost targets.

Sometimes when I am gold prospecting I have to at least discriminate out -9 in order to not hear the ground no matter how well I ground balance. Otherwise, I can't tell an actual target from ground noise in certain types of high mineralization if it is coming from iron particles or other hot rocks. 

If you are dealing with coke, coal cinders, previously burned ground, heavily fertilized/manured ground or salinity the target ID numbers should tell you especially if they are occurring between -2 to +2.

The Vanquish is always running with a form of saltwater beach assist engaged. You can't turn it off. This might be the reason that the Vanquish is quieter than the Equinox. Like you said however, the Equinox is a much higher gain detector than the Vanquish.

They aren't repeatable signals, but usually show up around -9 to -3. Most square nails are around -3 to -6. Guess I could notch out to -3 and still hear the iron. Just got about 5 inches of snow, so it will be a few days before I can try beach mode. I've tried all the park and field modes, and run sensitivity as high as possible. Turning down the sensitivity doesn't help much either. Never thought to try beach mode. That might make a difference if it is mineral/salt related. Hunt a lot of rural areas with crop fields and pastures. Could just be a lot of fertilizer in the ground. I run into a little red clay every now and then, but it is usually pretty quiet.

Interesting thought.  I look forward to other repies and your tests when the weather clears.

Might get to play in the mud next week. Supposed to be in the 50's Sunday!

67GTA, I am having the same challenges you are facing...and I thought it was just me! At first, I thought the shafts weren't tightened enough, but when that didn't fix it, I decide to try other things, I ground balanced then tried to manually try to eliminate some of the falsing, but to no avail. I currently run on park 1, with sensitivity at 22. I do the noise cancelling and ground balancing. I have tried switching to different modes, but still nothing. I am only one month into my Equinox and I'd sure like to find an answer!

This may seem silly but have you tried cleaning out the crud from the coil cover?

 

Yeah, don't ask me how I know that....?

As a User Program I still use the Beach1 or Beach 2 program .. .. with a slightly higher iron bias setting ... it's mainly for checking suspicious signals, / a good signal usually has the same ID in both programs..but also signal modulation ../ but also so quickly I will find out which program can work more stable on a given field the best ..
