Sent my 705 back to Kellyco because some of the numbers and letters were missing at certain times. They fixed it and sent back. Seems like it is not right !! When going along it will make a beep but no numbers show then when I do get a number say maybe a 42 when I go to pinpoint a -8 will come up and I will never find the good number?? I own a etrac so I have only used my 705 a couple times. Always before I never had this problem what do you think...I checked my coil connection and it was fine!! Does it need to go back in?? Thanks for any suggestions you all might have.....
