hi its been a long time since I last detected anyhow I have a question when you suspect that theres a target do you ground balance on top of the target or just to the side also can anyone please let me know the process of ground balancing too also is it better to detect in fixed or tracking please let me know thanks tim

Hi Tim
Never ground balance on a target, ground balance off it.I run in fixed and ground balance often.When you get and inground response scrape the top with your boot , this should improve the signal. If the signal has increased dont dig a hole with sharp edges.Dig a hole like a saucer to start rather than a hole with sharp edges Ground balancing is important to get your machine running as smoothly as possible. From memory you are running a 4500.Cancel out emi by placing your machine on the ground with coil flat and press auto tune, dont touch it and let it run thru its cycle.
Now for ground balancing make sure its in tracking and pump it from ground level 5 inches off the ground 4 to 6 times.On the last down stroke when you reach the bottom turn it to fixed.
Its still a bit noisey in the triangle due to moisture. Run in tracking when you cant keep machine stable
Cheers dig

Some sound advice given to you by Dig24crt Tim. When running in fixed tracking (the preferred choice for many an SD 2200 to GPX 5000 user) & one suspects a signal response beneath their coil, it is always wise to do a quick ground balance, a foot or so away from the suspected target, by switching back to tracking during the ground balance procedure & the moment the ground balance is found to be stable, flick it back into fixed tracking.
Ground balancing the 4500 consists of bobbing or pumping the coil up & down half a dozen times or so, to within an inch or two off the ground, till the coil becomes stable & or is seen to run smooth or silent over the ground one intends swinging over.
If the ground one intends on covering is found to be constantly changing & highly mineralized, then one should ground balance often when in fixed, in order to make sure your coil is working to peak depth efficiency, eliminating the possibility of false ground signals coming through.
As Dig24 states, run in tracking where the above mentioned ground conditions are encountered &/or over ground that is saturated with water/moisture.
Keep in mind, when one's preference is to run in tracking mode, the old adage of running "low & slow" applies, so that one allows the tracking system to not only cancel out noise from ground minerals, but ground balance properly, to its full potential/depth. A fast swing or walk speed, restricts proper ground tracking when in "tracking" mode, than in "fixed".
After pinpointing a suspected "positive" target response,  dig a hole as evenly flat as possible as the ground allows, to a size a third larger than the size of coil that one is using. The reasoning behind this, is to always allow the coil a flat ground approach towards the target, for maximum ground signal response, as well as accurate pin pointing.

Next time your in Maryborough go to Coiltek and get directions to the Test Patch.Its a good way of practicing to get your ear accustomed to inground targets . Also remember to anytime you flick a switch, you need to regroundbalance
