Title: Failure to correctlly find steel mesh or rebar under the concreet
Review: i attemted to locate steel or wire mesh under my concrete deck around the swimming pool deck. The Zircon unit gave false signals. I needed to ground a stainless steel ladder and a guiding stainless steel post that extended into the pool for three feet. I drilled several holes past the depth of the concrete(arriving at dirt); but still no metal.I sunk several 8 feet ground rods into the ground and connected the steps and the guiding post with number 8- copper wire.
Is the review positive or negative?
