I recently got the Garmin 250C fishfinder.<br /><br />Unit seems to work great "except" there is barely any sound when I get alarms.<br /><br />My boat is pretty quiet and you can barely hear it beep while standing behind the wheel.<br /><br />Garmin says its normal and that I can hook up a speaker to it.<br /><br />Does this sound correct? It cant be.<br /><br />Thanks!
