Greeting on_two_wheels and congrats on attaining your Rescue!
It is my experience that Rescue is the first step in reaching past the buddy system and broadening your awareness. One very important consideration is to keep the information fresh and stock some of the tools required to perform a rescue.
I have come to appreciate the value of the coarse not just for emergencies but it brings an awareness to the table that will be needed in the future if your dive goals take you into the advanced / Tech realm.
Rescue is a very serious certification and when you use your skills for real, it becomes even more focused. I have been challenged to continue into some even more diver rescue training, DAN O2, etc.
Rescuing am OW single tank diver and a Tech doubles diver are really different.
I have been pondering the class and see it coming in the future.
Congrats and go volunteer! I have learned tons of information from being available to help, assist and volunteer. It can be very rewarding.
CamG keep diving....Keep training....Keep learning!
