Tech Support - No Bait / Bottom
Nothing shows but a light at the top
In most cases this is an issue with the transducer. There’s either a break in the connection somewhere or the transducer has completely lost sensitivity.
To test for a break in the connection turn your unit on and hold the bottom of the transducer to your ear. You should hear the transducer clicking. If it is not clicking there is most likely a break in the transducer cable somewhere. The most common breaking points are right at the transducer itself or by the connector. While holding the transducer to your ear try wiggling the cable at these points to see if you can get the transducer to start clicking again. If you find a break in your wire further than 4 inches away from the transducer you can send it for repair ($15.00 labor + $10.00 shipping). If the break is right at the transducer there is unfortunately no repair it will need to be replaced.
If the transducer always clicks yet you still only get a light at the top the transducer has probably lost its sensitivity. Unfortunately there is no fix for this and is best to replace the transducer.
The best way to verify it is indeed the transducer is by getting a second known good Vexilar transducer. Plug this transducer into your unit. If everything works without problems it further confirms you have a transducer issue. If the second known good transducer still has the same issue it’s likely there is an issue in the head unit itself. At this point it’s best to send the head unit in for repair. This kind of failure is rare and it’s hard to say exactly what it is. Cost could vary from $30.00 to $115.00 in most cases.
Cannot see jig unless I turn the gain way up
Most of the time this is due to a weak transducer. The best way to confirm this is to get a second known good Vexilar transducer and hook it up to your unit. If this fixes your issue its best to buy a new transducer. Unfortunately there is no fix for weak transducers.
If you put a second known good transducer and still have sensitivity issues you may have an issue in the head unit itself. If this is the case send the unit in for evaluation. Typical repairs can range from $30.00 to $115.00.
Remember the environment you’re in and the equipment you are using can play a big role in what you are seeing. If the jig isn’t within the cone angle or if it’s on the outer edges you may have a hard time seeing it. Current, a minnow swimming off to the side, very shallow water where the viewing area is very limited or a transducer that isn’t hanging vertically can also cause this.
AZ bottom disappeared
If you raise up the transducer more than a foot when in AZ mode, the bottom will disappear off of the screen. Also, if there was a very strong fish target below when you switched to AZ, the unit may have locked on that as bottom. When the fish swam away, so did the "bottom". Simply reset the AZ by switching to NORMAL and then back to AZ.
There is no bottom in AZ mode
You must have the range set deep enough to see bottom on the NORMAL view and there must be red in the bottom signal in order for the AZ to obtain a lock. Increase the depth range and/or gain level until the bottom appears and shows red.
Keeps losing depth or goes into the 300ft scale
Losing depth intermittently usually means there is a connection issue with the transducer. The most common breaking points are right at the transducer itself or by the connector. To test this turn your unit on and hold the bottom of the transducer to your ear. You should hear it clicking. Wiggle the wire at the common breaking points while it’s up to your ear. If you can cause the clicking to start and stop you’ve found a break in the wire.
If you find a break in your wire further than 4 inches away from the transducer you can send it for repair ($15.00 Labor + $10.00 shipping). If the break is right at the transducer there is unfortunately no repair it will need to be replaced.
You can also try getting a second known good Vexilar transducer to put on your unit. If it fixes the issue you can safely assume you have a transducer issue.
For FLX-28 owners in Auto Range: Any time you move the transducer you are changing the depth, forcing it to recalibrate its range. The unit will default to the 300ft range while recalibrating the depth. This can also happen if you have a weak signal or don’t have the transducer below the bottom of the ice.
