Hi folks,
If I had a 858C, could it be upgraded to a 898C-SI by the addition of the 3 beam transducer and a software download? The reason I ask is that I found a pretty good deal on a new 858C and if I can do this it would give me some extra goodies that are included.
I am just guessing that the "innards" of the 858C are the same as the 898C-SI, but that may not be true?
Thanks,
Ron
