Question: Do I have to buy a separate waterproof case to fit the LCD touch back pac?
Document: This &#34;combo&#34; includes the Hero 3+ Black (with slim housing) and LCD Touch Bacpac #ALCDB-301 (for Hero 2/3, so housing back doors are not compatible w/ the slim housing). It should have included the Bacpac #ALCDB-303 to be compatible. The description excluded this critical information, so I assumed that surely the &#34;combo&#34; would be compatible -- but it wasn't.
Having always been something of a camera buff from back in the day, I was intrigued by this camera once my daughter waved hers around with high praise! It does all of the normal pic/video things...but in high-def and a whole box full of accessories. I purchased the camera, a carrying case, and every accessory available for this camera. It's the 'cat's meow' and I can't say enough about it. Buy with confidence.
It just comes with the back doors for the older-style housing, which don't fit on the newer slim housing). Very disappointing to be misled and overcharged.
This all purpose action cam/camera is amazing for its ability to film every way, everywhere, and everything I use it for filming my fishing excursions. everyone should own one of these bad boys, you won't be sorry
Right out of the box it was inop. Had to send it back to GoPro. They were good about replacing it but been without the camera while they check the bad one first before sending me a new one. No need for that just gety a new camera that works.
This product is great- allows me to do all kinds of fun videos underwater. Perfect for travel. Wireless remote works great.
Answer: It should come with 3 different case backs. 1 for land use (allows use of touch screen, 1 water resistant (allows use of touch screen) it is meant for use around water and 1 water proof case (no touch screen) for use in and under the water. The 2 water backs can easily be confused. Make sure you mark them some how. Believe me I brought the wrong case on a dive trip.
