These have been on our boat since new, and are currently running version Lighthouse version 15.61. Both work flawlessly.
The e127 has a built-in 600W sounder. Both units have a 50 channel GPS antenna built in, and will come with the latest Lighthouse II charts for the Pacific Northwest (other charts are available).
The e127 is flush mounted at the lower station, and the e125 is bracket mounted on the flybridge. Both will come with new power/video cables; I can supply a bracket mount for the 127 if needed.
Both units are still mounted- if you're in the Seattle area, pm me and drop by for a demo. I work from the boat, so I'm always available.
I'm asking $1975 for the e125, and $2175 for the e127.
