I have had my Fortrex for about 4 years now and since the day I got it when placing it down it hangs up some how and does not lock in place. I just push down on the head a little then it locks into place when in the water. I have tried taking a file to the 2 black wings that retract when pulling on the cable with no luck. When I have to push down on the head to lock it in place the TM makes a thud sound because it did not seat into the base all the way. Have any of you guys had this happen ? My Humminbird 360 helps with this because it makes the shaft a little heavier.
