Looking at the 2 units side by side, it doesn't look like that big of a difference. I guess it could be the scale of the pics.

While I admire the technology and think it'd be a great tool to have, if they keep going at this pace, they'll price themselves out of the market. Heck, these units are probably out of the question for most of us. I'd have a hard time thinking of any other technology item in the last several years that had a price bump like this.

Would be nice if someone (canepole) could use this technology and create the same unit to be used with a laptop or tablet. I'd think someone could cut the cost, and still make a bundle. Plus the processing power would be so much greater.

I'd feel pretty silly having bought two of these units on my boat and going home with no fish.....
