Hi folks,<br /><br />I have a problem with the fish alarm.When I want the fish alarm to turn on between a given range ex. from 50 feet to 100 feet,what ever is above 50 feet the alarm won't go on as supposed but it will, deeper than 100 feet.I've tried it on manual and on auto,with the same results as above.<br />Is there a problem with the Furuno?<br /><br />Thanks
