"For confined space rescue and other related USAR training requiring hard-line communication we use exclusively Con-Space equipment. For our Confined Space Rescue operations the Con-Space Kit 1 with Scott Comm-Links provide simple reliable communications at lengths that far exceed our respiratory protection limits. For victim assessment we have used both the talk box module and rescue probe with great success. Years of use in both training and actual events have proven to us that “Con-Space” is the undisputed gold standard in hard-line communication." -- Kent Freeman, Captain, Roseville Fire Department , USAR Task Force 7 (Owner: California Health & Rescue Training)
