The 320 acre field took me about a month, 4-6 hours searching a day for one 39lb meteorite. This field is north of the main strewn field but you have to search areas with no meteorites to know where the strewn field stops.
Keep those questions coming! Don

An acre is 43560 square feet. The sled is 12 feet across, with overlap, about 10 feet wide per pass. To cover one acre you drive 4356 feet = 0.825 miles or 264 miles for a 320 acre half section. At 7mph this takes 38 hours. However, this is not the whole story, digging up trash, signals that sound good but are not meteorites is the rate limiting step for me. The more junk in the field, the longer it takes.

More questions: the thick black cable attached to the sled contains 8 loops of wire, it is a coil with 8 turns. The coil is pulsed and the decay of em field is measured, metal objects prolong the decay.

I always look forward to your videos Don, very informative and detailed. I think I saw some of this on msnbc under space videos the other day. The meteorite men got nothing on the mighty DS. lol. Take care dude! Thanks for another great vid!
