More Details

I'm a long time Garmin device owner. I absolutely like the quality and support after purchase for all of there products. upgraded to the Ecomap Ultra 2 166sv recently. I already have Ecomap Ultra 126sv. The new chartplotter allows me to take advantage of some new features only available on the new chartplotter with the new Spy Pole, Force Pro Trolling motor, and the new Livescope 2 transducer. The bigger screen allows me to see more detail.

Great unit

Love my 16. Have it flush mounted at the helm console. I prefer it over a dual graph mount especially for visibility on plane. Its large size easily accommodates a split or multi view configuration. The true HD screen has amazing detail.
