Question about Lowrance X50 Ds Compact Dual Search 83/200 Khz Sonar

Open Question

Flashing depth reading, but no chart visual

Depth flashes, temp and volt is steady. Chart does not show any bottom, surface, fish or structure. Unit is brand new, was showing all until I followed reset instruction in manual, now only shows depth, temp and volts in upper left corner.

SOURCE: x510c most of the time it reads 1.6 for the depth,

Does this occur at any depths...over 20ft even.

The X510c will have problems keeping depth in shallow water...especially if it is muddy, weedy down there.

If the problem occurs even in depth over 20ft, then try resetting the unit:

1. Turn unit off
2. Press and hold ZIN, ZOUT, and PWR until you see the depth (flashing or not) in the top left corner.

If the problem still occurs, make sure the transducer is clean and still mounted so that it is sending the signal straight down to the bottom.

If the problem still occurs, make sure the power is good. You can have the voltage displayed on the screen through the overlay data menu.

Does the problem occur at any speed? If the problem clears up when you stop or slow down, the problem is due to cavitation and the transducer will need to be moved to a location where it is in a smooth flow of water at all speeds.

If none of this helps, there may be a malfunction with the X510c. You can try to update it but you will need to get the software update from someone at Lowrance support and then find a way to connect your X510c to a Lowrance unit that has a memory card slot via a NMEA 2000 network. I can help you with this if you need.

Other than that you can have the X510c returned to the factory for service.

SOURCE: How do you get the fish to show up on the screen

Are you looking for the little fish symbols?
Press MENU, down arrow to SONAR FEATURES and press ENT. Arrow to FISH SYMBOLS and press ENT. Press EXIT twice. Any significant return in the water will now show up as a fish symbol.

Are you looking for the fish arches?
You won't get any arches unless the boat is moving and of course there are fish passing within the transducers signal. The shallower the water, the less area you are covering and less likely to get a fish return.

There is an OK guide to understanding what you see on the sonar screen at the link below. It if pretty technical but parts of it may help you out.

SOURCE: When at speed i tend to lose sight of the bottom

What you are experiencing sounds like air bubbles crossing the face of the transducer. If you have a transom mount transducer check the face of the transducer. Make sure that it is clean. Also make sure the front of the transducer is a tiny bit lower than the back. The digital readout on the screen will only happen when you have a strong signal of the bottom.

Why don't I see fish on my lowrance elite5 hdi fish locator


Sounds like you do not have your transducer connected.
You will know it is working if you have a bottom sounding. If you have a bottom sounding (depth reading) and it is correct then you may have to fine tune the finder to see the fish.
I have the same finder on my boat. http://njsaltfish.com/index.php/captainsfocus?sid=61

How do i get the fish on the screen to look like fish


Your unit should have a setting labeled "FISH ID" turn this setting on and you will see fish shaped icons instead of arches on your screen. You may also see numbers by these icons. Those numbers represent the depth of the fish at that moment.
Be forewarned that at times your unit will show the fish icons when there aren't actually any fish below the boat. Hope this helps.

Got a HDS 5 and im getting bad or false on my sonar when traveling showing fish and structure.When trying to hold ground and im backing up it doesn't even read?i have it on auto sensitivity


Check the mounting and cable connection of the transducer on the stern. If loose will tilt during movement, in reverse wakes from the prop. CAREFULLY check unit during these conditions. The transducer needs to be completely submerged. Good Luck.

Fish finder does not show the fish and can not show the depth


You need to check that the transponder is OK, Check the unit itself, the connections etc, it's just that simple, IF the transponder is OK, then the fault is within the unit itself, accordingly it will have to be repaired by an authorised service center.

don't quite understand what your saying far as the question..when you click the page button on your unit does it show structure scan on the page and if so you go into structure scan and its not showing structure on the screen ?? maybe you need to (fine tune ) your unit or check your transducer to see if its working

When we are deep water (500 ft or deeper) the fish finder will display 3.5-10 ft. and won't show the fish or shows tons of fish. Are we able to set the depth that we would like to see eg: if we are...


Im not familiar with your particular unit but you should be using a low frequency transducer for water over 500'; something like a 50 kHz transducer or a dual frequency transducer like a 50/200kHz for detail with the high freq. but increased depth range on the lower frequency. As far as setting it to 250 ft, you should be able to use the range feature and adjust the maximum to 250'. typically the factory default is automatic so it will caonstantly adjust the range based on the maximum current depth.

Fishfinder 400c?


Hi there.

Ok in WIDE beam mode the cone extends out 45 degrees from the transducer. This covers a fair area, but is best used only in shallow waters as the beam may not have enough power to penetrate deeper waters effectively. 30ft should be fine for WIDE mode however. Using a bit of trigonometry, the beam would extend to a diameter of 60 feet from the center point of the transducer on the sea/river floor.

The beam is a direct beam... It is not a rotational beam from the transducer... i.e. it does not rotate like a radar beam but shoots downward in the cone arc constantly. Imagine a torch being turned on and off very rapidly... The light shoots straight out from the torch in its own cone shape. This is essentially what the transducer does when it shoots out a signal every millisecond or so.

The image you see on the screen is the result of the hole cone of signals, however, the strongest sonar returns occur near the center of the beam. Weaker returns are shown which are located towards the outer edges of the sonar cone where the signal power is less. So if a fish passes right on the edge of the beam, it will only show up as maybe 1 pixel on the sounder screen as it is a weak return on the edge of the sonar cone, whereas if that fish passes under the center of the beam, it will show a larger, more continuous or arched shaped return as the fish moves from the outside of the beam, through the center of the beam, and out to the other edge of the beam under the boat.

Regarding the flasher... I would advise not to use this. It does work by showing a continuous top and bottom reading which displays as constant flashes around the circle readout. Anything it picks up in the beam will show as flashes in between the top and bottom readings. Using the display is far better and with practice allows you to better identify fish and bottom structure readings. Flashers were earlier forms of sonar readouts. Some older folk still like them but I believe the normal display is better for finding and identifying fish and can show structure shape as well (the flasher mode really cannot).

Hope that helps!
