Our all new modular Habitat Mats, provide the easiest, tested and proven way to keep a large grouping of fish habitat units and products forever together and heavily weighted to the lake floor. The Eco-friendly and all plastic Fishiding Habitat Mats, allow you to assemble and slide hundreds of pounds of habitat groupings into the water directly off docks, boats, barges and pontoons without the need of heavy equipment. Incorporated grated feet, rails and runners combine to offer unlimited weight disbursement in virtually any underwater terrain, never sliding, tipping or moving once installed.
