I have a Lowrance Hook 4x fish finder. It has the correct transducer and was working fine. Lately the screen is not showing imformation correctly and it will also start to show a depth of 266 ft.

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.

SOURCE: 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!

SOURCE: lowrance x135 not functioning properly

Had the same issue with another brand. Turned out the transducer cable was picking up noise from other cables (power, trolling mtr. etc). Try moving the transducer cable away from any other cables. I put the cable in a 1/4 " plastic housing up to the point where it was above deck and it stopped all the strange stuff. Not sure about the temp issue??

SOURCE: Marine Faria depth finder, with thru the hull transducer.

I'm having the exact same problem. I spoke with the service manager at Faria (Ted) and he was thinking that as long as the gauge is showing a reading, it should default to reading the depth. I'll probably send the guage in to FARIA - they'll repair it for $55. You bring up a good point - maybe the transducer is bad? I put a call in to the Tedmeister to see what he thinks. I'll post if he sheds any light.

SOURCE: lowrance depth finder missing adapter cable

I own a 1995 Four Winns and what you need is a Lowrance LSM-1 depth finder unit. It accepts the two pin lead from the transducer and send the depth reading to the dashboard display via the 6-pin connector. There is also a three wire harness (red/blk/wht) that connects to a power supply.

The reason I know all this is my depth finder fried a couple years ago so I removed the Lowrance LSM-1 from the boat in order to find a replacement. Unfortunately, this was an OEM part that is not available from Four Winns or any aftermarket source. Probably your best bet is to look in a boat salvage yard or purchase an aftermarket depth finder.
