Default Deep Water Sounder/GPS

I am after some advice on a GPS/Sounder unit for deep water fishing. The depths we fish is around the 200-600m(600-1800ft) for bass groper, blue eye and bar cod in Australia.

I've had raymarine products(c120 w 1kw) in the past, and was impressed at their deep water reading ability at speed(20kts). However was seeing if there is anything cheaper or better on the market.

I would like to have 2 x combo units with 1x 1kw transducer and another transducer as spare. This would enable me to run one unit as a stand alone Sounder with 1kw transducer and the other unit I would run as a GPS. But if either stopped functioning I can still fish.
Was considering Garmin( good price, not sure if it will do the job), Furuno( very pricey) Simrad( not heard alot about them), Hummingbird(again not sure), is there any I am missing?

I'm trying to stay away from a seperate GPS and seperate Sounder if possible.

So my criteria is as follows:

2 x GPS/Sounder Combo- sounder to work at 20kts reading the bottom and fish in 400m.
Not send me broke buying them. So total package under $5000.
Any advice would be greatly appreciated.

The 2 screens alone are going to be close to $5000. At those depths I would go CHIRP. Garmin GSD26 is a very good CHIRP. Simrad BSM2 is also good, but suffered a lot of bad press due to a year or more of bad firmware. Raymarine has a CHIRP, but I haven't heard much feedback on it.

Garmin has discounted all of their old lines 7xxx, 6xxx, 5xxx, and 4xxx due to the release of their 8xxx line.

Garmin 6xxx and 7xxx are not discontinued, it will be Garmin's new bread and butter on the marine side. The 6xxx and 7xxx prices are substantially reduced after the 8xxx introduction.

At those depths, CHIRP is the way to go, no question.

Better? Yes. Cheaper? No way.


I would like to have 2 x combo units with 1x 1kw transducer and another transducer as spare. This would enable me to run one unit as a stand alone Sounder with 1kw transducer and the other unit I would run as a GPS. But if either stopped functioning I can still fish.
Having multiple MFD displays is a good idea for many more reasons than just "reliability-through-redundancy". But unless you are really expecting the transducer itself to fail (which they don't, usually, at least not until they have several years on them), there's little point in buying and installing a second (expen$ive) transducer, which would be just as exposed to the same transducer-killing elements (most notably salt water) that puts the first one at risk.


Was considering Garmin( good price, not sure if it will do the job), Furuno( very pricey) Simrad( not heard alot about them), Hummingbird(again not sure), is there any I am missing?
As stiletto mentioned, Raymarine also makes a CHIRP-based sounder module (the CP450C). But between them, Garmin and Simrad, they'd be third on my list of preferences. Furuno has just last week FINALLY entered the CHIRP-sounder market; but they did so in a very minimal (and frankly, disappointing) way, not really suitable for your purposes. Humminbird isn't even in the game.

Both possible and easy.


So my criteria is as follows:

2 x GPS/Sounder Combo- sounder to work at 20kts reading the bottom and fish in 400m.
Marking fish (or even bottom) "at speed" is more a matter of transducer choice and (particularly) transducer installation, than it is a matter of the sounder module itself.


Not send me broke buying them. So total package under $5000.
Not going to happen, if you want top-quality stuff.

If you stick to relatively small (8-inches or so) displays, you might get away for US$8,000-10,000, plus installation. With twin 12-inch (or larger) screens, you can add at least another US$2K or so, probably more.

Well, not ALL of them. But 6000- and 7000-series are now mostly within reach of mere mortals.

I said discounted, not discontinued. If they had been this price when I purchased the Garmin/Simrad choice would have been tougher!

To be frank, I'm yet to see a reliable and effective chirp system on the West Coast of Australia.

Chirp will no doubt one day be better, but not personally convinced it is here yet. Not sure if its just the price, or lack of dealer knowledge, or flaky chirp firmware.

A very good setup, and as cheap as you would want to go is this;
FCV 585 (or newer 587)
MB100 junction box
200B8B transducer
50B9 transducer

We have had it sounding out to 832m and routinely catch blue eye around your target depths.

That is odd that CHIRP works worse in Austrailia. Maybe it's the Southern Hemisphere and the reversed toilets?

Well, it isn't just Australia. I've been both posting amd reading about chirp since it was announced and this board is littered with people having problems with various Simrad firmwares. At least one of the dealers selling Simrad has replaced a few installs with Furuno sounders.

I would say that if you want reliability and knowing that it will just work, then the conventional Furuno setup is a better idea. As a side note, I would give you nothing for a lowrance conventional setup, but don't mind the Raymarine gear.

If you don't mind bleeding edge gear, and bleeding, then maybe go with one of the chirp offerings.

I'm going to be in the market myself soon, not really sure if I will go chirp myself yet either.

Garmin CHIRP has always had good reports. They got it right the first time. Simrad has done well for about 6 months now since their 1.5 firmware release. Guess it is hard to overcome a year or more of insufficient firmware releases.

Locally there have been poor garmin installs and even worse garmin support, maybe they care more in the US.

Oh and for the OP, Furuno and Raymarine have a A-scope and good bottom lock, both of which I have found essential for finding fish in deep water.

With the FCV 585 we tend to use bottom shift to show the last 100-150m only, run A-scope and bottom lock as well.

Not sure that is correct about effective chirp sounder working well on the west coast of oz. i have recently replaced my 2 furuno 10'-4s nav nets with 2;nss12 with bsm2 chirp works really well.still playing around with all the wonderfully features To me chirp is the. Way to go if you can. Afford it. Or. Your. Fishing requires or will benefit from it

I think with the demoed results from the Dragonfly, there is no denying that its good for shallow water, I'm sure it will change deep as well.

If you're getting good results, why not put up some posts on fishwrecked.com?

What about the new Garmin 7xxXS with a 1kw transducer [chirp] Know its due out very soon..Does anyone know anything or will they do that job. Aussy could use 2 of these-- using 1 as GPS and the other as a sounder[if it will do that depth]That way he has back up should either unit fail. If the sounder fails he only needs to plug transducer into the other unit ?Should be close to his budget given the prices of the current model although I realize the new model will be a bit ??? more expensive
What are opinions on this please???

I don't believe the Dargonfly will be suitable at 1800ft, and I think the Garmin 741xs will also be hard pressed at those depths. I would go full CHIRP with either the GSD26 or BSM2.

Simrad has been very good since going back to the older firmware.
I've heard rumors from a very reliable source that April will be the release of the new firmware and I hear that it's going to be be big.
I'm on the Pro Staff Team so I'm sure my source is good.

Ive had very reliable experience with the Simrad BSM2 since the 1.5 firmware was released. I run a B265 through hull with high speed fairing and manage to track bottom in any depth at even high speeds 20kn+. Bottom discrimination is also excellent now, which i find useful given all the deep drop fishing we do here on the East Coast of Australia.

Interesting news Jeff about the firmware update.
