The new Hero 3+ is purely visual, with the previous Hero 3 exactly the same. Only the housing has changed, somewhat smaller, "only" to 40 meters water resistant, and the safety lock was omitted. The battery lasts really a little longer, you can schedule 2 hours per battery. In addition, it is now possible with the Edition "Silver", also in 1080 to film with 60 FPS, instead of just 30! I like that person very well. The WLAN function by APP has become much faster and now also useful. The delay is my iPhone 5, just 1 second and is therefore now acceptable. One can also means the app the same watch videos, start shooting and control the Photo mode. The picture and sound quality has always been very good in my eyes and now become even slightly better. Night shots unfortunately I could not test. The accessories are suitable to the housing itself, also the new Hero 3+ The difference in price of Hero 3 Silver for Hero 3 Silver + Edition, is currently at about 100.-
Conclusion: The change of the Hero 3 on the Hero3 + is not worthwhile in my eyes. But if you want away from the Hero 2, for bringing the Hero 3+ much new with. Even those who still has no Hero, should choose in any case in the Plus Edition Camera. The Hero 3+ Black Edition I personally find excessive, who already filmed in 4K. The remote control can also receive by app, or buy it. Here I would to "Silver Edition +" advise!
