In response to the more stringent acquisition requirements in today's marketplace, the L-10AR digital grade geophone has been ruggedized to withstand the rigorous demands of hostile field environments and meet the rigid test parameters of the most sophisticated geophone analyzers. The L-10AR has been updated using the strictest manufacturing tolerances and procedures, advanced technology, and the latest materials available, yet retains the features that have made its predecessors a leader in the industry for the last quarter of a century, including a spurious-free band pass to 250 Hertz and the Amphib land case, which includes a sealant-free, molded header.
