Proper set up for lowrance sonar

What is the best way to set up sonar for best results. there are so many different settings, its kind of confusing. also my unit looses contact with the depth reading and starts flashing weird numbers, it does it more than what it actually works correctly.

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.

Lowrance HDS 10 Insight downscan screen shows a white line across the top of screen. The rest of the screen is blank except for that tiny white line that scrolls at the very top of the screen.

Yes you reprogrammed your unit to bottom depth.
Go to settings and use the arrow buttons until you get to the top of the unit. The menu will have several different settings you need to change the sonar settings. After you play around with all the different settings you will see what I'm talking about.

What are the best settings for a Lowrance Elite 5x for freshwater use only. Applicable to Sensitivity,noise rejection and water clarity settings

Noise rejection = low
surface clarity = off
in the menu, sonar options choose "bottom color tracking white background" this will make the lake bottom appear brown and r he fish bright green.
Automatic sensitivity, but you can adjust it up or down to filter out background clutter and the unit will honor your settings.

How do i find water depth

Water depth should show automatically on your sonar page.
if it does not then either you have selected "stop sonar" under your sonar options or you have opted to turn off the depth displayou so the numbers don't show up.
if you areally viewing your GPS or split screen sonar/GPS page, sometimes the depth display is not visible on these pages unless you specifically instruct the unit to display it.
Lowrance HDS 5 Gen2 Fishfinder GPS Chartplotter
Here is a link to Lowrance where you can download a pic version of the operators manual.
Go to page 11 "overlay data" this will give you a step by step of how to add data or readouts to different screens.

My fishfinder will not continue to read shallow depths as well as in shallow depths when drifting and occasionally running across the water. My unit is a lowrance 522c color gps/fishfinder.

Hello. Your observation is spot on and it is actually a characteristic that is always true when using sonar. Yes, your Lowrance uses the same sonar as a nuclear powered submarine does. The two factors you focus on, water depth and boat speed are perhaps, the two biggest factors when it comes to the quality of the fishfinder. The boat's engine should be in gear at an idle or just above. Experiment with your boat to find the best throttle location for good arches. Usually, a slow trolling speed works best. The depth of the fish can determine if the fish will arch on the screen. If the fish is in shallow water, the fish is not in the cone angle very long, making it difficult to show an arch. Typically, the deeper the fish, the easier it is to show an arch.

Lowrance Lms 522c 5" Screen Color Internal Gps And 200 Khz Sonar

If it is normal in deeper water, it is most likely just returning stuff in the water (debris, algae, anything floating around...choppy water can cause this). Try installing the latest updates from http://www.lowrance.com/en/Downloads/Product-Software-Updates/

If it doesn't help, adjusting the sensitivity or setting the SURFACE CLARITY option from the SONAR FEATURES menu to LOW, MEDIUM, or HIGH...whichever gives the best results.

Lowrance LMS522c transducer

Probably not. Usually the transducer is made specifically for the head unit it is designed for. More often than not, transducers are not interchangeable, particularly across brands. Also, for best results, you really want to install the transducer that came with your new lowrance. That will give you the best results and sonar clarity.

Hope that helps!
