    The days of a pixilated "fish-like objects" on your fishfinder screen are quickly becoming a thing of the past.


    They say that when you need the absolute best, to accept no substitutions. In the case of the Humminbird 987c SI Fishfinder Combo, you would be hard-pressed to find anything that comes close to it.



    The days of a pixilated "fish-like objects" on your fishfinder screen are quickly becoming a thing of the past with the advent of high-resolution screens and Humminbird's award-winning Side Imaging (SI) sonar technology.



    With a large 7-inch color display with 480x854 resolution, you will be able to clearly view what is below you, or find your way around the lake with its integrated 12-channel WAAS GPS receiver.


    Before we get into the specificsand technical data -- here is the 900 series in layman's terms: 1. large, viewable screen, 2. tons of power, 3. GPS receiver. And you get it with the Side Imaging Sonar which utilizes two very precise sonar beams directed to the sides to "illuminate" the bottom contour, structure and fish and display in a "picture-like" image. Side beams are extremely narrow front to back providing "thin slices" of the bottom for high resolution imaging.

    And now for the nitty-gritty:

    Built-in UniMap of the USA coastline, and inland lakes and rivers to 4nm detail
    Tidal graphs and port services information available with optional Navionics Gold Charts
    750 Watts RMS, 6000 Watts PtP (200kHz) power output, 2 1/2 target separation, 1000 ft depth or 1000 Watts RMS, 8000 Watts PtP (50KHz) power output, 2 1/2 target separation, 2500 ft depth
    Dual microprocessors and triple channel sonar transmitter/receiver deliver fast, smooth operation
    Full screen chartplotter, 3D bird's eye view chartplotter and split screen sonar/chart with adjustable split
    Programmable view presets access important screens with one touch
    Plug & Play compatibility with WeatherSense(r) Barometric Pressure, and Wireless Sonar Link Advanced Accessories
    In-dash or Gimbal mount.
    Additional Features:

    Fresh and saltwater set up options for optimal performance in any environment
    Water surface temperature included in transducer, GPS speed included
    PC Connection capability to save waypoints, and upgrade internal software
    Accelerated Real Time Sonar(tm) operates at up to 40 times per second to instantly capture the action under the boat
    X-press menus place most important setting at your fingertips
    Freeze Frame pauses the sonar scroll for detailed inspection of the screen
    Instant Image Update immediately shows the results of setting changes for the most accurate fine tuning
    Sonar Echo Enhancement(tm) technology is so sensitive it'll track a jig to over 40ft and separate targets within 2 1/2 inches.
    Fully-gasketed waterproof design & it floats
    Selectable large digit screen for easy-to-read number display
    Backlight for night viewing
    TripLog with distance, elapsed time, and average speed
    Totally automatic operation or totally manual operation with upper and lower range control
    Temperature graph overlay and audiable temperature alarm
    One-touch Zoom with 2x, 4x, 6x, and 8x zoom levels
    Adjustable chart speed
    Feature memory retains your settings

    For anyone that is thinking of this unit,Keep in mind. The Transducer on this unit is over 6" long and a little wider than most. There has been reports of the transducer making a small boat not run right on plane. As with that big of a transducer dragging in the water I would act like a trim tab on the back of the boat.

    If you have the unit set on Side image here is 2 settings for it. One is 455kHz provides highest resolution with 160° total beam width. So this one gives you the best picture on the screen. This one has a clear picture, But it angles from the boat to the bottom. So if your shooting out one side 120 ft draw a line from your boat out to 120ft and that is what you see.
    Then you have the 262kHz provides maximum coverage with 180° total beam width. The picture on it is not as clear. But covers the water column from the top of the water to the bottom all the way out to what you have the setting on. So if your shooting out one side, Say 90 ft. You are seeing everything between you can the 90 ft top to bottom. With this setting you can see the front edge of a dock or barge. Yes even see a barge. Or like this picture. http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake001.jpg The straight line is the front of the dock. And you can see the spud poles the dock sits on. And even bait fish and fish under it. This is on 262Khz if it were on the 455KHz you would not see the front of the dock.

    Any questions I can help with let me know. I in no way have learned all that this unit will do. but still learning every trip out.

    Here is a question I get a lot. How well will this unit work in shallow water.
    Here is a screen shot from Harrison Bay North of Chattanooga Tn. Took it With Whistler in the boat with me. So He can also prove this one.
    The side image shows a ditch and 2 different set of beds. Now what is using these bed i don't know. But just think what this could do for fishing.
    http://img.photobucket.com/albums/v693/ShilohRed/fishing/Harrisonbay008beds.jpg
    When the fish are on the beds. And they will use the same beds for years, So find them and fish them every year.
    The photo above is in 5.4 ft deep water, And the water temp was 71.3 the boat was moving 1.9 MPh. You can also have the picture show the way-point on it. Also that is scanning 64 ft out both sides of the boat. I could have made one more pass with only the right side scanning, And shooting out around 40ft and you could see every fish in the beds. Next time I will make sure I do that.

