Does any of this relate the depth capabilities of an OKM ?
I have had little time with an OKM, but some with the comparable Nokta. Neither one can reach the depths claimed. I had long and unprofitable conversations about this with John White at Kellyco. Kellyco will give you second hand references to capabilities, depths and such. All are from factory sales agents. No one at Kellyco has ANY field experience in using a Nokta or a OKM. This revelation was only after several LONG phone calls and hard questions asking for data. The only field experience the Kellyco people have had was around the lot at the Kellyco business. Factory sales and dealer reps came to the facility and demonstrated the units to the staff. That is all. JW kept repeating the same claim, some person found a pot of gold coins at a depth of 60 feet. But, that is what the factory rep told him. I spent a month on Bohol with a Nokta and I feel somewhat confidant in what it can and can not do. I am going back next week for another month there with the same unit. If you find a strong box at 12 feet, consider it good but highly unlikely. The unit routinely missed city water mains, steel pipe, and city sewer pipes. Those should show up as hollow cavities like a cave. But no luck. However we spent the better part of a day scanning a dry rice paddy and found some strange items. One was detected as an "alloy box with cavity inside" WOW. After digging down 18 inches we found an empty aluminum cigar tube !!! WOW it must have been 50 years old because my DAD used to smoke the same cigar and tube in the mid 1950's. We have also found rodent tunnels at 18". So there are a lot of factors that go into all of this. All of these units misrepresent depth measurements. Read the factory manuals closely.
