What boat speed do you usual run when using Side Imaging? I figure slower is better but wondering what most people have found to be the best speed? :scratchhead

3-5 mph for me. It just happens to be where my big motor likes to idle.
Yep same here.....actually seems like 4 mph is just rightQuote:

I've seen SI images from as high as 40mph (with not much detail) ...
I get good results even down to "real slow" ...
Match Chart Speed to boat speed ...

My boat won't go 40 mph. :eek: However, my transducer is bolted to the bottom of my boat (got rid of rooster tail and engine blockage issues) and I git some good looks at 20mph. Rough water, well it is a different story.
why would you ever scan on 455?Quote:

hmmm, you mean wider angle to the sides, or what?
Yes 455kHz has more range - with less detail = better for seeing all the way to the edge of the display ...Quote:

I use each - for what it does best - (dependent on if I want to see detail under the boat ... Or if I want to find stuff farther away from the boat) ...

I'm like Redge 3-5 MPH because i can't idle much slower than that. The old 2 stroke Mercury doesn't like it. I loose my side imaging at about 6 MPH. 50 to 60 ft either side gives best detail, I'm using a HB 998. (I can't go 40 MPH either but I have tried slowing down to 50 several times :witching)
Which is best for Lakes around 10 feet.
I'm assuming your question is pertaining to which SI frequency for your lake ...Quote:

Searching for new structure I want see as much "acreage" as possible to find that new structure ...where I can pop a waypoint on interesting things in the SI image ... This added range of the 455kHz can help locate new structure farther away from the boat ...and I'm not as much interested in added detail right under the boat ...

A common misconception in today's SI units is to be able to put the SI frequency on 1 setting and that 1 setting does "the best of everything" ... It just doesn't work that way ...
The 2 separate SI frequencies are each specilized tools ...each used for specific scenarios ...
*800kHz for interest in detail right under the boat ...
*455kHz for interest in things farther away from the boat ...
And in either frequency choice - frequently adjust the SI Sensitivity setting to brighten/darken the SI image...

THanks for clearing things up for me.
