good evening johnny2 yes it is programmable from your own home computer.I just bought it in 2006 it holds 32 sounds,you can change sounds,the order they are in and everything its great.I am not a salesman but check out their website you can sample their entire sound library.I also crow hunt with mine it works great.I have shot some sitters at about 150 with my trusty 5mm rem mag and several with my ruger M77 markII 223 IT'S GREAT TO TALK TO PEOPLE WHO SHARE THE SAME JOYS OF THE OUTDOORS .thanks coyote#68
