I'm having transducer troubles but once I get new HD ducer I'll probally like it. Mapping is slow to load- even when switch screen views then back to map- and no memory card slot- just one for LakeMaster Micro
You can see it looses depth /bottom in video and see how slow mapping comes up. With My 859 I had mapping would be instant when switching views.
Loc: Lake Fork Tx.
Big Poppa, check out Wayne P.'s solution posted on 12/21 in the Equipment forum. It worked for me and is still working. The pins in your power cable may not be making a good connection. Easy fix if it works. Some type of power problem id likely.
