IWT's SENTINEL™ Mine Rescue system was developed to meet the rigorous and demanding specifications of mine rescue teams. As a result, mine rescue teams are moving faster, safer, and more efficiently than ever before.

Replacing legacy sound-powered or walkie-talkie handsets, the system enables constant communication among the exploration team members, the briefing officer, and the Command Center. 

Small, lightweight, rapidly deployable Portable Mesh Nodes (PMNs) are the heart of the system, acting as repeaters that establish a robust wireless network.  The mesh nodes join the network automatically – no IP address needed.  Just turn them on and go.  Scale the system from inby the Fresh Air Base all the way to the surface Command Center by dropping PMNs outby as the Fresh Air Base advances. 

Handsets provide crystal clear voice for anyone on the network.  Speaker mics, single or dual muff headsets, and direct connection to the SCBA facemask are options to facilitate communications.  Furthermore, all communication is encrypted to maintain security.  Handsets are also tracked by the system. 

 The IWT Mine Rescue System comes with 24/7/365 technical support in addition to training and service plan options to maximize effectiveness.

Virginia now has the best in communication with the purchase of an IWT system thanks to grant from the Mine Safety and Health Administration. The system syncs to MSHA's. In addition, the mine rescue team has added R-2 to their ranks for quicker response time.
