Divesite:

Since its intentional sinking, the Lowrance became one of the most popular tech diving sites in all of south Florida. Named after the manufacturer of recreational marine electronics that donated funds to help sink the vessel, the Lowrance sits in approximately 200 feet of water. The hull of the former freighter provides significant vertical relief, with the main deck found at a depth of 165.

Found approximately 2.5 nautical miles outside Hillsboro Inlet, the Lowrance rests perpendicular to the generally northward‐moving Gulf Stream; even during periods of significant currents, divers usually have no problem hitting this massive target. It is also worth noting that the wreck of the Renegade is found approximately 700 feet due north of the Lowrance, should divers find themselves on the bottom and in between the two artificial reefs. The midship area is perhaps the most interesting, though the remaining upper decks have experienced significant collapse in recent years. For divers with the requisite training and experience, the wreck of the Lowrance offers a fantastic circuit through the engine room. Divers can enter through a hatch on the main deck of the vessel that leads down a hallway, eventually opening up above the engine room. Gorgonian-choked skylights above allow ambient light to trickle down onto the catwalks that line the perimeter of the room. Dropping down, divers can work their way around equipment, eventually exiting through one of several large holes cut out during the vessel’s preparation for sinking, or via a smaller hole produced by the explosive charges that sent the former freighter to the bottom.
