Can I cast with Rodfendr on my rod?
This is totally up to you. You can cast with it on, Rodfendr is designed to allow the fishing line to easily ingress or exit the device. When casting the line will exit Rodfendr and allow you to cast in a normal fashion, if you are concerned in any way simply turn Rodfendr to the opposite side of the blank and cast normally. Remember to return Rodfendr to its' normal operating position afterwards and place the line inside Rodfendr to protect it. Rodfendr is designed so that your fishing line will easily enter the device.
