Hi All, New member here, do not know much about electronics but I am a powered parachute (two seater) pilot and an amateur prospector just wondering if anybody has any suggestions on which kind of magnatometer would mount on a powered parachute (example at www.powerchuteuniverse.com) Ifly at approx. 28 mph and capable of flying at 50 feet, with care. Any suggestions would be appreciated. Thanks.

flying a mag
Geometrics has customers with a G-858 and GPS flying them in larger RC planes; it is kind of necessary to convert the batteries to li-po packs.
I have a G-858 listed in the for sale section (with a li-po pack) and will be putting it on eBay in several hours.
Will add a link when up.

I have only seen one unit used from the air. It was a JW Fishers Proton 4 and was attached to a helicopter. It did work very well and seemed to cover a lot of ground.
Might be a bit much to attach to your rig. But you should check it out.

I am also a pilot of ultralight aircraft. Welcome on this forum.
The problem to embark a PPM on an aircraft is the large magnetic mass of its engine as well as the large electromagnetic distrubances it generates.
All the PPM carried by real aircrafts are attached to a long cable and powered and controlled from the inside of the aircraft.
Also, you should use a light, VERY sensitve and very fast mag to detect anything at 50ft and at 28mph. That obviously calls for a cesium mag.

at this very moment i am have 2 crews doing mag and spectrometry on quad bikes.
i am using a 3 meter aluminium ladder with the mag sensor at the very far end of the ladder.
the ladder is mounted at the back of the quad bike.
Spectrometer in the front
i am using 2 GemSystem GSM 19w magnotometers and one Gem Base recording at 1 second per reading ,base mag recording every 5 seconds.
travelling 15-20km per hour in the desert (Africa)
i am simply using the gps system built into the magnotometer to record position, using a simple hand held gps for navigation
the data is excellent although be prepared to do a little levelling on the data.
i have to add 28 nt to the lines that run North .. i have to add 2 nt to one of the quad bikes because one has a little extra metal.
you need to purchase good geophysics software .. i am using Oasis Montaj
everything is isolated with rubber .. vibration is a no no
it a lot easier then i expected to get good quality dataComment
