Model 400-001 has been discontinued. Please see suggested replacements: Model 400-005 and Model 400-006. RigCom Stations are a common-talk communication system designed for hazardous and harsh environments. The system is simple to use with push-to-talk, release-to-listen operation. The station can also be configured for hands-free operation where the speaker is always in listen mode. The RigCom station consists of an explosion-proof case, which houses the electronics, and an explosion-proof loudspeaker that also functions as the microphone.
