"While I haven't hunted with my new HR230 yet I am pretty certain that I will be pleased with it. I've had a HR200 for many years using it for both deer and black bear. I have lost track of the number of deer I've harvested with the unit and have also taken three black bear. The last one taken in Saskatchewan this past spring, a very wary 470 lb. giant that I don't believe would have come in if I hadn't had my Ozonics. My HR200 finally expired during an "opening week" whitetail hunt this year and I promptly ordered the HR230. As with the HR200 my new HR230 will stay in my pack and I consider it an indispensable part of my hunting arsenal."
