THIS IS MY THIRD ONE . FIRST ONE WAS PROBABLY MY DOINGS . THE MOTOR WAS NOT CHARGING AND IT WOULD RUN BATTERY DOWN QUICK . AFTER LIKE THIRD TIME IT WOULD SHUT DOWN AND NOT COME BACK ON . WELL DIDN'T FIGURE OUT HOW TO RESET IT TILL I HAD TOOK IT BACK . SECOND ONE WORKING DECENT AND IT JUST QUIT SHOWING THE DEPTH . I ALSO FIXED MOTOR PROBLEM AND REPLACED ALL BATTERIES . AND NOW I HAVE MY TWO DEPTH FINDERS ON A BATTERY BY THEM SELVES . TOOK THE ONE BACK WITH NO DEPTH SHOWING . GOT A NEW ONE AGAIN . THE DEPTH COMES AND GOES ON IT . I HAVE CHECK ALL MY WIRING AND CHANGED THE TRANSDUCER AND I JUST CAN SEEM TO GET IT WORKING . I HAVE BEEN OUT THERE REDOING THE WIRES AND I JUST DON'T KNOW ?
