I played with it today and it crashed (i.e. could have been bad power feed)...lol... In addition to the touchscreen the unit has a twirly wheel/button that allows you to really zip through stuff quickly and I do not think cold weather operation should be a challenge.

I think we need to clarify whether the Lowrance stock transducers are compatible...apparently ss and sonic hub are compatible so I suspect the transducers should be as well.

I would seriously consider the unit if you can stomach the cost and frankly I thought it was the easiest, fastest and most intuitive machine I have ever used and Jack did not pay me to say that
