Humminbird 4084801 587Ci HD DI Combo DualBeam Fishfinder and GPS | Marine Electronics

I got this for my husband for our anniversary to go in our new boat. We both love this handy fish finder! It's accurate for speed and water temp and we can plot our favorite fishing hot spots and look them up with ease while in the boat. Hooking it up took no time at all once we decided exactly where we wanted to mount the transducer. Love the dual screen feature! Can't say enough good about this unit! So glad we got it! Once we got back home, we had recieved a catalogue from a local competitor and they had the monochrome version "on sale" for just about as much as we gave for our awsome unit plus paying for overnight shipping. Thankyou Amazon for giving us the best deal for our money!

Myself and my sons are completely happy with this product. It has great resolution and is quite easy to use. The inclosed Cd is extremely helpful.

I just hooked up my 587ci HD DI and couldn't be happier. I noticed a few reviews saying the down imaging is not as advertised, but I found it to look and function even better than advertised. The 4" screen is fine for me, but of course 5" would be nice (at least $100 more with 597ci HD DI). The split screen views are great. Installation was straight forward. I took my time and spent a couple of hours tying cables and getting everything just right. Only complaint I would have is that it seems to have no data on the lakes that I fish. I ordered the Navionics Hotmaps Premium 2012. This finder can only run Lake Master software, or Navionics: Gold, Hotmaps, or Hotmaps Premium. Premium means the software is the most up to date. It's too bad Humminbird discontinued this product. It was very hard for me to find at a reasonable price - since they replaced this unit with the 587ci HD (no down imaging).
