December 21, 2011 (San Diego’s East County) –A great way to secure your valuables, particularly in wildfire-prone East County, is to create an underground cache.  The same methods can also be used to create a survival cache or time capsule. For extended underground applications we recommend our Seahorse line of cases as the first choice primarily because they are the only cases on the market that are truly rust proof.  Even the hinge, latch and handle pins are made in molded resin. This applies to case models SE-120 through SE-720.  The larger SE-920 and SE-1220 do have metal screws for the telescopic pull handle assemblies. Even then, the screws are stainless steel, but still not 100% rustproof, especially underground for extended periods of time.
