Equinox noise cancel in the air at waist height or on the ground question

[pulltabfelix]

I have read where some hunters noise cancel with the coil on the ground to get a better reading from the ground. Any thoughts on this technique? Anyone using this method for noise canceling.

The theory being that better you ground balance and noise cancel along with lowering the sensitivity the quieter your machine will be. This allows you to hear more of the deeper faint signals even by lowering the sensitivity because you have achieved a quieter machine. Of course this will vary according to ground conditions.

Fair question, I've heard both ways, in the air, on the ground. ??

I noise cancel mine about 10 inches off the ground.

 

[sprailroad]

Pretty much what I've been doing Hawks.

 

[Hawks88]

This is the way I have done it since day one. I’ve never had a problem.

Same. I noise cancel mine in the air and not on the ground; but, curious as to what others are doing and what input vferrari may have on this.

I use an E-TRAC and I noise cancel with the coil on the ground. I figure any above ground radiated EMI will still be present with the coil at ground level.

 

[cudamark]

Noise cancel is for EMI and other electronic signals that might interfere with your detector. It shouldn't make much difference if it's on the ground or in the air, but, I do it above the ground figuring that's where the interference would be coming from. I ground balance with the coil on the ground, or pumping as the case may be.

I don't know if it makes any difference, but after testing both methods mentioned already, I decided to put the coil just above the surface to cancel. That's where my coil will ideally swing during hunting. Seems to me that it might molest the integrity of the cancel or GB, if the coil actually touched grass/soil.

Noise Canceling at waist high is the proper method. Noise canceling has NOTHING to do with Ground Balancing.

I hold mine like Jesse Ventura holding a mini-gun in Predator. That is proper way to noise cancel the Equinox.

I tie a piece of rope to it and swing it over my head during noise cancel. Let’s everyone know I have arrived and am ready to kick butt.

Now that’s funny!

I tried that, and works really well. I tie the rope around the arm cuff, and after noise cancel is done, I clip the other end of the rope to my belt, this way after I finish digging a target and continue walking on I don't forget my detector.

Why is this a question, BTW?

I waited for someone to point this out, but nada.

P.39 of the manual: Noise Cancel Step 1. Hold the coil stationary and away from the ground.

Hmm. Guess I shouldn't be swinging it over my head.

As Terry said, sounds like some folks are mixing up GB and noise cancel.

Great to read the forums and all the theories, but a really great place to start is reading the manual that comes with the machine and you can start the discussion and debate from there. Usually, I trust the manufacturer to not be giving me bum dope.

As far as noise cancel is concerned, it really doesn't make a lot of difference if your site is not that noisy to begin with and noise cancel does nothing on intermittent and transient noise. Ever tried to do a noise cancel twice in a row? Ever notice how you never get the same number twice in a row? Probably because there are a number of clear channels Equinox can choose from in that case. What I am trying to say is don't overthink it. Run a noise cancel and hope for the best. Trying to over tweak it by precise positioning of your coil in the air doesn't make a hill of beans difference. Doing a noise cancel near the ground may cause the noise cancel to be less effective due to a lot of electromagnetic theory mumbo jumbo I will not bore you with so just trust ML when they say noise cancel with your coil away from the ground. That's about as precise as it has to be. If you have an 800 and auto noise cancel still gives you EMI, manually select the quietest channel. Noise cancel is unlikely to cancel out all the noise in bad EMI conditions and unlikely to matter in low EMI conditions so don't expect it to work miracles or make much of a difference most of the time.

Cudamark, Terry and Vferrari are correct, noise canceling is to cancel out as much EMI in the air as possible, ground balance is canceling out the noise in the ground. I always cancel with my coil pointed forward about waist level myself.

 

[McKinney_5900]

Noise Canceling at waist high is the proper method. Noise canceling has NOTHING to do with Ground Balancing.

I hardly ever GB. Sorry if I mislead anyone by including GB. When I do GB, I pump the coil nearly to the ground, about the same level I noise cancel. In the end, I really doubt it makes much difference either way.

 

[cudamark]

Same here. I rarely have to do a ground balance or noise cancel. Just doesn't seem to be an issue where I hunt most of the time. I mainly have to noise cancel if I'm hunting close to another detector, or close to a WiFi source (which never seems to help much anyway).

was that mud replying? certainly not vferrari.
