you can get a FoxPro Deadbone for around $99 ... 15 preset calls, but you can NOT add to it....it is what I'll be using this season ... remote operation to 100+ yds... I use AA Lithium batteries in it and in the 9 volt remote and keep and extra set with me... not sure the run time per se is, havnt found any reviews that give the battery life ... the lithiums should have it last longer and work better in the cold ...
