Opinions on twinscope sonar please

[Jumping Cholla Jigs]

These are supposed to be a great tool for finding the larger schools of fish in the right feeding depths. Does anyone have one and what are you opinions? The refurb'd ones are not to much $'s if they work like they say they do.

Seems like I remember Cabela's carrying those for one season or so,
don't remember if it was the main catalog, or the salmon/trout or offshore
specialty books, I get so many different ones from them, hard to keep up.
It looks interesting, but I'd be kinda curious to see one in action before
buying - I'm watching the new side-scan from Humminbird close to see how
it pans out too.

I've used the sidescan and its pretty good for looking out beside the boat but hard to find schooling fish in pre-spawn and does nothing for whats in front of you. I guess I'll be the first one to give a report on the twinscope as Fedex is bringing one by this morning for me. One thing to consider right now if you are even considering one is the sale they are running on reconditioned ones. Under half price and still the full 5 year warranty. $699 for a $1700 forward scanning graph is not bad.
