Elite 4 DSI or the Elite 5 DSI

[blitzburgh]

Two key points:

Elite 5 DSI: Output Power [kW] Max Peak-To-Peak 4,000 W / RMS 500 W
Sonar Max Depth 250 ft \ 76 m

Elite 4 DSI: Output Power [kW] Max 2800W PTP, 350W RMS W
Sonar Max Depth Max 200 ft \ 61 m

Also, BIG difference in screen size. If the money isn't the issue, the 5 is the way to go IMO.
