X-TERRA 50 SET-UP

[cintitomcat]

What is the best way to set-up x-terra 50 for max depth, ground balance, etc? Using either the stock coil or the 10.5 mf coil. Seems when air testing these 2 coils the stock coil is 2'' or more difference. Thanks Tom

It doesnt' surprise me that the 9-inch concentric coil gets better "air test" results than the DD. And if your ground mineralization is low enough that a concentric coil will operate well, then I'd expect similar resuts in the ground. My rule of thumb for determining whether or not I would benefit from a DD coil is simply based on the Ground Balance number that you get when properly ground balancing your detector. On your X-50, if I could obtain a proper ground balance with a ground phase reading of 6 or a larger number, I would put on the concentric. If the ground phase reading was a 5 or lower, I'd opt for the DD coil.

I go into quite a bit of detail in the eBook on how to properly set up the X-TERRA. But briefly, here is how I'd set up the X-50....... Turn it on and set to All Metal mode. Turn the Volume up to Max. Set the Threshold so it is just barely audible. Turn the Sensitivity to 20. Hold the coil at waist height, parallel to the ground and find a Noise Cancel Channel that is quiet. Scan the ground to make sure you aren't going to do your Ground Balance over a piece of metal. Once you find the spot to ground balance, turn the Sensitivity back down to 10. Hold the coil about 6 inches above the ground and press the GB pad. While lowering the coil toward the ground, without actually touching the ground, listen for a change of tone. If that tone has a low pitch on the downstroke, the current GB setting is numerically lower than the site requires. When this happens, increase the ground phase setting by pressing the + pad. If the tone is high on the downstroke, you'll need to decrease the ground phase setting by pressing the - pad. Continue to bob the coil and make the appropriate adjustments until you find a setting that allows for the least pitch variation when raising and lowering the coil. After setting the Ground Balance, turn up the Sensitiivty to a point that just barely chatters or creates false signals when you sweep. They turn it down a click to run smoothly. JMHO HH Randy

Thanks for the set-up tips. Ground balance number is always above 6. I'll try this later today. Tom
