how deep you can detect???
639777
The AT Gold comes with the 5" X 8" stock coil. I find I can go down to about 6". I purchased the 8 1/2" by 11" coil, this one goes down 10"+.

I have used it to find an iron pipe about 18" underground. Sometimes it would lose track of the pipe and then pick it up further down the line. Not sure why this is. If it could only find exactly where the leaks are it would really be amazing! Unfortunately, metal detectors are not designed to locate leaks, they just locate the pipe which is a big help. I have found three leaks in an old irrigation system thus far but the next one is still eluding me. There must be a leak as water is going in and not coming out. It has also picked up miscellaneous things a couple of inches from the surface located while searching for the pipe. I have been very pleased with it especially given the price.

It depends on the size of the nugget, but for small or normal size nuggets and a 6" coil expect about 6". You can put a larger coil on and that will get you deeper detection (a foot or more) but it will be less sensitive to smaller nuggets.

About a 12 inches on fresh batteries in average soil. Sand and mineralized dirt make a difference on depth also ...Really if you get a reading around 6" then rescan again after digging down 6" it will go deep as you want...

As David and Chris said, you have to be close, if the big detector signals item is shallow I will poke around with this to try and locate, but other wise I dig a hole and use the pinpointer to help locate.

Not sure, never really paid it much attention, but should be about 2 to 3 inches deep. If you move your mouse over the picture, you can see how deep it is, picture is pretty much true.

You do have to be pretty close to the wire for the sensor to pick it up, so I don't think it would detect it at all underground. Besides that, even if it could, it's not designed to clarify where an abrupt end to a signal is, so if you lost the signal, it could mean the wire is broke or you are no longer following the wire. Bottom line, this tool is not the way to resolve your problem.

It's mounted 7'-10' high to be detected maximum distance up to 60'-70' (@75F or less). if just detects 10'-20' away that have to adjust sensitivity knob via clockwise to increase its sensing range.

Not sure, I'm a beginner with experience with a cheaper brand. After using this model I must admit my old metal detector "toraso cultus" is much easier to use and detects just as deep. I'm not certain the price gives me that much more of a detector. I'm still learning it but am becoming a little frustrated.

About 8"~12" in good soil with a fresh set of batteries...larger objects tend to read deeper... Example I dug a paint can lid about 15" deep once...

I have mine mounted on my House overlooking my Back Deck . My deck is about 16 ft. in Depth and it detects movement at about 12 ft .

depends on proximity. (the more ferrous mass the longer distance it will detect. less mass need to be closer)get detector as close to travel path as possible.

Hi. General Tools indicates that it CAN detect moisture up to 4" deep/down. * Spherical sensor gauges moisture level up to 4 in. below a surface. I haven't used mine in that capacity yet so I can't tell you from an applicability standpoint. You can also check out other specs here: http://www.generaltools.com/assets/images/Manuals/MMD950ManualGT.pdf Hope that helps!

Depth is determined by several factors. Size of target, metal conductivity, mineralization of the soil, and coil size. On this particular detector for example, a coin size object can could be detected at approx. 6 to 8 inches.

Well Gabriela, I am just testing my machine out, but I did locate a dime at over 8 inches. However, obviously the depth depends very much on the ground conditions.Hope this helps.John

I think about 6-8". It's not a professional metal detector, but it has not failed us.

You cannot see the shape of the target on the screen, only a bargraph indicating conductivity and a grid showing approximate size and depth. The maximum depth that it can detect is about 1/3 of a meter.
