Difference in series.

Ok ,I ended up buying a refurbished E127 because of the price point, warranty, water I am on and what functions I will be using 99% of the time. Interfacing it with new HD418RD and EV 200 ,engines not new enough to use the engine gauges feature. Lake Ontario has no structure to speak of so the digital sonar will be fine, as we fish thermoclines. Probably upgrade in a few years as newer models are always on the horizon. Thanks for the reply.
