I am looking at getting a GoPro to record some of our adventures. The part I like best is the ruggedness of the product. I am not sure if I want the 3+ sliver or the 4 silver. It looks like the 3+ has better battery life, but the 4 has an LCD screen. Also, the 4 has a different battery so if I buy the 3+ I will be getting a product that isn't the newest version for accessories. Any help would due appreciated. Thanks.
