Looking to have an expert install my EchoMap 93SV and Livescope units, to get optimum performance, and it seems all the marine service centers are booked out until June. They aren't taking appointments right now since they are so backed up. However, the Cabela's in Hoffman Estates IL said they could do the install within 2 weeks. Anybody use a Cabela's to rig their boat and were you satisfied? Thanks in advance !!
