Default adjusting digital sounders.

Can somebody please advise me how to adjust a Ray dx600, so i can see the fish marked like arches and not as stretched seaworms. I just can't find the right angle on the transducer, nor can i set up the machine to not lock on the downriggerweights. I have read a thread here once for a good setting for the Ray DX series. Just can't find it now.

Does anybody out there also have problems to set the speedreading correctly on the Ray DX? I have tried to to play with the 200% i have in the machine, but speedreading keeps going between 1-2 knots and shows far too much if i have runningspeed. I read somewhere that the Airmar transom mounted transducers with the paddlewheel in the back, could play around with the speed. You have any idea how to handle this?
You know if Furuno fcv 620 with transom mounted transducer has the same problem with speedreading?
Thanks in advance / Jussi

First off, take the paddle wheel off of your transducer, lay it down on a good solid peice of concrete, and smash it with as much force as possible with the largest sledge hammer you can find. Sweep up the peices, and drop in the garbage. Then, look at your GPS SOG(speed over grond) data box on you chartplotter to see your "speed". Now your speed problem is solved. The paddle wheels are uselsss.

As for the right settings on the DS600, everything in auto should work just fine, you should see your outrigger weights below the boat like a small plannet udner the boat!!! I see my little 1 ounce jigs bouncing off the bottom under my boat in auto mode. A 5 lb weight should light up bigtime.

How deep of water are you in?

Sounds like a good idea, getting rid of the unit because i'm fed up on the problems that just sems to be more!

I have had lowrance transducers with the paddlewheel and they have worked fine. speedreading has been accurate with them. airmar have that paddlewheel on the back and i just wonder if Furuno 620 has the same problem reading speed, on their transom mounted transducers?
If not then i can just get rid of the ray 600 because the problem is in the software.

I fish in 300 feet cold crystalclear water wintertime and i guess this can cause the machine to not set up for god performance, since i do set most of the adjustings for Auto....
Now, sometimes the picture has a lot of disturbance, since the scholls of fish and the riggerweights are marked as vertical stripes. I see the fish but the motion is cut off, so it apperars like stripes. Also sometimes a scholl of fishJust dissapears! the transducer seems to stop functioning and after some seconds it comes back and shows the scholls again. Just as the transducer shuts on and off every third second or so. They told at raymarine, sweden, that they never had any problem with the transducers, but the ray dx series have had problems with locking on downriggerweights.
I'm asking around because i'm trying to find out if the transducer is crap and then reaplace it and get another fishfinder instead.
Thats why i wonder if furuno has scimillar problems on the software in their machines.
And no way, i can set up the machine to show a picture as looks like the other fishfinders i've had before this. I like the digital stuff! But the software seems to be poor in them! / thanks

Terve Jussi,


I think the 600 series has a setting for salt and fresh water, change that to fresh water since the salt content there is minimal, if you're fishing in the baltic or the gulf of Botnia, also lower the gain and play with the scrolling speed (to get rid of the "stripes") see what happens.

The 600 is a good unit but the xducer..., I would change that into thru hull like B60 not much extra and the performance is from another planet.

Päivää, Grumpy Finn.
Heck, what a nice boat you got what fish are you after with it?
Thank's for the advice. I'll try to play with the gain, but there isn't any setting for salt or freshwater, still i just fish in baltic sea occasionaly. Neither can i adjust the scrolling speed on the unit since it's either on or off. Only thing left to look at is ducercables connection to the unit. I have already done that, though there could be something wrong on the pins. Also the ducers angle probably have to be pointing more forward. I have seen some guideboats having their ducers pointing twice as much forward as the manual is stating. Maybe that could solve the speadreading as well.

Samoin kuin myos sinne,

I would take Birdmans advice on the xducer wheel and just smash it, I have a P-58 rigged in the transom for a DS400 that's located next to the trolling motor, never got anykind of reliable speed reading except through NMEA.

Hyvaa Vappua, T: Olli

I think you can go into the System Set Up to change the salt to change the scroll speed. Your manual speaks to the shape of the marks being dependant on the boat speed. Find the scroll sped (it's expressed as a %). I don't think there is a special adjustment for salt/fresh water. The manual says you should be able to use a high gain is clear deep water. The Auto mode should be OK.

Now the clutter that you see that happens intermittently is probably a result of the position of the transom mounted transducer. You may be catching air from something on the bottom of your boat like a strake, through hull fitting, or even the motor. Another possibility is that the transducer is mounted slightly too high. Finally, try pointing that transducer down, or as you say, more forward (I think we are saying the same thing)

I tried to find the adjusting for the scrollspeed on the DX600, but it isn't there. Its's either ON or PAUSE. It's differnet on the C and E-models with the dsm unit installed. Lot more features that way.
I found one of the pins in the ducerplug little bit jammed, straightened it out, grounded the little black, bare cable on the powercable to ground and hopefully it will work better tomorrow. I leave the ducers angle so long - glue will not be dry till tomorrow! Thanks for the input. / Jussi......lohien kauhu ;-)

Howdy boys

I installed an Airmar with a paddle wheel to go with a Furuno 620, there's no interference with it as far as marking large fish and or bait fish, heck I mark fish at top speed ( 43 mph ). I calibrated the paddle wheel reading to match my Gamin's 492 SOG. Works as I expected

There is never an "interference" problem with the paddle wheel. They just don't work for very long. Living in seawater, with growth and corrosion, it just doesn't make it.
