Ground Balance On The Safari........

[morelic55]

The manual states that it uses digital filtering, does that mean that it has a "Set" ground balance or "Auto Tracking" like the Xterra 70? Just curious...........MO

Your Noise cancel feature sets you ground balance and selects the best frequency for the conditions of the ground you are hunting. It is a simple one button adjustment Place the coil over a part of the ground that is not showing any metal, hit the Noise Cancel button and you are ready to go. You can do this as often as needed to reset in about 20 seconds. Onus

The Safari has an automatic ground balance. Noise cancel has nothing to do with ground balance, but chooses the best frequency in the in the presents of other frequency noise in the area including other metal detectors being used near you. When ground balancing , hold the out at "Waste Height" and than noise cancel. Do not hold it over the ground.

It has a factory set ground balance and that the machine does not auto GB to the soil?

The Safari has Automatic Ground balance.

From the manual:
Ground Compensation
Safari uses a sophisticated approach for
the elimination of ground mineralisation
effects. It uses advanced digital filtering to
eliminate the influence of ground signals. [size=large]This
is achieved automatically, allowing you to
concentrate on detecting targets.[/size]

Thanks, I read that too, but I have a hard time believing that it is "Automatic" and not hard set like some other detectors. I guess I'll have to try the ol' put it in all metal mode and drop the loop to the ground. If it stays stable and does not go up or down, then I guess it is auto!!!!!!

It was touted as one frequency see's the ground and the other frequencies see the targets..I have never read Minelab changed that approach..just different wording indicating the same thing. So if you have a 17, or 28 frequency it seems that one see's the ground and the others see the varied targets.. My assumption has always been Multi frequency changes to the correct seeing frequency as the soil changes along your detecting route. So in a sense that would be automatic...

Automatic ground balance VLF.
Metal detectors with automatic ground balance measure the average amount of X contamination in the audio signal. Slowly,
the amount of X signal subtracted from the R signal is varied so that the average amount of contamination in the audio signal is
minimized on average. The rate of how quickly this adjustment is made must not be too fast as this will also cancel out the weak
R signals from metal targets because the metal detector will

Ok John, let me get this straight, "Noise cancel has nothing to do with ground balance", right? But then you say hold the coil at waste (waist) level and hit noise cancel to ground balance and don't touch the ground. I have to ask you, if it is auto ground balance, how is that procedure going to ground balance? I once long ago had a BH detector that used a similar procedure to ground balance, but I don't recall anything like that to ground balance a Safari. Given on further rereading a Safari is auto ground balanced, so I can't see how that is going to ground balance it. I misspoke in my first post confusing noise cancel with ground balance. That was because noise cancelling has much the same effect as ground balancing, ie, knocking out a lot of the clutter. Onus

If you notice my next remark, I wrote what I ment to say. Correction I ment to say " When Noise Cancelling".. I just typed in Ground Balance by mistake. It is Auto Ground balance. My Mistake (TYPO).

When balancing is done (White's XLT) waist height is one of the procedures. I haven't read a manual requiring a waist height holding of the coil for the Safari. For noise cancelling the manual; says to hold the coil approx. 12 inches off the ground. Some leave it on the ground. It may be a personal preference as the machine is just doing a noise cancel. Could the ground itself be putting out noise frequencies ? Or is it because when we are actually detecting, the coil is on the ground ? So many points of view how many actual truths ? Ron

 

[hershey1]

I don't know about waist high but get yourself a good shovel ? digger because when you start swinging that coil around you are going to need them. My 2 cents worth. HH

I just finished Andy Sabisch's book and understand now how it works. Noise cancel with the COIL ON THE GROUND and the Safari is totaly automatic as far as ground balance. He also say's to noise cancel every 30 min or so when hunting because of the ground minerals changing........If ya don't have his book, GET IT!!! It's worth the $15 for the information. Hummmmmmmm I also did not know that Mike Scott had a hand in the Quattro also!!!!!! MO
