I was extremely happy when those Elite-7 units came out. It created a less than $1,000 option for a mid/large screen head unit the value-minded angler could afford. It has almost everything most get in much more expensive units. Before the Elite-7s were introduced Lowrance did not have an option for a guy to buy a unit with broadband sonar, NMEA 2000 networking in a standalone unit that used the same blue connectors as the LCX, LMS, and HDS color screen units. So with the blue connectors if youre replacing or moving one of the previously mentioned units, you wont have to change any cabling, just add the HDI transducer. The Elite-7 can share waypoints with another Elite-7 or more expensive HDS units, and has the same exact sonar (broadband) as the HDS units, with a built in antenna, all for around $700. The screen resolution and detail is amazing, I absolutely love these units.
