Lowrance's HDS-5 / HDS-7 high-definition chartplotter systems make fish scared

If you reckoned high-def was confined to the living room and / or theater, you've got another thing comin', partner. Lowrance has just introduced two new GPS-Chartplotter and Fishfinder combination units, both of which are the first on the market to combine "high-definition chartplotter capabilities and Lowrance's Broadband Sounder functionality into a compact, easy-to-install system." Of course, you won't be able to really take advantage of the HD inclusions on the 480 x 480 (HDS-5) / 640 x 480 (HDS-7) displays, but maybe the definition of "high-definition" is different on the lake. Hmmph.
