Drain Oregon Weather Underground

recommend spare back up battery for cold weather battery drain & about the time you want a shot---the battery is dead.

I used this product because it is less drain on my camera battery

Used it during the family vacation to Oregon. Definitely worth the money.

I have several 3rd party batteries and they drain way faster than the Sony. I will only use these batteries going forward.

Love it so much, did not experience any noticeable battery drain while sitting.

take a bit of calibrating - it reaches further and less drain on flash batteries.

Love it. Used it on a vacation to Oregon all my equipment fit in. It it was nice to have one case with all my equipment.

Great vest. I'm using it in an underground coal mine. It's like having an extra pair of hands. It distributes weight evenly. I use it for batteries, flashes, all sorts of accessories. There are no pockets for big lenses, but that's O.K. It would make the vest too heavy and cumbersome. It's pretty good at repelling lime and coal dust and water and is not likely to tear easily. Pockets are lined with soft material, which is easy on lenses. These vests are a little pricey, but worth it. They're professional gear and are made for rugged use.

Solid takes abuse perfect for poking the gopro into strange places underwater and underground.

So far so good! Using as a backup power supply for an underground dog fence and so far is working great.
