Default Tell me about resolution

Looking at a Simrad Go9 and a Garmin GPS Map 842 and trying to decide between the 2.

One of the big differences is in the screen resolution.

Simrad is 800 x 480
Garmin is 1024 x 600

How much of a difference does this make on a fishfinder - specifically if I will be running a 3 way view with sidescan acorss the top and regular and downscan split along the bottom.

Will the lower resolution offer enough detail when split like this?

The Simrad resolution is not bad for a split screen, but more resolution never hurt anybody. I believe the Garmin has a different aspect ratio on its 8 inch screens, which will affect how it splits. I think you should really try to see one in person. I'm not exactly sure which model your referring to when you say 842
