hI.i ever made the reset, detph readot appear when the beam is on the water but give a big number whereas the depth is less important, before 2554 feet, now 1550 feet with only 75 feet real, and is lighting, si and down imagine seems to be ok.
I set the upper range oft and try différent low range but the number always lighting and stop by intermitence.Isn t that the beam that doesn t work any more?It s difficult for me to repare because in guadeloupe, nobody is reparing humminbird model.
Don t know what to do, i was happy to use my humminbird, i steel have the gps and chart reader but need all the rest.Thanks
