The Heater Body Suit is no gimmick. Been around for years. Had mine for 5 years or so now. Pretty much a necessity in Canada for those 20 below sits on stand all day. Jim Shockey swears by them as do many other tv hunters. I really like mine. I was not trying to offend anyone about the spamming. I frequent this site and read the threads. Have been for some time now. I decided to post about some cameras I discovered and was accused of being the guy building the cameras. That is why I post very little here now. Not the way to welcome new forum members. JMHO!!!
