Safety and Productivity Go Hand-in-Hand

IWT offers the best safety and communication systems for mining and tunneling applications. Our commitment is to provide reliable, cost-effective solutions and support for the life of your system.


Our background works for you

IWT developed a communications and tracking system in response to the MINER Act of 2006. Adapting our mesh networking technology specifically to underground mining, our team designed the world's most reliable and advanced wireless communications and tracking system.

IWT first developed the ACCOLADE® system while working with L-3 Communications. In 2012, IWT purchased L-3's mining business and now supports all ACCOLADE® systems. Soon afterward, IWT released SENTINEL, the next generation of the ACCOLADE® system. 

IWT’s Mine Safety Communications and Tracking solution is the standard we will measure the other manufacturers by”

SENTINEL handsets, tracking beacons, and MML (locators) all work with existing ACCOLADE® systems, and all SENTINEL system components have been IS certified.  

Since that time, IWT's innovative engineering team has been working with the mining and tunneling communities to expand the feature set of our systems to solve safety issues and leverage productivity.
