There are plenty of operators who are not CAMTS. And IMO, camts is a joke. Its designed to make sure EMS pilots are safer, but it only encourages people to lie on their resume.
CAMTS is the HEMS equivalent of school teachers 'teaching to the test'. The students pass those all important tests; the teachers/schools look good, but the end product isn't any better than before. CAMTS doesn't make an operation safer or better.
