I am leaving Monday for the panhandle of Florida for 4 days of beach hunting. We will hunt the water during the daytime and the dry/wet sand at night. This will be my first time hunting the beach in over 30 years of MD'ing. I am excited and I am expecting good results with the CTX. My question is what mode do I hunt in? I know to use an open screen, but is the a difference between beach mode and coin mode with an open screen? And what about deep and recovery settings.I understand about reducing the sensitivity in manual if needed. I have my Gray Ghost waterproof headphones for the water. All help is greatly appreciated.
