Trolling Motor Graph

[GoneFishingLTN]

I have a hummingbird 788c at the dash

and a 788ci at the bow. 

I had a simple question I should know. 

 

The front one only works when the trolling Motor is down. So how does this work

 

 

Am I seeing what's in front of me with this graph? 

 

when I turn the motor from side to side is the way the arrow pointing what I'm seeing?

 

should I be able to see my bait if I drop it in front on this system?

The transducer is probably mounted on the motor. It has to be in the water to function. It only looks straight down so it only shows what is directly under the motor. Turning the motor still only shows what is under the motor.

Thank you with these units would I be able to drop shot down to them and see my bait or would I need the newer units?

 

they are dual beams does that just mean 2d sonar?

You should be able to adjust it to see your lure drop.  If it's dropped right under the transducer.

Your bait has to be in the cone for you to see it.  The size of the cone is different depending on the kHz that you are using.  A 200 kHz transducer's cone diameter is approximately 1/3 of the depth.  Smaller numbers make a larger cone.
