New unit

[brush pile]

Gentlemen I have probably stepped out of my league but I went and bought a lowrance touch9. I am very computer illiterate and cannot find where to change sensitivity. I can change contrast but that's as far as I can get. Could any body help on how to accomplish this and what settings (contrast included) to get the pictures they have advertised. Thanks a lot

I think the clarity of the pic depends on the water. Ive tried to get my pics to looks just like those advertised but this is the closest ive gotten which isnt bad.

BrushPile,

I don't have the same unit so I might not be that much help in that regard but.... I know if you go to Lowrance.com and click on support they have contact information. Email the contact folks your question (ensure you have your serial number) and they will email you back the exact info you need.

I had an issue last week that no one could figure out. Quick email to them and got a response at 11pm. Tried it the next day and it worked like a champ. Instructions are usually short and simple with exact menu buttons to push.

Ok,
I just had a rather large weekend celebratory drink so my comments may be off.
But, I think the contrast is the sensitivity on my 9.
At least that's how I use it.

Ok, sitting in the boat, will do a few tests.
Settings: Sonar: shallow water, downscan overlay, on
Navigation: logging type, time
Time period, 1 second

Sorry, not much help but I'm not on the water.
But I do think I use the contrast like sensitivity.

Don't expect to get screen shots like the manufacturers advertising all the time. Too many variables. They are showing shots in the best conditions and good structure. I'd say stick with the default settings till you find the right structure, under the right conditions. Then mess with the settings and see if you can make an improvement. Keep in mind the settings that work the best under one condition, might not work so well in a different condition. They don't have default setting for the heck of it. They put them there to help you get started with the best results.

Find a good piece of structure and mark it well with buoys...

Then scan it from several different directions using different settings each pass...

Scanning the same structure over and over eliminates the "Enviromental" variables (water changes, depth changes, bottom composition changes)...and gives a better understanding of what unit settings affect the image in certain ways...

Take notes of what each settings change does to the image...

I still use this same testing procedure as much today as when I first bought my unit...(especially when testing some of my experimental xducer setups)...
