For Today's Teams

Today’s HAZ MAT, Confined Space, Swift Water Rescue and SAR teams are tasked with more responsibility and quicker response times to lead a successful rescue.  One of those advantages that we can help with is in the area of rapid communication with your team.

Ever been fully geared up with your HAZ-MAT suite, SCBA or crawling in a tight crawl space and wish you had a means to communicate hands free while working within the scene?  

Well now you can, thanks to a recently patented technology that allows for full-duplex, hands free communication with up to 3-people speaking at one time.  Unlimited users.

3-People Can Speak at the Same Time
Unlimited Users
2 Year Warranty


In 2014, this system was developed in conjunction with the French Fire Brigade and their HAZ-MAT, confined space, swift water rescue and SAR teams.  What they were challenged with was what many of you are faced with when needing to use their hands while communicating quickly and timely.

Now that the radio system has been vetted in Europe we are launching the communications program here in the USA.  

Featured Products

Though rescues are similar in situation, the needs of you and your team will likely be different than what is practiced overseas.  So we want to work closely with you, understand the gear you wear, the training you undergo, the situations you may encounter and make sure the combination of ear bone mic with speaker or special headsets accompanied with a water proof APPI-Com radio are exactly what you need.

Please call us and we can configure an evaluation unit for you and your team.
