Here's some help understanding what's going on in the images above.



Here is inaction photo drop shotin'



Here's the Baits and you can see weight and swivel tied up and ready to go Drop Shotin'



Here is the Drop Shot Rig I used showing the Swivel, Bait and Weight and how the graph can show each on the screen.

Here's some neat clips from Louie Bartenfield from Georgia: http://www.carterslakeguideservice.com/videos.html

Fish directly below/in the center of the cone of the transducer will show up as the strongest return. The Far Right Side of Images I have the Strength of Return Scale turned on, the top is the strongest return (red) to the weakest returns at the bottom (blue). IF you look at this image below. The left side is the oldest data and the right side the most current. There is only one main fish easier to interpret



If you look through the transparent numbers under time you can see where I picked this fish up with the sonar it was on the outer edges of the sonar as it was blue/green color representation. The fish starts moving closer as I drop my drop shot rig see the line changes to a yellow color. You can see I held my bait steady at around 15' until the fish moved into the center of the cone and you can see the drop descend to the fish. He come up takes and look and swims away. I tried to raise the rig to entice but the fish is gone.

This is one of the reasons I use Original Color Pallete because you can easily see the strength and location of the fish in the cone angle. Because the Red color really jumps out when the fish is dead in the center of the cone angle.

This is a tough color pallete for me because it's harder for me to see the strongest returns from the fish in the center of the cone. Everything blends together Yellow, Orange and Red blend together.



Other reason when the fish are sucked onto the bottom you can see the thin yellow/blue line that is a fish sitting against the rocks on the bottom. See how one rises up to come check out the bait and how he moves directly under the transducer.




Here's what I love to fish...Suspended Fish over deep water you don't have to hunt the bottom for the fish...



If you really want to get very accurate with vertical fishing you use Clear Mode which filters out side lobe readings and become a very precise sonar sonar system a little harder to keep the bait in the cone angle but when you see a fish and drop your bait and see it you are hitting the fish in the head or the tail because of the precision sonar system Humminbird Clear Mode Sonar is.



Here's a Vertical Fishing reward...big fat spotted bass

Using Side Imaging and Down Imaging makes it easy to find these bottom hugging fish then you get on top of them.

Need help we where to mount transducer. Here are couple of photos of the back of my boat. I have the 798ci hd si HB. [/img]

As close to the livewell intake as you can get it and not be inline with a hull rib. Up against it if possible.

Are you replacing the current transducer? I would mount in that location. BUt recommend getting one of the poly-Mounting Boards so you can make adjustments without having to drill new holesall the time. IF mounting low you need to keep the distance away from the motor like the op manual says 15" so you do not disrupt water flow to the outboard cooling intakes.

Yes I will be replacing the current transducer. So it will work in the old location as well so long as the view is clear for the side image.

If your motor is trimmed down all the way it might not work with the si (or might have a shadow). The pros will let you know.

I finally made the swith to SI. I have a 997 getting delivered today and will start the install tonight. Below is a pic of my 79 Ranger. Should I install the SI transducer in the same spot as the previous one. Also what size SD Card are people using with the units? Thanks and great info here...

That is a good place to start but it will be suceptable to damage from underwater obstructions...the HDSI transducers are not cheap but that looks like the easiest install with your configuration.

Thanks

Hey Gonzz, theres a spring loaded mount that'd be good for your application. It's is this section under transducer saver, you should be able to find it easily. Nevermind heres the link to it.

Thanks for the info. I got the unit installed just wating for new transducer to get here on Thursday and it's fishing time.

What size SD card are people using in their units? I need to pick one up this evening.
