GoPro cameras.

My Hell-bent-for-leather 14 year old grandson has one. The Go-Pro Hero. He uses it as a helmet cam on dirt bikes and motocross. Mounts it to his skateboard, and other things he rides. I bought him extra batteries, a charger and a 32gig sd card for Christmas. He likes it and hasn't broken it yet. I don't know the quality of filming it does. Jim

The GoPro cameras do not have a view finder. They are designed to be mounted in places where you couldn't look through it if it had one. So to answer the question of how do you know what is being recorded, you use the wifi connection and your smart device / phone. The new ones have wifi.

Thank you for that information. Most helpful.

It seems the new ones (Hero 3) have wi-fi.....so you can use a remote or a smartphone app.

The H3 housing also has a flat lens, compared to the older housings.

Those seem to be two big +'s.

As to the no viewfinder on it, you can actually add one if you like. Runs about $69 but I have seen it on sale as low as $50 a few times http://www.youtube.com/watch?v=VSwa0P-Kpp4
