I woke up to am early B-day presant from my wife. A small box all wrapped up, that I tore open like a seven year old. I was happy to find a maveric et-73 inside. Something I had long wanted. I took in out side to test distance.. Had a range of about three feet, returning inside I tore it apart. 15-20 minutes latter the mod was finnished. I now can get reading from the otherside of a garage, threw tow brick walls, into the house threw three or four other walls. Works fine threw out the house from every room b ut the living room. There it is a littel scechy, but about five feet away into the ketchen it works great. All, and all I am pretty happy.
