Humminbird 587ci HD DI Review

Humminbird 587ci HD DI has an average rating of 3.67 out of 5 based on 3 user reviews.


The Humminbird 587ci HD DI is a combination GPS and fishfinder that includes Humminbird’s trademark Switchfire and Dual Beam Plus sonar technologies as well as their Down-Imaging system all displayed on a high definition 256 color 4.5 inch 640×480 resolution screen that has brightness levels that can be adjusted to read clearly even under direct sunlight. Switchfire brings to the user two modes of sonar viewing. The first is a maximum mode that brings incredible detail of the world below to the screen. Not only the expected cover and bottom, but also water current as well as thermoclines. The second is a clear mode which is for those times when the water is shallow, murky, or filed with sediment. These are times when getting every detail simply fills the screen. Clear mode filters out the unnecessary noise and gives you a clear picture under these challenging situations. Switchfire technology gives the user a detail option under conditions that make other sonars useless. Dual Beam technology sends a 20 degree 200 kHz and a 60 degree 83kHz sonar beam under the boat. The wider beam covers an area that is as wide as the depth of the first beam. These beams can be viewed side by side or in a combination mode thus giving the user a picture of the bottom as well as the surrounding area allowing the sonar to pick up all fish in the immediate area.

Down imaging is added to the feature packed Humminbird 587ci HD DI. Down Imaging is a sonar system that focuses thin slices of sonar waves below the boat in order to produce a detailed image of not only the surface but all cover, structures, and details of the area below.

In addition to these features the Humminbird 587ci HD DI also has an internal GPS system that can track 3,000 waypoints, 50 routes, and 50 channels and includes chart plotting, built in Uni-Map cartography, and an SD card slot for saving additional maps like Navionics and LakeMaster as well as additional waypoints and routes.

The unit is mounted on the included tilt and swivel quick disconnect mount has 2400 W peak to peak power and drop in replacement capability. This is an all in one unit that is affordable, versatile, and a solid budget minded choice.

I was able to buy this model before they discontinued it. I was looking for a smaller unit with Down Imaging, 597 was too big for my boat and my budget. It took only about 1 hour to install but then I spent several hours figuring out all the menus. I have everything setup now and it works great. The background maps don’t have lakes that I frequent so I had purchase a Navionics card but that’s the only downside to this awesome fishfinder.

This fishfinder is smaller than HB 597, only 4inch screen. But that means you can fit it easier on your dashboard. I bought it for ocean fishing even though Humminbird specializes in freshwater electronics. The sonar works just fine, it stays on the bottom. I used a Novionics card for the GPS and that allows me to navigate through a shallow bay. Overall, I’m pleased with the purchase.

I bought a navionics card for my humminbird 587 ci HD DI, but it will start laying out the contour lines on my unit and then it just shuts off and says loading on the screen. I cannot get it to load up the contour lines, roadbeds, etc. for the lake. Could it be that I am not in a part of the lake with good reception? I have been on Toledo Bend on the south end twice and it will not load up like it is supposed to do. It shows the bouy markers, which it loaded from my house over 60 miles away, but will not load up the good stuff. Any help would be great for me to get this information loaded on my unit.

The product itself? well… the product I think is ok… but customer service? terrible
I only used this unit for 35hrs before it crashed after uploading an update… yup… black screen with green letters.. “Matrix System version 4.300″… couldn’t turn it off without disconnecting power and it just rebooted to the same black screen
Humminbird said I would have to send it to their repair depot…. I expressed my displeasure with the whole situation of uploading THEIR RECOMMENDED UPDATE and it crashed my unit… they said they would contact the repair depot
So…$55 to ship…. $35 minimum service charge (obviously it was a very easy fix cause it took less than 2 hrs from time of delivery to time or email saying it was fixed) AND THEN THEY CHARGED ME TO SHIP IT BACK TO ME?
So naturally I contacted Humminbird and was told there was nothing they could do about it as it was already paid for and “I HAD AGREED TO PAY FOR IT” so what happened to them contacting the repair depot? Obviously that didn’t happen

And to add insult to injury?
After being firm… but polite to Humminbird customer care…. AND apologizing for any negative publicity they may receive due to this issue… their response?

“It was a pleasure working with you today. Have a great day!”
After 30+ years of owning humminbird do yourself a favour… buy a Lowrance or a Raymarine….
