Part Number: 010-00150-00


The Garmin® GPSMAP 185 Sounder offers unique functionality to the fishing enthusiast who wants it all. It boasts a generous display, a small footprint for space-challenged installations, powerful 12 parallel channel GPS performance, detailed digital chartplotting, and a 200 KHz sounder/fishfinder.

As for the Sounder, single-frequency operation lets you keep an eye on both deep and shallow water, a variable zoom window shows details at the touch of a button, and an exclusive underwater waypoint capability allows you to store the position and depth of objects below the water's surface.

Garmin's reputation as a navigation leader is evidenced in the GPSMAP 185 Sounder. Accurate 12 parallel channel GPS position information is displayed on a big built-in basemap, and Garmin micro G-chart cartridges give you even greater map details for inland or offshore operations.

Despite all the capabilities of the GPSMAP 185 Sounder, it remains easy to use. Uncluttered and intuitive, it has the distinct look and feel of a winner.
