The HD Hero3+ camera’s waterproof housing is good to depths of 131 feet (40 meters); the Hero3’s dive housing was good to 197 feet (60 meters).
TrollPro3 can be used with all GoPro Models!
In late 2012, GoPro announced the Hero 3 line of cameras. These new cameras came in three editions: Black, Silver, and White.
All three versions of the Hero3 come in a new 30% smaller and 25% lighter package, with WiFi functionality built in (WiFi will not function underwater). The change of the physical dimensions of the cameras compared to the previous generations (Hero1 and Hero 2 were physically identical) implicates that some of the camera accessories for Hero1 and Hero2 are not compatible with Hero3, so GoPro made new versions of those accessories specifically for Hero3 (and mostly for Hero3+, see above). Those new versions of accessories are usually not compatible with older Hero camera generations. However, a lot of other accessories are compatible with all HD Hero camera generations. TrollPro® introduced the TrollPro3 which incorporated new milling in the housing to allow all models of HD Hero cameras to fit.
In October 2013, GoPro released the HERO3+, available in Black Edition and Silver Edition, which replaced their respective Hero3 generation predecessors. The Hero3 White Edition still remained as the actual model in the low-end GoPro’s device segment.
Both Hero3+ camera models have “dramatically improved” low light performance, and a new waterproof enclosure which is lighter and smaller than the HERO3 (20% and 15% respectively, according to the GoPro website – the Hero3+ camera itself has a 20% decrease in size compared to the Hero3) and are also claimed to have improvements in image sharpness (close focus down to 7″ vs about 3 ft on the Hero3, at the expense of distant focus which is slightly less sharp with Hero3+), and better audio functionality to include wind noise rejection. Battery runtime improvement is claimed to be 30% compared to the respective Hero3 model (both through better efficiency and a higher capacity battery in the same size). TrollPro3 also allows Hero3+ cameras to fit.
GoPro followed with the HERO4. The HERO4 was rich with new features. TrollPro3 and DredgePro easily accommodates the Hero4 cameras.
GoPro now offers the HERO5., the latest in their line-up. TrollPro3 and DredgePro easily accommodates the newest HD Hero5 cameras, along with all previous models.
Many compact sport action cameras are now being marketed that are about the same size and configuration as the GoPro cameras, and utilize the ‘GoPro type Camera Mount’ so that GoPro accessories can also be used with them. Many of those cameras will also fit in TrollPro3 and DredgePro. You should ensure that those cameras provide the required waterproof capability and operating depth before use.
