Our Mission

We recognize the need to modernize and improve the capabilities of in-cave rescue communication. We also understand the need to remain compatible with current 2-wire systems.

Our mission is to develop communication products that allow cave rescuers to enhance and expand their communication capabilities while maintaining backwards compatibility with currently deployed systems.

To that end, we have developed two products: ECHO Bridge and ECHO phone. The ECHO Phone is a light-weight, compact replacement for the TP-6N field phones. The ECHO Bridge allows for the seamless connection of wireless radios and cellular phones to the 2-wire network.

TP-6N Compatable

ECHO products are specifically designed to work with traditional 2-wire 'cave phones'. Every ECHO product has the same capabilities as the TP-6N including

  • Two-way communications
  • Remote phone ring
  • Determine if other phones are on the network

Interface with Modern Devices

The ECHO Bridge allows you seamlessly connect any 2-wire network to a modern communication device including wireless radios and cellular phones.

Who we are

Three brothers with backgrounds in technical cave rescue, pre-hospital emergency medical care (paramedic and emergency medical responder), electrical engineering, aerospace engineering, and computer artistry. Born in rural Illinois, but scattered across the country, we love to come together and create.

We are the Schweighart Brothers.
