HoundDog is built with new hi-tech Fence Ignoring Technology (FIT). The HoundDog can sniff out those hard to find survey markers under fences and around metal buildings.

The HoundDog works great with ChrisNik's Magnail, MagSpike and MagHub! Our new HoundDog locator with its patented technology will quickly become your best friend!

The HoundDog can find the positive (+) polarity at the top of ferrous metal  objects while ignoring the negative (-) polarity found at the bottom. This allows the HoundDog to ignore the bottom of a fence and easily find the top of buried magnails, rebar or other ferrous survey markers.