    First picture is of a school of catfish. Yes I caught fish out of it. http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/306pickwick003.jpg
    The mark on the school of fish, Is from the mark of a way point with the GPS. As I marked it, Then drove above the school of fish and was able to set up on them. Now is that easy or what. Sit the GPS part of the unit up on a trolling grid and you can get above them what ever you need to.

    This one is of a bait ball with fish around them. http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake006.jpg
    The bait fish are in 17 ft of water, and the water depth was 36 ft. Also you can see the steep bank. It drops straight off from 5ft to 25ft. And the log there also.
    Then this one is also a ball of bait fish. But the bait fish are swimming fast see how they angle and the fish are behind them. Not around the bait? http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake007redo.jpg Looks like there hungry..

    Ok who thinks they could have found this spot with there depth finder? And figured out it looked like this?
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake0010.jpg
    Left side of the shot. And the marker is on it where I marked the Way point.
    Nice hole right in the middle of the stuff and full of fish.
    Here is one of the depth finder showing the fish in the hole.
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake0020.jpg
    I have fished this place for years. And did know there was a few hangs there. But Had no ideal this stuff was there.
    So you can bet here will be some big hand size bream drifted through that hole soon.
    More on the way. Anyone have any request? Something they would like to see posted?

    How many times have you heard someone tell you. Man theres no way that is a tree on your depth finder?
    Yes I know its hard to believe for a lot of people. but if and If you had proof would you believe it?
    Now say your in 6ft of water, And dropping into 25ft. And the Tree is hanging off the drop. And you could see it on a side scan and the standard Depth finder.
    So you think that would make it where you would believe it?
    If so check this out.http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/sidescantree01.jpg
    Now this is on a point of a creek channel and the old river channel. Also has an old road bed that is under water running close to it.
    What do you think of this?

    Had a question on setting the side scan to shoot out the side. Say your in a place thats only 130ft wide. And you have have to run the channel in one side. Say 34 ft from the bank. That leaves 96 left.
    Just set the unit to 100 ft and shooting out both sides And in the picture I'm posting it shows what you will see on the right side.
    It does not bother it to over shoot the bank on one or both sides.
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/TnRivertreetopstepslast.jpg

    As you can see on the right side theres a steep bank or drop off. And along the top of that is dark space. The dark space is where its hitting the dry bank. so no reading of the bottom.
    Also you can see the trees laying there under water. All that was above water was a little stickup that looked like a twig.
    So in other words it does not matter if your over shooting the bank or not.
    Also until you get used to it unit. You can run the setting out on to where you see the bank and get an ideal on who far out the sides to shoot.

    People ask, Can the Humminbird 987c SI show arches. Yes they can, Will it look as good as the arches on a SO and So unit? Well that I can't say. ( DH can you add one from yours to compare?) But will post a few from mine.
    Also I'm still learning the unit.
    So with learning there getting there.
    Lots of bait fish and fish. Some arches small ones
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake002redo.jpg
    This one is from yesterday on the water.
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake005redo.jpg
    One of favorite fishing holes. And could not get this fish to bite.
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/pickwicklake004redo.jpg
    This is one other.

    Pete,
    Great pictures and sonar images. Do you still have the two we found at harrison bay of the ball of bait fish the size of a car, and of the rather large catfish hanging a few feet off the bottom. I can attest to the power of Petes unit and think it is truly a good investment. It has so much power and so many features that it is almost unreal.

    Here's a few shots of arches on the 987. There not as easy to get on this unit. but it will show them.
    Pete

    This one is showing fish and we caught 33 along this spot. And the bigest was the 45 lb 12 oz blue.
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/Octblues09036.jpg
    This one is of the turn up at the dam for the flood gates. The part that makes the water boil up when the water is hititng it. Also did it with the black background to show the difference between it and the white.
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/Octblues09032.jpg
    Here it is with the Zoom set on 2X
    http://img.photobucket.com/albums/v693/ShilohRed/Sidescan/Octblues09033.jpg
    Arch in deeper water.

    Here is a whole tree. The root-ball end is laying toward the top of the drop. And the top of the tree is laying at the foot or bottom of the hole.
    I have it showing in split screen. 2-D and side imaging.
    This give you a chance to see what you know is a tree on a unit and there is even 2 fish in the tree top.
    I was lucky and was able to after marking the tree, To run right back over it and spit it in half with the boat. Now how is that for marking a tree?

    hello,
    that is some great info. I'm interested in the UNI maps that are imbedded into the systems. I'll be fishing on the James river. How detailed are the maps? Do they have depth markers and wrecks on the maps? I was looking at the 787 version. thanks,
    Mcal
