Pro tip: that $180 ground penetrating radar app is a joke, save your cash
Everyone in my local club keeps saying you need GPR to find anything deep, so I dropped $180 on a phone app that supposedly does it. Tried it at a known site outside Tucson and it pinged a "burial" that turned out to be a buried irrigation pipe from the 1950s. My old $40 probe and a good trowel found the actual hearth 6 inches down. Anyone else think these cheap sensor apps are just expensive noise generators?
