I can't believe I just spent nearly $300 on a FishFinder, but....it comes with down imaging and GPS and all of this:
OK, I KNOW IT'S NOT COLOR!
Humminbird® 581i DI Combo Fishfinder with internal GPS Receiver (Transducer Included-See details below)
"UNBELIEVABLE CLOSEOUT PRICE --WHILE THEY LAST"
-- I paid 299.95 with free shipping and no sales tax. Just enter freeship at closeout.
-- I saw it here: http://www.crappie.com/crappie/memb...at-buy-humminbird-581i-di-combo-299-00-a.html
The 581i DI Combo features a brilliant 5" display (640Vx 320H) to reveal cover and structure detail below your boat. It also sports the fabulous, new Down Imaging® and DualBeam Plus™ Sonar with up to 2000 Watts, peak-to-peak (PTP) power output, GPS Chartplotter with built-in Humminbird® UniMap™ covering the continential U.S. coastline, inland lakes and rivers.
In addition, it includes an SD card slot for maps and saving successful waypoints, to keep for returning expeditions. Maximize your angling experience with the Humminbird® 581i DI Combo Fishfinder GPS system.
HUMMINBIRD® PROFESSIONAL GRADE SONAR TECHNOLOGY
Down Imaging® - Now you can see in detail, what is happening below your boat. Timber, brush, bridge pilings, rocks and any other structure will pop with stunning detail as you patrol the water. Check it out! You'll like what you see.
Features:
Down Imaging® - "snapshots" are created with high-frequency sound waves emitted in razor thin slices. Sonar returns from these waves create an instant "snapshot" of the view below the boat.
Narrow Mode - analyzes the returns to verify the position of the echoes and ensure Down Imaging® only shows you structure and activity beneath you, and not off to one side or the other.
Down Imaging® / 2d Sonar - This view provides a better understanding of what is going on below your boat. Quickly identify structure with Down Imaging®, while using 2D to locate and target fish. Combined, they help take the guesswork out of sonar fishfinding.
DualBeam Plus™ - is the best of both worlds. With selectable narrow and wide beams you can view the display for each beam individually, or meld them into one display. Combined, the two beams provide much greater detail and a wider coverage area.
Precision-narrow beam for high accuracy returns of fish, structure, and bottom profile
Coverage-wide beam provides greater coverage for fish and bait fish
Beam Display Options -View beams separately, side by side, or blended together for the most complete picture
SwitchFire™ - When you hit the water, you don't limit yourself to one type of bait, so why limit your sonar? Exclusive SwitchFire™ Sonar gives you the power to choose how returns are displayed. With two unique modes, you have complete control to adjust with fishing conditions, making our down-looking sonar an even more valuable tool.
Features:
Max Mode - Incredible detail. Watch as the sonar returns explode from the screen in amazing detail. You’ll see the tiniest subsurface object—even thermoclines and water currents - for complete underwater coverage.
Clear Mode - Easy viewing in rough water. Time Variable Gain (TVG) software sifts through sonar returns to display only fish and structure. Great for shallow and rough water, or reducing undesired clutter in the water column
