Default Humminbird Sidescan fish finders

Anyone have any personal experience with one?

I emailed humminbird with a couple of questions and no reply. So much for customer service.

Please - only if you have personal experience.

Do they work as advertised? How fast can you cruise and have the sidescan feature still work well?

Thanks

I use the Matrix 97 side scan out in the ocean when I'm Ling cod fishing around Seal Rock. And the side scan at 10 mph shows fish. The slower speeds give a greater detail and shows a lot more fish.

When I'm Salmon fishing. I scan while running 20 kts. When I find a school of fish off of the port or starboard side,I can circle wide enough to lower the gear and start trolling.

So far I am very happy with my unit.

Inspector62,

I asked the same ? on a different forum. If you happen to get any feed back from elsewhere, please post it. I too am thinking of getting the side scan sonar. if it does what it shows it should be awsome to find structure and fish.

Thanks,
Joe

I don’t frequent this site and was asked by a member to respond to this message.

You are asking about the Side Imaging (Si) sonar on the Humminbird 981c Si, 987c Si and this year’s 797c2 Si and 997c Si models. Our Customer Resource folks may be a bit behind on answering e-mail so I would direct you to a Yahoo group web site:

http://groups.yahoo.com/group/sideimaging/

You should be able to find answers to most of your Si questions from fellow fishermen. There is also a growing photo album section with many screen snapshots from 981c Si, 987c Si and the new 797c2 Si units from users who have imaged structures and fish on their units.

How fast the Si sonar will work at different speeds will all depend on your boat, how the transducer is mounted and what you are wanting to get out of the Si sonar. If you only want to know the general shape of the bottom under the boat; I have been able to do so at 40 mph. If you want to see a detailed image of the bottom, you’ll have to slow to 3 to 6 mph.

I have a 987c. I am mostly happy with it, although others love it.

If I were a flats / lake fisherman or were usually in < 30 feet of water, I would say it is amazing - as I go under bridges I can count the pilings.

In the ocean I find the side scan features to be useful to 60-70 feet at best. That's still pretty impressive.

I think greg is being a little optimistic about speed though. On flat water the unit will produce an excellent picture of the bottom between 3-5 mph. Past that it gets a little iffy. The transducer is pretty large - and mine may not be mounted so well - but I find that I lose bottom at any sort of cruising speed and often have to stop and wait for the finder to get a lock. I would say on a good day I will get a choppy image up to 10 mph.

ALTHOUGH - like I said many people absolutely swear by them. It is pretty neat tech compared to a regular fishfinder, and the whole package (gps etc) isn't bad at all for the money. And despite me sounding negative, I would probably buy another one if it came down to it.

PS: I have had very good luck getting responses from humminbird both via phone and email. Definitely a thumbs up for customer service.

How deep will the side sonar go with a good picture? I just bought a simrad cx-33, I am about to return it and purchase a 997c si. Looking for some feed back, I fish in about80 -160 feet of water. Will this unti work for me?

The Humminbird 997 has not been released yet.Yes it a good fit for your depths.The 997 has some significant changes over the 987 that have been in use over the past 2 years. Here is a non listed link to the Humminbird web site that will get you into the New Units Web pages; " http://www.humminbird.com/products.asp?id=964 "

I hope to have one availiable to show at the New England Saltwater Fishing Show;" http://www.nesaltwatershow.com/ "

Adam you’re right; I was a little too optimistic as the fastest I was able to capture a readable image was at 35 mph. This was on our test boat (ZX20 Bay) which was amazing considering the number of other transducers we have hanging off the back of the boat. The screen snapshots of this and one at a slower speed to compare the amount of detail you will miss at faster speeds is available in “Other Interesting Images” album in the photo section of the Yahoo Side Imaging site.

http://groups.yahoo.com/group/sideimaging/

While there you can look in the Images: Deep Water album for the Si screen snapshot captured at 182 feet of water.

Greg,
I was in Eufala last Thursday with Bart Boyd and David Taylor. Prior to my visit I had mentioned to Bart that I was about to buy a Scout 205 Sportfish. He arranged a demo ride for me on your test boat.

Very impressed with 997. Saving a spot on my console for one.

