I am looking for some qualified advice. I am looking to upgrade my display unit for my LVS32(w/the GS10box). I currently have a 7610 and am going to upgrade to a 12" model. This unit will be mounted on my bow solely to be used for viewing my livescope return. I am comparing the spec numbers of the ECHOMAP ultra 126 to the specs on the 8612 unit. The pixel count is vastly better on the the 8612. My question is the improved picture quality of the 8612 worth the premium price tag it has? Right now Bass Pro has the 126 on sale for 1600.00 but I am realizing the pixel quality of it and my old 7610 are exactly the same..should i just spend the money on the 8612 or will 126 be enough? Thanks in advance..
