They're not dippers. They have ground penetrating radar units mounted to their bellies. Here's more info on the tech being used from Popular Mechanics...
Popular Mechanics? Oh please.... If they have ground penetrating radar then they are not sub hunters. Source, 12 years in the Fleet Air Arm working on Sea King and Merlin sub hunters.
They may not be sub-hunters fren. I'm a civilian. These helicopters uncovered a few tunnels while building the wall. I live in Texas and it was a big deal in the local news when they found and destroyed them. One of the tunnels came up under a house in a subdivision in McAllen Texas and the tunnel had lights. fans, and a train car of sorts. I think they found another just like it in El Paso. The Germans invented GPR a long time ago and I bet the Brits have it too.
