"He said 1200kHz continuous wave (not CHIRP) they tested was only getting usable data out to 40-60ft ... "

Only time I ever have mine set past 40-60ft is when I'm scanning new water. When I'm fishing familiar water the unit is set on 50ft looking for fish. We will have to use 455 to find cover past 60, them use Mega for a closer look.

I'm very excited about finally having dedicated DI with SI without having to step up to the Onix.
