Tired Of Manual Ground Balancing

Maxene

New member
I live in Upstate New York, Henderson Lake, settled 1741,along the Hudson River. At present, I own a CZ6A and the Tejon. I am a rural route mail carrier and obtaining permission to detect is never a real problem. Some parts of this area the ground can get pretty nasty. Some of this ground the CZ will lose depth, so I have to rely on the Tejon to make up for the loss of depth and I am more than happy with these two detectors. There are times that I would like to enjoy using a detector that does the ground balancing itself...I have read a lot about the Fisher F Series and the Racer and could care less about any type of screen with numbers...I always set my discrimination at the lowest setting and go from there...If I am wanting depth, I will use the Tejon...Anyone care to help out.
 
Hello Maxene,

I bet you make some fantastic finds in that area, lots of history!

Ground balance is one of the most important features on a detector in my opinion. The more options available on a detector the better.

You mention the Fisher F series. They currently have a very good deal going on them! For about $500 you can get an F75 gold. They were also including a 15" coil as a bonus. Not sure how long the bonus coil will be offered. The F75 has what they call "Fastgrab". You do the initial GB which is very easy, and the machine continuously monitors the changing ground conditions, at any time you can use the trigger to instantly reset (Fastgrab) to the current ground phase. Very simple and quick. It also has a manual GB in All Metal mode if you choose.

One of the best choices in ground balancing IMO, is the Whites MXT All Pro. It has Auto Track to automatically monitor and set the GB, and you can lock that setting with the trigger when a target is detected, so the target isn't tracked out as bad ground. It also has the "Ground Grab" system to instantly update the the GB to current ground phase with the trigger, if you don't want to use the autotrack. Ground Grab can be utilized even when autotrack is used though. It has manual GB also. It doesn't get any better than that for GB options!

Not really.....set ground balance can cause loss of depth and sensitivity.....

Not sure what you mean by that Dan? The fixed, or preset systems? Personally, I wouldn't own a preset GB model. Adjustable models can be had at about the same cost as preset, and be more useful in changing ground.

Ground balance is simply balancing the detector to the ground mineralization phase, so it doesn't read that mineralization as a target, or causes it to act erratically, which can cause the "loss of depth and sensitivity" you mention.

Detectors with fixed or factory preset GB are limited to efficient operation, only in ground conditions within the scope of the ground phase employed in the preset. I believe that may be what you referred to in your post. If so, I totally agree! I have detected with folks with preset, (non-adjustable) GB, and seen their limitations. In most cases, they don't even realize they are losing "depth and sensitivity" unless their machine acts erratically. I have seen a few post in these Forums in which the person has quantified that loss of depth. In one case the individual was getting 8" of depth with his fixed GB detector. He moved a distance away and was only getting 4" in bad ground. A 50% reduction! In some cases it makes the detector totally unusable.

Auto tracking systems automatically monitor and set the GB to changing ground conditions, but, they have limitations also! When auto tracking is employed, when a possible target is found, and you move the coil back and forth over the target, the auto track system can actually view the target as bad ground and track it out. That is why the track lock I mentioned on the MXT is invaluable.

Manual systems work fine, but, adjusting manually in bad ground can be tedious.

The "grab" type systems are probably the easiest. One thing I like about many fisher products, is that they give ground phase information, so you can know if the ground conditions are changing. None better than the Fisher F5, IMO, it shows the current numerical ground phase, and the current numerical ground balance setting of the machine. Keep those numbers matched, and the detector is balanced to the ground conditions.

You mentioned the Racer. Not sure about the Racer, but my Racer 2 has manual ground balance. It is very easy to ground balance though. Very simple but capable machine.
