Searching large mountainous area

Hello all,

I have narrowed a search down to the side of a mountain. About 1/4 square mile. There are no modern items that I'm aware of so it will be an all metal search. The first item would be steel about the size of a wrench around 12-18", the second item would be steel/tin and gold about the size of a baseball at around 4-6 feet.

Now finding this second item might be a stretch but what would be the best machine for searching a square .25-.50 mile on mountainous rocky terrain for a 8 inch steel item at 12-18"? I have a Garrett AT and an Equinox 800. I prefer the nox but I'm open to purchasing a larger range machine as well. Any ideas? It's also 3 miles up rough terrain so can't be anything too heavy.

What type of ground mineralization will you be dealing with.

A lot of quartz and granite. Moderate iron.

I would go with the Garrett ATX its compact and easy to pack.
I've been eyeing the ATX deep seeker for a long time. I am considering it. I'm also looking at a hexacopter drone with a magnetometer to plot possible targets.

Will do. I'm not far from you. Near foothills of Denver here.

Ya but you know treasure hunters. Secrets and all ;) What are thoughts on a double box detector like a Garrett GTI Eagle Eye? Not exactly light but I could get one up there. Or is it even worth it? Would the ATX cover the same ground and time?

Check this video for reference by Jeff using the ATX with Deep seeker coil.
He's pretty funny, I've watched several of his videos. I may grab the ATX and take a trip up this summer. Thanks!

I had an acquaintance who was using one in a mountain setting not much on depth and mineralized soil really made unreliable on detecting anything. The Pulse Induction is the way to go now they are getting it figured out.

I fly magnetometers on drones all of the time. I use either a Geometrics MagArrow (~$38K) or QuSpin Total Field Magnetometers (QTFMv2). I fly either a DJI M210RTK or M300, or my custom build ArduCopter quad copter. My main application is abandoned well heads or pipelines. I have done terrain following surveys in mountainous areas, but they can be tricky and time consuming. I also put four magnetometers (QTFMv2) on an aluminum carry frame with an RTK GNSS receiver and survey larger areas on foot. I have surveyed an entire island (Wake Island in the Pacific Ocean) with a UTV towed GapEOD UltraTEMIII metal detector array. There are solutions to every problem, unfortunately there are often no cheap solutions to a problem.
