Garmin 2010C Review

by | Last updated: Feb 7, 2021

A big 10″ full-featured color chartplotter that is sonar capable and has exceptional resolution.

The response time is good and has an extremely fast chart redraw rate.

It’s very easy to use and an excellent choice for above deck or nav station installation.
