Title: optimal setting for different depths of water and speeds?
Post by: akita1 on June 07, 2011, 06:38:52 PM

is there some kind of chart out there that would tell me what to have my unit set at to get the most out of it?say I'm fishing in 14ft of water and drifting for walleye and later I'm fishing for salmon and trolling in 300ft

I dont know of any chart as each unit and its relationship to install will produce different images. Individual setting vary as far as what each user really likes.
I would create a small guiide for your self and carry it with you.
Kinda of like a captains log...

For drifting I would set the Chart Speed to its lowest setting.  When the motor is running try starting with a setting that equals the mph the boat is moving at and tweak it from there.

For the different water depths you should start with 2x to 3x the water depth all depending on how far out you want to see under the water.  The amount of detail you want to show should also influence this as well because the farther distance you show the less detail it can be shown in.

All other settings are really user preference as some can see one color better than another, some like higher or lower contrast and sharpness settings.  Make a Sonar Recording and try adjusting the various settings while on dry land and see which you prefer.
