I have an older Lowrance Elite- 7x sonar/down-scan unit. The conventional sonar has recently stopped working while the down-scan mode still operates as before.

I have a working unit with a bad antenna. Interested?

here is the link to your the lowrance web site. the trouble shooting guide says that if you tried to it on another boat than you might need to take it in for service. but there is a section that explains how to do a soft reset on the unit. you might try that.

Where do you use your boat?

There are so many variables it's hard to fit it all here, but there are some excellent tutorials on the Lowrance website. The most important thing is to pick the right frequency, for the depth of the water. (200khz for less than 70', and 50 khz for greater depths). Depending on how serious you are about fishing, there are a lot of extras that you may never use. The key is to figure out which features will help you the most and forget about the rest.

It's common for SONAR to lose contact with the bottom at high speeds. The better the transducer installation, the faster you can go. Turbulence and bubbles will cause the SONAR to drop out. Lowrance's transducer installation guide explains it very clearly.

SOURCE: Mounting a sonor/transducer on a MinnKota Riptide ST

Did the unit come with a strap to mount the transducer to a bow mount electric? Most units do... If not there is probably one available for the unit as an aftermarket accessory or accessory from the manufacturer... Regarding the transducer wire, just wrap and rout this up the front of the bow mount motor shaft so when you pull the motor up and secure it, it is not going to get in the way. You could cable tie the cord down near the bottom of the shaft and one up near the top where they wont interfere with the motor bracket when the motor is positioned up on the boat.

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??