Default RE: Humminbird Sidescan fish finders

I have one of the 987C's and have had problems with getting accurate readings. It intermitanly goes from 2' to 80' when I am offshore. We went to the floaters last fall and once i got over 250' of water it would not read at all. I spoke to a gentleman at the boat show and told me to take the transom mounted transducer and epoxy it in the bottom of the hull and my problems would go away. Any body know who I can contact for assistance? Currently I am depating about gettting one of the Furuno 585's to replace it with.

i have the same problem when i am at speed it will read a crazy depths.. i can be in 18 ft of water and it will read 2500ft. ive been in contact with the tech guys at hummingbird and they told me to lower my max depth to what i expect to be fishing in. soon as i get a break in the weather i will take the boat out

That does NOT sound like a good idea for the side scan transducer... for a regular straight down transducer, sure. But I would imagine that the side scan would be a bit more sensitive to that kind of mounting.

Mine usually reads 2500-3000 ft when I am at speed. If I slow to idle and let it get a grip on reality it'll start giving me good readings again. The transducer is just so big I think it's tough to get it mounted properly and in clean water.

I have not ordered mine yet but have heard that you will have better luck getting a transducer switch a dual beam transducer for high speed. They also have a in-hull ducer (plastic) that will give better higher speed side imaging and higher speed 2D too.

From what I understand, a lot of the pros are doing the two ducer install to get high speed readings and also to protect the $$ SI ducer.

Keep in mine that the in-hull ducer is a 50/200kHz ducer not 83/200kHz frequency.

Is there a through hull for side imaging units? My single inboard just says "no" to transom mount transducers.

Yep, there is a thru-hull SI ducer but I believe it to be plastic.

Let me see if i can shed some light on some of the questions asked here about the Side Imaging Humminbird units.

Humminbird produces now a affordable line of side imaging sonar with GPS that work in both freshwater and salt,including offshore.

These units are misunderstood by a lot of people,but are not hard to learn how to opperate with all their built in features.

In the northeast they have not been highly requarded as some of the name brands. "HB,there just a freshwater bass fisherman machine".. That's about to change,as a fisherman i like to keep my advantages close and not widely know to other fishermen.But this technology HB has out there now can be used by alot to improve your fishing results.And i don't feel i should keep it to myself for alot of reasons-so here goes.......

The key to their(Humminbirds) Side Imaging sonar is their tranducer,that they make in house.It contains both the normal downlooking sonar elements along with the side imaging elements. It does the normal downlooking sonar beams at 2 fequencies of 200Khz(with a 20*cone angle)and a 83Khz(60*cone angle)with the normal displays-real time and the normal graphs.The 83Khz,1000 watt(rms) is good for 1500' depths down looking.

Now the Side Image(SI) elements in the transducer are 455Khz(2-86* cones of vary narrow width) and 800Khz(2-72*cones of vary narrow width) that cover app. 90* off each side of the boat, App 180*across the beam of the trasum,from the bottom to all most the surface across the backon both sides of the boat in a very narrow beam width.The display can show the the downward beams only,both SI side beams ,only the left or right SI beam,or a combined downward and one on the SI sides. The SI works to 150-200' depths inshore.

We all know structure is the key to fishing. The HB SI machines allow you to find structure very easy inshore ,and therefore the required bait for offshore fishing.

What the machine does is when you find the structure,it allows you to start recording it to a SD(Secure Digtal)card in the unit-for review.Now here is the key- it records so when you review the data,you can place a cursor anyplace on the screen and it makes it a way point,you can then return to over that exact spot-nice trick hey!!!

As any sonar transducer, it is best to place it in a clean bubble free waterflow zone off the transum,it's even more important with this complex SI transducer,but it also needs a clear view to each side for the SI function. Humminbird is going to make a bronze SI thur hull for the 997 unit ,but it's not availiable right now.They have only recently started shipping the units out(2 weeks ago).

Hopefully i have cleared up some of discustion here. Is more info needed ?

That's how we did mine last year. I just received the 997 last weekend and will have it installed next week. In this year's boat, I had the factory install the thru-hull as the boat was being built and will have an A/B switch on the console to toggle between the transom mounted side imaging transducer. The thru-hull works great at high speed, I have screen shots from last year where we were running at 60 and reading bottom fine.
