798 Down Scan

I have had the 798 Ci for a year or so and did not realize it had down scanning capabilities until i ran across this web site. one question – how well does this option perform on the 798?

reason i ask – i was thinking about purchasing a unit with down scan capabilities – and was wondering what a suggestion would be – with price definitely in mind? Thanks in advance for any help.

You should be able to see it in the menus, you may have to go to the Humminbird Website and see if you have the latest software. http://www.youtube.com/watch?v=-TZtvcpzQRM

thanks for the reply – i watched the video and a few more. can you use 2 transducers on the 798? – right now i have one on the trolling motor – which of course is useless when using outboard.

You are lookong at using 2 SI transducers front and rear?

This must be a SI unit correct, and you are running the big SI transducer on the trolling motor? I am a bit confused, but nothing new there. If you want to run two transducers there are a couple of options. There is a Y cable that was made for guys running a glass boat that want to shoot one ducer through the hull, so the traditional sonar will work while up on plane, and still have the SI ducer mounted on the transom so they would have SI while going slow. This Y cable splits what information is used by each transducer to the head unit. The through hull ducer would only be used for traditional sonar, and the transom transducer would be used for SI, DI, and temp. There is also a kit to run two seperate transducers with an A-B switch that would allow you to switch between the two SI transducers. If you are wanting to run 2 SI transducers the switch would be what you would want to use.

yes – assuming the down scan is decent on the 798.

the kit sounds like what i need. i may go to outdoor world and see if they have it. can you recommend a system that would be compatible with the 798? i’m thinking of getting something for the console. i currently use the 798 up front for spidder rigging ( it may be i need to move this one to the console and get the other for up front – or see if i can add an additional mount for the 798). thanks for your advice.
