I was looking at buying the 798, I have several questions, they have a 798C SI and a 798 CI SI, I believe the CI has an internal antenna, and the C does not, does anyone know for sure, and what is the benefit of one over the other?

Also, I am a novice by all means, I fish a 2200 acre Rez, and rarely do local tournaments, but I need a decent fishfinder and I figured why not go for it and get the SI. Does anyone see any pros/cons to spending so much for a novice angler fishing a fairly small body of water non-competitively?

Also any advice on temporary mounting the transducer would be very helpful

I just bought the 798ci.. That means it has an internal antenna.. the c model has and external antenna that needs to be mounted.

I bought the SI model and have heard wonders about it. Basically the consensus is buy the biggest screen you can if you are getting a SI based on your budget..

If you only fish one place SI could help but I couldn't justify that type of money to not use the gps functions as well.

The transducer on the SI is normally harder to setup because it has to be able to see out the side of the boat.. The instructions that come with the unit are very extensive..

Good luck as I love my unit..

Thanks for the help.  Mass, might I ask where you bought it and how much you payed?  

I looked online and a local company Anchorexpress.com They are the cheapest around as you are getting 10% off.. They are local to me too so I was able to get in in 1 day..

I would go with the 798 without the nvb and then buy a new premium card from navionics..

If you need any other help let me know.
