Wally13,

Thanks for sharing those reviews.  They're definitely helpful!

I'm thinking the 1X "gray scale" version will draw less power than their 1C "color model" (which was the one reviewed) and, therefore, do better than the reviews indicate on battery life.  Gray scale is all I'm looking for.  I like the compact nature of it, too. 

Hopefully someone out there knows someone who might have personal experience with the unit.

My brother is the one looking to buy one (for me).  He told me my Cuda 242 was "crappy" and took exception with its reliability when it showed some of the lakes we fished around Quetico with depths greater than 2500 feet.  Me?  I just drop the zero and figure that gets me close enough....

Thanks, again!
