What's ur opinion on omni? Was I way off base with chirp is a simplified version of a tunable sounder?

The Furuno CSH5LB/55 Omni system is fantastic for targeting specific species such as herring, Mackerel, anchovy. etc.

OMNI is the system of choice for trawlers and seiners .

I have used a MAQ omni on a friends boat...and have wanted to use the Furuno.

Correct me if I wrong.
The selection of the frequency in tunable sonar is done by the user.
CHIRP is using all the range of frequencies of the transducer and with a clever algorithm and a lot of filtering it produces images of what it is seen by the sonar. So CHIRP is combining information from the whole range of the transducer rather and produces resulting image...

If this is the case then how can someone say that CHIRP is more clever than manually selecting and observing just a single frequency from the range?

Also does anyone know if existing Furuno 585 can utilize the 265 even partially in a tunable sonar manner? If yes have you seen any results anywhere?

More news from Furuno!
http://www.furunousaforum.com/viewto...=7&t=235&p=991

"We will introduce a new stand-alone CHIRP Sounder in the summer of this year and then introduce a BB model for the NavNet toward the end of 2012."

I agree with u its a dumb dumbs version of a tunable sonar for people who can't or don't want to understand how to use a sounder.

Maybe semper can jump in here and clarify. There is obviously a number of people who believe these CHIRP systems are for the blokes who have no idea how to use a sounder correctly and/or tune one manually! Do you believe this to be the case?

I don't think semper can say its a dumb dumb technology considering he sells it. Its a good system that simplifies the technology.

That may be the case but he may be able to clarify this. I am of the belief that this is not just a simplified technology. It has been used for many years just not a small enough system for recreational use until now. Also instead on being able to tune into 1 or 2 frequencies, it is able to scan a number of frequencies at once. Giving less noise, greater depth penetration, target seperation, sensitivity and covering the whole water column. Instead of just being able to target a single species at a certain depth. You will be able to find different species at different depths better. The system also allows you to tune into a single frequency just like any other tunable sounder.

Not many times I'm deep dropping in 1600 feet and wonder what's at 200.

I think some of you guys may be missing the boat on chirp. Its not just sampling at one frequency but multiple frequencies and the processor is sorting out fish from everything else. I understand chirp can will identify a fish holding 6" of the bottom in a 1000' of water. thats pretty damned impressive.

Thats good news about Furunos CHIRP unit this summer. I'll be interested to see a side by side comparison with the GSD 26. I'll also be interested in how Furuno prices their units since Garmin beat them to market.

And another quote from Furuno on CHIRP:

http://www.furunousaforum.com/viewto...lit=chirp#p939

"CHIRP would require new hardware so don't look for any software updates to provide CHIRP in the DFF3. It has taken CHIRP to get others even close to what Furuno has been doing for years. When we add the feature, you can be darn sure it will be worth having. "

you should. plenty of stuff like marlinetunawahoo will check out your boat while its floating there.

only within a few feet of the centre of the cone .


if furuno bring out a standalone chirp sounder it will reinforce their standing as a company that makes fishfinderrs for fisherman and are more than just a marketing company. this whole black box chirp you need our MFD as well more money is too much marketman for me. plus i need a whole screen and all the buttons on it dedicated to a sounder.


chirp works by sending a pulse with a variety of frequencies. and then looking for that same pattern on the return . enabling it to reject everything that isnt that pattern. so it can potentially give you more than any single frequency system tunable or not. because it can use the low frequency end of the pulse to identify real echoes but only display the highest frequency data, and as that pulse length of each frequency subset of the main pulse is shorter than a tone burst system you can theoretically get amazing detail . better than 200hz detail at 50 hz depths.


i am still waiting to see convincing screen shots from chirp in rough weather.

Not gonna deal with shallow water stuff when daytiming with 2000 feet of line out.

its not just shallow water stuff. would you change your fishing approach if you were marking sword fish in 1500 ft when you were dropping in 1900 ft?

Its not that it makes someone smart or dumb. In simpler terms it takes the guess work out of a tunable sounder and still allows u to determine frequencies. I like the idea and think for rec use its a much better solution than a tunable sounder.

Furuno has had tunable sounders for quite a while, certainly before anybody started talking about CHIRP. Yes, geared toward commercial guys or people with solid knowledge of the best frequencies for what they are targeting or situation their in. CHIRP just scans all frequencies automatically for you. It is not better technology or a better sounder just more user friendly; which is the case with furuno stuff as a whole. Furuno has stood the test of time around the world in every ocean and on most commercial and working vessels you see for a reason; performance and reliabilty. I won't buy anything else, however I have been very impressed with the simrad line.

No, I am not of that opinion.
CHIRP is an improved and advanced system in total.

Anyone currently using a traditional system is wise to stay with that system if it fits their style and needs.
Anyone who is undergoing a total re-fit or a new build should at least consider learning about CHIRP systems.
That is what my goal here on THT..to help provide technical information concerning all sonar systems.
Including CHIRP.
In that way one can make a choice based upon technical information rather than advertising hype.
An informed choice.

This is a superior system compared to a traditional tone pulse sonar.
If not so..why has every manufacture spent the last several years in costly development....just to give everyone something "user friendly" ?
No, this is a better system.
And it is a system..both CHIRP sonar and CHIRP transducer.

Lets just begin with CHIRP transducers. (I will cover the Sonar itself later)

All sonars are only as good as their transducers.
Traditional tone pulse sonars are still limited by high power requirement to gain depth , signal to noise ratio and transducer quality.

CHIRP uses only a fraction of the power required by traditional tone pulse units...but transmits more energy into the water.
Increased energy onto the target means greater return echo energy which leads to improved target resolution.
Add a superbly sensitive CHIRP transducer.....the gain in target separation and resolution is impressive.

CHIRP transducers have higher quality ratings... a Q of 3 and less .
The lower the Q the less ringing.

The increase in round trip sensitivity of a CHIRP transducer over a traditional transducer is pronounced.
I have customers who are blown away with the improvement from a B60 to a B260...that is an increase of 250 times round trip sensitivity on the low band and 50 times on the high side.
The CHIRP B265 is 1000 times more sensitive on the low side than the B60...120 times on the high side.
The CHIRP B265 is 750 times more sensitive than the B260 on the low side and 70 times more sensitive on the high side.

The CHIRP B265 is the same size as the B260 but 750 times more sensitive.
Twice as good and the same physical size would be bragging rights.

But 750 times better........thats impressive.


You cannot debate just CHIRP sounder technology vs traditional sounders.
One must also include comparison of CHIRP transducers. vs traditional transducers.
Its a total system.
