Any input from from the Radon folks for someone looking to add this on to their business?
NRSB does appear to be missing some of the latest new devices, like the Corentium Pro, from their lists.
NRSB is definitally cheaper for certs ($100//1yr, $160/2yr) and exam ($90), but it appears to be difficult to get an exam scheduled cause there is simply no school or university going to allow you to come in there for a proctored test. Also, no real feedback from people taking the exam, unlike the dredded NRPP exam.
NRPP ($220 cert) seems to have some horor stories about exams ($140) too, most seem to pass InterNACHI exam with a 90-95%, but go on to fail the NRPP exam with 55-65%? Then it’s $140 to retake again.
Besides the cost and exams differences, I see no real differences in proceedures. Looking at using a CRM device.
