Garmin 73sv blurry downvu

[Blazer66]

I have had the 73sv for about a month and all of a sudden this last week the downvu is blurry. I have messed with the setting and played around with the transducer still no change. Does anyone have any ideas?

Can you do a "factory reset" on Garmin? This would put it back to about a medium setting, such as you would have on a brand new unit. Sometimes we change something way down in all the menus, and then can't get back. I'm not that familiar with Garmin, so can't offer much more than a general suggestion.
