Received my Garmin Xero C1 yesterday. So far I am super impressed. In the box was the unit (about the size of a gopro), a nice short tripod, and a USB cable. No case, but you really dont need one. I could see throwing this in your shooting bag side pocket and never knowing it's there until you need it. Functionality is super simple and it records EVERY TIME. They say it wont work for shotgun, but I'm going to try it tomorrow. Cant speak for battery life, but I think it could outlast a long range day. If you needed more battery, a cheap external USB battery pack would be fine. You can attach it to your Arca rail via the $165 Area 419 attachment, or buy Leftfoto parts from Amazon and build one for $37. The iPhone app pairs perfectly and you can reference all you data easily. I have a Magnetospeed and will probably never use it again. Never wanted a Labradar due to the size and I think the only thing it could do that this won't is BC. But really any BC (published or labradar) is only a starting point anyway and wont be the same as velocity decreases. In my opinion, this is a Labradar/Magnetospeed kill shot. No wonder there are so many for sale now!!!
