I'm saving for a bass boat, and just spending time thinking about what I want. 

 

I'm familiar with basic sonar - down and side imaging. I currently have a Garmin 7SV on my little 10ft boat. 

 

I see "structure scan" mentioned a lot as I'm looking at used bass boats. Is this older technology, or is it still relevant?  Is it proprietary to Lowrance?

 

Does it work with a single unit, or do you need multiple units linked together?

 

I've Googled, but just not finding clear information. 

 

What's the realistic advantage of structure scan for bass/crappie as opposed to a standard $1,000 unit with down/side?

That is structure scan.

So the people who have 2000 model boats with "structure scan add on" are just an older technology when a separate add on was available?
