So, when I took out the new Talkabout (Model MR355R - catchy, huh?) and tried calling my turkey hunting buddy Bill, who had walked out of the cabin five minutes earlier, I got no response. So much for this unit, I thought. But then I remembered that the new model has a Power Boost button. I pressed it, and damn! There was Bill on the other end, telling me he wasn't hearing any turkeys. The company claims it has a 35-mile range, and while I didn't try to contact Bill 35 miles away, I will say it is definitely more powerful than its predecessor.
