I bought a Humminbird 899ci HD SI and did the exchange for the XHS 9 HDSI 180 T. It has been bad weather this week so I have been reading and trying to learn everything I can this week about my Humminbird unit. I did use my sonar last week some and was real impressed with it. I was using the 455 khz setting and have not tried the 800 khz as of this time. The question I am asking is has the whiteout problem been fixed by now as all the information that I have read was back in 2014 and was it all the Humminbird units. I am hoping that my new unit will not have this problem as I have just bought it and updated the units software. If it does do I have to send everything back to Humminbird including taking the transducer back off of boat and about how long will my unit have to be gone to fix the problem. Paranoia about my new sonar now. Don't know when I will get back on water to test and see if my unit has this problem has anyone had this problem lately? Thanks for all your help about this in advance.
