The picture-like images of Humminbird® Down Imaging™ are created with high frequency sound waves emitted in razor-thin slices. The sonar returns from these waves create an instant ''snapshot'' directly below your boat. Our exclusive software analyzes the returns to verify the position of the echoes to ensure Down Imaging only shows you structure and activity directly beneath you, and not off to one side or the other.

Performance fishfinder offers 4000 watts PTP power output and reliable depth to 350' (DI)/600'. Sonar coverage: 25º and 16º. Speed/Temp: Included. LakeMaster™ and Navionics™ compatible. In-dash mount: 5.4''H x 6.9''W.

Rated 3 out of 5 by ChiefDrop Good depth finder; mediocre GPS
As expected, the GPS isn't as good as my old Garmin 176. I bought the unit expecting this but was willing to give up better GPS capability for better depth finding. I like to track my total distance traveled per trip but this doesn't seem possible as the GPS records a speed when you are stationary. This, in itself, is not a big issue however, the unit seems to use this bogus speed in its distance calculations rendering the trip log feature useless. I guess I will have to take my little Garmin eTrex with me to calculate my total distance.

Rated 1 out of 5 by alabamanana4 right purchase?
Bass Pro Shops was great. I got the unit in a timely manner........an't say the same for Hummingbird. I've had the unit for about three weeks. It is still not on the boat. The only transducer option was a transom mount, so I contacted Hummingbird for an exchange and they said "no problem". I was told that it would be shipped the same day they received the transom mount. When I responded back, after not receiving the unit for several days. I was told that it was on back order. Nothing was mentioned about this earlier. I can't believe that Hummingbird did not have a trolling motor transducer in stock, in the month of April, peak of the fishing season. I wonder if the person in charge of their purchasing has ever fished!

just bought this depth finder hoping it will put me and the misses on more crappie. only used once so far so still figuring it out. however has amazing screen clarity in any light situation. shows good bottom detail with the down imagining. i will recommend but if ur not one of the pros be ready to just have a few trips on the water to figure it all out!

I had an external antenna set up with my 318 and the quick disconnect connections are the same on the 597 . I hear that you can program the unit to use the internal or external antenna. I haven't looked at that and am not sure if mine is using the internal or external antenna, since both are hooked up or installed
I had no problem installing it. Took me about an hour at most. Installed the transducer and ran the wire to under the dash. Mounted the quick disconnect and connected the power wires to battery and ground. Connected the head to the quick disconnect and it worked just fine.
