Gopro guru's wanted

Sup all. I currently have a gopro hero 2 (that was given to me a while back) and way bulkier than 4 or even 3. Only time I use is on the water. Mostly used on head strap while diving. I'm wanting to upgrade to a 3 or even 4 but not sure which to get. 4 seems to have awesome features and resolution but don't want to spend more on stuff I'm not going to take advantage of. 4 lighter so less weight on head all day is a plus.I'm thinking hero 3 silver though should be plenty but looking for others opinions.
Also which has worse/bether battery life?

3 and 4 have overheating issues for some peeps

Ment 3+

Personally I would get one of the new Hero 4 models.  GoPro has done a major upgrade to filming in low light with the Hero 4.

Keep using the 2 until it totally dies. Then you can upgrade to the 5 or 6.

Some detailed reviews on this link at Amazon. I'm in no hurry to replace my Hero2.

Thanks for replies. Picked up a Sony action cam for $200. Was told it is comparable to hero3+ silver but we shall see. Have 90 days to test run.
anyone use sony cam instead of gopro?

Nope, but I'm anxious to hear how you like the Sony.  I checked it out in the store and it's a nice cam.

Heat and Battery Life are the 2 main reason I still prefer the GP2...

Seems the smaller they get, the hotter they get...

If you want to fight the crazies on thanksgiving....

I'm just waiting until after Christmas when everyone dumps their brand new GoPro's for cheap.

I was actually in the market for a new camera as well.

If brand name is not an issue, you can give this a shot:

The video quality nearly the same as the GoPro's as well as the specs.

The review:

I still like my 2 over my 3+.  The 2 is simple and the quality and battery life are outstanding - oldie but goodie for sure.
