Lowrance Structure Scan HD / HB Mega / 800 kHz

[sonarbear]

Since some of you guys have already picked up Mega imaging units, I was wondering, how they compare to the Lowrance HD Structure scan with the long LSS-2 transducer. This transducer has almost twice the length of the HB HD ducer, hence twice the resolution. Mega imaging has about 50% higher frequency, hence 1,5 times resolution. Under real world conditions, both should perform similarly well with HB having the edge at closer distances and Lowrance longer distance.
Does anybody have some data to compare? Or maybe at least a continous recording that shows the switch between regular 800 kHz and mega mode on a HB unit?

Thanks!
