Turning on my Lowrance LCX 111HD fish locator creates static with my ICOM M502 VHF Marine radio.
I have moved my antenna to the opposite side of my boat from the Fish finder. I ran a dedicated power feed to the radio as it had been showing low battery. I have two different Lowrance fish finders. Both transducer cables run on the same side of the 16ft aluminum boat along with the power feed for the Lowrqnce LCX-15mt locator/GPS. The power feed for the LCX 111HR fish finder/GPS run down the other side of the boat. When I turn on the LCX 111 the marine radio picks up a lot of static.With the LCX 111 on and I turn squelch out the static and then turn on the heater fan the static appears on the radio. When I turn off the LCX 111 and turn on the LCX 15mt it does not pick up static. If I then turn on the heater fan there is no static. If I pull off the tranducer cable intended for the L 111 and connect the transducer for the LCX 15 to the LCX 111 there is still static. Knowing that the power feed for the radio and the LCX 111 are running along beside each other I unhooked the power cord at the radio and supplied power to it by an independet jump start battery near the radio. When I turn on the radio and reduce the squelch to a normal position and then turn on the LCX 111 the radio again picks up the static. Do you have aby suggestions for me to try to reduce the static as I would prefer to use the LCX 111HD locator/gps. I originally had the LCX 15mt on the right side of the boat with the marine radion antenna mounted on that side about three feet away and the radio mounteds on the left side of the boat and didn't have a problem. The LCX 111HD is a much larger unit. Thanks, Leon

Hello LJones0455. From your detailed attempts there are few options. Position the transducers one foward one aft. Connect the negitives of the battiers to the boat still route both positive & negitive wiring to all devices. Check the continunity of your transducers include flexing while ohming. Let me know of the results.

Had a problem with my Humminbird. Took connectors out of cradle and ran direct into unit to check cradle, no difference. Check your getting 12 volts of power to cradle. Did all this and ended up taking finder into a shop and plugging into their set up demo model and still nothing. Unit is stuffed, I'll replace it with similar brand to utilize cradle, wiring and sending unit
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.

This is very common when using a single battery system in
If you more then battery connect the fish finder to the
Or if the Depth finder is connected through the acc. on the
boat. The power is being cut offbe fore
the starter is engaged. By pass this and connect through a correct size fuse.
I don't think your old fish finder is the LMS-332C GPS Receiver listed above in the description. You don't need the speed wheel for the fish finder to function just the transducer and transducer mount. You should mount that on the back of the boat towards the center but not too close to the motor and not too close to the side of the board. Don't let it hand below the level of the boat. That should keep it from getting hit by the trailer or dragging on the bottom. Try to make it as level as possible. The green and white wires may be for the speed wheel but i'd need a model number for clarification. Hope this helps.
