If you have completed the EFR course with us, you may want to feel you can pass your knowledge onto others by becoming an EFR Instructor. The course takes 1-2 days depending upon your experience level. Remember if you are a PADI Instructor without this you cannot certify Rescue Divers and Divemasters unless they already have the required medical training - you would have to send them to another instructor who can, and lose business!
