Hey guys. I got certified over winter (diving in a pool and hot springs), and I want to get diving this spring hopefully as soon as possible. Our local lake has finally melted off and the water temp is about 40 degrees Fahrenheit. I have an adequate exposure suit based on times that I tried it out in water similar in temperature to what the lake is now. My regulator is also a cold water rig (Sherwood SR 2). I was just wondering what problems I would run into in this scenario.
