x-terra problem

[crow-duck]

I went out today and noise cancel and ground balance and hunted for about 2 hours and walked to a field about 100 yards from where I was hunting no power lines started to detecting and about 15 minutes later the 70 started to go crazy flashing all different numbers and and giving false readings so I shut it off and turned it back on and it did the same thing.I even turned the sensitivity down to 20 I turned the ground balance all the way up and all the way down and the tone stayed the same.Is my terra sick.

If using coil cover, remove cover and check for sand/soil. If not, change geographic location, and/or a different coil & batteries.

I was using the X-70 and the 18 freq DD coil. My X-50 with stock coil was not bothered. I was at the lake, hunt along the beach. 3 hrs later what ever caused it quit.

It's happened with my X5 and all it will do is give a rapid sputter.
With the Xt and Explorer it was the nervous digits and sputtering. I have turned around and walked right back out of it a few times and sometimes you have to go to another site and come back later. I've done that quite often and the machine run great.

Exactly the same has happened to me.

I was using the elliptical DD 18.75. When I changed coils it settled down.

was thinking I had ruined the coil since I hunted in wet grass the day before but I think the thing is registring all kinds of electrical noise and radio noice.

My X-70 with the 18.75 coil did this a few weeks ago in the dry desert and I think that it was the static electricity from touching the dry grass and sagebrush. My 10 1/2 " DD coil worked OK and the 18.75 coil worked OK when I used it in a damp climate. Maybe there is a problem with the small 18.75 DD coil in dry conditions.

It is also possible to get interference from Aircraft comms.

Your 18.75 khz DD coil should work very well in dry conditions I would say something else was causing the issue. Sometimes when it comes to tech there can be many things that cause minor problems. Hope all things work out for ya Steve.
cheers!

I have experienced high, sort of , altitude jitters when I went detecting on some really high hills. I was smack between 2 transmiters.
The higher up the worse it got. Have experienced it after that at a few places but not as bad. It was always at altitude though. Same thing used to happen on my Whites Goldmasters, except the GM3.
When trying out my new 10" round dd 18.75khz coil in my backyard to see if it is ok, I live with the bush and diggings right out my back gate, it was picking up electrical interference and going nuts on high sens settings. The ID readouts were going all over the place. Yet I can put the elliptical 18.75khz dd on in the very same spot and crank it up to 30 and its as stable as anything. The 10" round has a bigger feild and is more sens to interference in places.

Thanks for all the thoughts everybody. The field I was detecting in, is directly under the landing pattern of the airport, although I don't recall any aircraft flying over at the time. There may have been, but I wasn't noticing.
I've contacted Minelab and talked to a technician there. He seems to think that it may be a bad coil, or the mother board will need replacing. So I'll be sending it to them after ANZAC Day and hopefully have a detector that works in a couple of weeks. It turns out, that the previous technician didn't even look at what I had asked him to do. So if it's the coil, then it's going to cost me a couple of hundred that it shouldn't have, as it was under warranty at the time.
