Hey guys I am new here and I am looking for advice. I just bought a new to me 19ft Hydra-sports.  I just ordered the Humminbird 798 to place on my console and now I am looking for a unit that will compliment that one on the bow. I would like to stay around $600 for it. Less it fine, a little more is fine as well.  What would you  guys suggest?  Thanks

If you're not looking for imaging on the bow, the new 859 is the way to go. 7" screen for 2d and gps/chartplotting. You can connect the 2 via Ethernet. You should be able to find one online in the $550-$600 range. You will need to purchase Ethernet adaptor cables for both units in addition to the cable itself

I think I am going to drop the extra $100 and order the 859ci HD DI Combo. I think I would be disappointed if I didnt.  Is the imaging as good as I am hoping with this unit?

The Down Image will be sharper than the DI on the 798 since the DI units use a dedicated DI crystal.

The DI with a SI unit is computer generated using the two SI crystals.

 

SInce you will be using it on the bow/trolling motor, contact Humminbird BEFORE you open the transducer package to exchange the included transom transducer for the XTM 9 WIDE DI 20 T trolling motor puck.

That transducer is tuned for 83/200 kHz 2D sonar and also has extra internal shielding to combat possible RFI from the trolling motor.

 Bottom line, use the correct transducer for the application and don't "adapt" the wrong one for the application.

Thanks a lot Wayne. I sure would have never known.  Is it an even exchange or is the other extra?
