Portable Fishfinder-NORCROSS

[ICEBUG]

I haven't found any talk about the NORCROSS FF 3300 model hand held finders.Anyone have any experience with these?I'm thinking of getting one for ice fishing and to use in the summer on my float tube.Otherwise, I would opt for the FL-8.Thanks.

Here is the only other thread besides yours about those:

They look interesting. I would have to see one in use before commiting to one. Looks like a nice option for use on a tube or a canoe or back country trip.
