Take a little time and check out the Vantage cameras from Wildgame Innvations. They are a Mimi HD camera the comes with all kinds of attachments. You can mount the camera on your hat, bow or tree and has a water proof container that allows you to still film out of. The nice thing is they will not break the bank. My son and I have been testing there AC 5x out for our forum Tips,Tactis, and Gear at
www.bloodtrails.net. The 5x is great, it is lite weight, and fits in the palm of your hand. It shoots video and takes still photos. The only draw back is that there is no view finder or focus button. If you are not wanting to get into the $ 2,000.00 or more range then take a look at Sony Handy cam. They are priced right and you can film in HD but it will eat disc up fast. They have several setting for recording and they to do not take up a lot of room in a pack. You don't think about it till it is to late but filming hunts means more gear to pack in. Go to
www.wildgameinnovations.com and check out the Vantage cameras. Wal-mart has the Handy cameras. If you are jumping in full steam ahead then take a look at Sonys AX 2000 it is a FXHD camera which B & H or Campbells both carry. If I can be of any help send me a PM. At bloodtrails.net there is a couple of guys who have there own shows and they can help you also, you can join up for free. Good Hunting.
