Ground balance question

[foreign object]

Got my 705 last Friday and haven't got to use it much but have a question.

When in Tracking the manual says that the ground balance reading/numbers will show. Well I do not get any input at all as to the GB number. I can press accept/reject and get a reading of 20 or I can push the GB icon and get higher numbers.
What am I missing or doing wrong.?

The 20 number sounds really low.When I run my CTX in the same spot in auto+3 it suggest sen.22 and runs at 26 to 27. I was always under the impression that those numbers indicated mild soil but I may be wrong.

Any help or advice is appericated.

By the way I think I am going to have fun running the 705. Simple but effective which can be a good break at times.

thanks

I don't know about the CTX, but with the 705 the higher the number the less ground phase compensation is required, meaning the milder the ground. The lower the numbers the hotter the conditions.
Pressing the GB icon allows you to monitor the ground phase when tracking is on, or to set it manually if tracking is off.

I've only had my 705 for a few weeks but love it. I am using it more than my eTrac right now. You are going to love that machine!

Thanks Longhair.
I was just concerned that there might be a problem as the manual states that it will show the GB number when in tracking and that for the first 3 seconds that it wil give real fast readings and then settle down. Guess that the manual is misleading to me.

Only worked it in my test bed and was proud of the fact that it could hit my 8 in. dime with about 3 in. of grass on top of the 8 in. with the stock coil.

thanks again

I'm not sure I completely understand what you've encountered. But let me share a couple thoughts.......To access the GB setting, you must press the GB pad. Ground phase numbers only appear when you are in that Ground Balance setting mode. Once you press the GB pad, you will see the ground phase number that the 705 is currently set at. You can adjust that number manually, automatically or with tracking. You adjust it manually by pressing the + or - pads. You set it automatically by pressing the accept/reject pad. When you are in the GB setting mode, the numbers on the display are ground phase numbers. After making adjustments to your ground phase, or just checking to see what the ground phase is, you must press either the GB pad or Detect pad to resume the detecting mode. When you go back to the detect mode, those numbers on the display will represent the TID.
Tracking is like having Auto GB on the fly. It is implemented by pressing the Tracking pad while you are in the GB setting program or while you are in the Detect Mode. When you activate Tracking while in the Detect mode, it will adjust itself very quickly for the first few sweeps, then continually make adjustments as needed. You won't be able to monitor changes in the ground phase numbers when you activate it in the detect mode. If you are hunting and want to deactivate Tracking, press the Tracking pad. And if you manually change the ground phase while in Tracking mode, it will deactivate Tracking.


If you've not taken the opportunity to read my eBook, "Understanding your X-TERRA", I'd invite you to do so. I've tried to include a thorough description of the various ground balance options. The eBook is available FREE on Minelab's website. http://www.minelab.com/treasure-talk/understanding-your-x-terra-ebook The section on GB starts at page 16.


As to your CTX and the X-TERRA.....it is tough to compare their GB capabilities, due to their different technologies. Briefly......in the "normal" hunt mode, the CTX combines the Auto Sensitivity and ground compensation to neutralize the effects of mineralization. There are no adjustments (or requirement) to ground balance, due to the FBS2 technology. The CTX choses which of the 28 operating frequencies are least affected by the mineralization, and implements those frequencies as you hunt. The single frequency X-TERRA allows you to set the ground phase (manually, automatically or via Tracking) to compensate for the effects of mineralization at that frequency. It then allows you to set the Sensitivity level separately. HH Randy

Thanks for the reply Digger.

Actually I did down load your EBook a couple months ago and between the book , Longhairs comments and the many positive reviews is what led me to buying the 705. Excellent book and you should be commended for your work putting it together and offering it free to all. Thanks man.


Now let me see if I understand things correctly on using GB Tracking.
If I press the GB pad and then the Tracking pad I will get the GB numbers and then by pressing the detect or GB pad again puts me into detect mode. If I want to check the GB numbers later I can press the GB pad again and the GB numbers/reading will show.
I did do a auto GB and if I go the tracking correct I was surprised with the low numbers. Auto came out 35 and tracking 27-28. I guess my yard is hotter than I thought. I can run max sen. and the machine has perfect manners.
I am going to like this machine and will be perfect for its intended use.

Have not been able to spend much time with the machine yet been busy putting in this winters stock of fire wood. I do appreciate your time and I hope the best to you and yours.

I had just misunderstood the manual and was under the impression that I would get a ground phase reading while I was in the detect screen/mode. I am on go now and thanks for yours and Diggers help.
Best to you and yours.

If you press the GB pad, you will see the current ground phase measurement. You don't need to press the Tracking pad to see the ground phase. The only reason you might want to check the ground phase with tracking turned on would be to see how quickly the mineralization levels change as you sweep the coil over the ground. But you are correct in that to get back to the "hunt mode", you can press either the GB pad or Detect pad. And if you want to check ground phase numbers at any time during a hunt, all you have to do is press the GB pad. If you had either manually or automatically set the GB, those ground phase numbers will show. If you are in Tracking, it will display the current ground phase, based on what the Tracking software had determined to be optimum for the soil that is directly below the coil at that given time.

Since the GB subject is being discussed, I have been using my 705 with the 5x10 18khz coil in a local park. The park dates back to the 1920's and before then was open farm land and forest. I have been using auto GB and have been seing a GB of 0 to 1. this seems very low to me but checking it with manual GB the munbers are the same. Has anyone experienced these low numbers? Sensitivity is at 23-25 and unit is in all metal. I run ground phase and usually channels up at 1.

Sounds to me like you have inadvertently put it in "Beach" mode. Is the beach umbrella icon lit up on the screen? If so, press the GB button to enter the GB menu, and then press and hold the GB button again for three seconds to switch it off.

 

[hunt2getm]

Yes, you are absolutely right! I was in the beach mode..somehow my eyes think the little umbrella looks like a coin.......did a factory reset and now all is good. Thanks so much!!!!!!!!!!!!!!!!

I'm glad that it was such an easy fix.
