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.
also is there some kind of video that you can watch, that actually shows a professional setting up and explaining how to set up a unit. i have a lowrance x135

Re: proper set up for lowrance sonar
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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

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.

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.
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. If you would like a complete tutorial on Lowrance sonar, go to this link. Enjoy. http://www.lowrance.com/Support/Tips-and-Tutorials/Sonar-Tutorial/
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.
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.
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.
