Just to let everyone know. I have a 898c humminbird and have had it for almost a year now. I had a small pen size dot on my srceen. kind of like a rock putting a small nick in a windsheild. the nick on my screen was not a hole and had no effect on the unit other then me being mad about it because of it costing so **** much. anyways I called humminbird was thinking i was going to have to have some big story for them. I was on hold for about 10 mins. then when they got on the phone it took not even 5 mins. I had a case number and they had told me to send it in. it cost me $19.90 to send it in. my unit is fixed and as long as humminbird doesnt change this service they have found a life long customer.
