While it may not be the most practical method of stashing your firearms, ammunitions or your emergency stash of SPAM, the BuryBunker ($400) has the quality construction and rugged appeal you can't help but like. Made of durable, powder-coated, 10-guage steel, this underground storage safe comes with a lid equipped with watertight silicon gasket and 7/16-inch fasteners. Additionally, the BuryBunker is designed to withstand temps as los as -60 °F and hold a pelican-type case.
