VIO POV 1 any good?

I bought the mount kit for my POV despite being a bit annoyed that you had to buy all mounts in a kit instead of just the mounts you need. I use the goggle mount for both snowboarding and mountain biking. It's hassle free, just make sure your goggle strap is as tight as you can tolerate to ensure a stable image.

I used the tube mount for my bike to experiment with low down shots (e.g. on the chain stays) to give a better feeling of speed (see for an example). It attaches with zip ties. Once you've got them really tight, the image is solid with virtually no vibration. As an extra precaution, tie the mount to the frame so if it does slip out the zip ties, it won't fall on the ground. The downside is that the mount can only be rotated at 45 degree increments so you only have 8 camera angles.

I also bought a RAM mount in order to mount the lens on the handlebars with more flexibility than with the standard POV handlebar mount. Headcam Guy has videos of using these mounts with the POV on his website. RAM offer all different kinds of mount parts so you can mix and match to suit your requirements but they also sell full kits such as this one which is the kit I bought. They are heavier and bulkier than the POV mounts but much more robust.

As for batteries I use Energizer lithium AAs because they last about 8 hours. Far longer than normal Duracells etc. The big difference, though, is that the lithium batteries are the only ones which work properly in below zero conditions. Normal batteries loose their conductivity in cold conditions and the POV indicates that the unit is low on power. (However they become usable again once back in a warmer environment.) I went boarding in Austria and had run out of lithiums AAs. They didn't sell them at the resort so I had to use standard AAs and in -10 C degree conditions I got through about a pack per day (just a couple of hours filming per pack). A pack of lithiums would probably have lasted me the week.

There are firmware patches on the VIO site which allow the unit to work with 4GB and 8GB SD cards (make sure your SD card supports a high data transfer rate).
