bought my 788ci two week ago. used the mark button and the system rebooted. called hb they told me to send it back for repair.so i wanted to take it back to gander mtn to get a exchange but they no longer carry them. this suck! buy a brand new 788ci and it needs repair! when my fishing trip is two days away that is the reason i spent all the money for my fishing trip vaction .called hb back to see if i could get alittle discount on a788cihd because that is what gander mtd had in stock. told me no.
