HDS-12 Gen3 is rated 4.6 out of 5 by 103.
Rated 4 out of 5 by from Outstanding Customer Support/Service Purchased the HDS-12 Gen 3 for use on a new boat for Ocean fishing off the California coast. Previously owned a Lowrance for fresh water and counted on continued high standards! So far the Unit has performed well and outstanding navigation function. My Sonar function has quit working and Customer Support has been extremely helpful in trouble shooting the problem, even sending me a new Transducer to try ! They have been extremely helpful with suggestions. Hopefully it will be something simple but they seem to stand by their products!! If they continue to back their products I will be purchasing the companion Radar System. I would have given them 5 stars except for the Sonar failure!!

Rated 5 out of 5 by from Outstanding graphics...Easy to Use While you have all the options you need to "fine tune" every setting on every screen...it works great right out of the box using the factory settings. The extra large screen provides the ability to see even the smallest of detail and the touch screen is fast and simple. Just touch what you want...it appears on the screen...simple as that! The factory choices of screen combinations is all most fisherman will want or need, but...for those needing more...yo can even set up your own split screen combinations making this unit the only graph unit you will ever need for any situation you may face on the water.

Rated 4 out of 5 by from Have had this unit for approx 3 months. Instruction manual very little use in helping getting started or even understanding how to set up. There are some pretty good You Tube videos available that are quite informative.

Rated 5 out of 5 by from Awesome product for the price! I recently upgraded from the Gen 2 Touch units to the Gen3, and for nearly the same price I get the benefits of Sonar Hub, a faster processor, twice as fast GPS update rate, multi-touch screen, and the list goes on and on! Glad to have all this and keeping the price of the product affordable.

Rated 4 out of 5 by from Good product I've benn owning this HDS 12 and really like the package. We offshore fish in the Gulf of Mexico and really like the contour lines that show the deep drop hideaways.

Rated 5 out of 5 by from HDS-12...A Clearer View Just wanted to say how much I like the new display of the HDS 12 Gen3. The non-glare feature is far superior to other units I've used and the expanded, simple-to-understand menu and display options make it quick and easy for even then most "technologically challenged" folks to use.

Rated 5 out of 5 by from Improved user interface Had HDS-12 Gen 3 unit installed at front helm of new boat. Have HDS-8Gen 2 non touch unit at rear steering station. Gen 3 unit is much easier to operate. Menus are easier to find and understand. Sonar function failed on 6th trip, but was replaced by store with new unit from box. Hoping failure was a fluke because I really like the unit.

Rated 3 out of 5 by from Ok Nothing special, just a few added features separate this from G2T. I feel the processor speed is about the same.
