I don't know. It's new just come out this month, and supposed to be better.
Guess I'll be finding out soon. A buddy of mine who we regularly fish together has the Elite 5 DSI, so I guess we'll have to do a side by side comparison. We did it with his Elite 5 DSI, and my Elite 4, now it's time to see if there is any advantage in the Elite 7 CHIRP.
Here is a take from the Lowrance site
- Easier to identify and distinguish bait and game fish targets
- Better target identification at greater depths
- Mark fish clearly at faster boat speeds
Exclusive Lowrance Elite-7 CHIRP advantages:
- Multiple CHIRP ranges from a single transducer
- CHIRP sonar performance with a greater number of affordable transducers, including the Lowrance HDI Skimmer®
- View multiple CHIRP sonar settings on one display
- DownScan Imaging™ provides picture-like images of fish-holding structure beneath a boat.
- Selectable single-frequency sonar operation with award-winning Broadband Sounder™ performance.
- Highly accurate, built-in GPS antenna plus a detailed U.S. map featuring more than 3,000 lakes and rivers and coastal contours to 1,000 feet.
