Topic: 798c HD SI and a 998

[hgv]

I have a 798c HD SI mounted at the console and have been thinking about picking up a 998c HD SI unit. I would like to move the 798 to the bow and put the 998 at the console.

so option 1 was to move the 798 to the front along with its transducer to the trolling motor, then add the 998 at the console and its new transducer to the transom. Issue is I only have one Hot Maps card with all my fishing spots loaded.

option 2 move the 798 to the front but network it to the 998 to get access to the Hot maps card and just use the one transom mounted transducer

any recommendations?

I don't think you have a clear understanding how map chips are used, versus waypoints/tracks. 

Map chips (navionics, lakemaster, etc) are not shared between networked units.  Each unit still needs it's own map chip.

Waypoints, tracks, routes are not saved on the map chip.  They are saved internally on the depthfinder, and can be exported to an SD card.  That SD card can then be plugged into any unit, and have that unit import those waypoints/tracks/routes. 

So you could easily put all your fishing waypoints on both units, without having to network them together. 

And whether they are networked together or not, you will need to own two map chips to have the lake contour map displayed on both units at the same time.  Or, you can move 1 map chip back and forth between the two units depending on where you're fishing.



Your option 2 that you mentioned, if you have them networked through ethernet, you'd be able to have a transducer on the front and one on the transom, and either unit could read the sonar from either position.  But you still wouldn't be able to share 1 map card.


Hope that helps.

Your InterLink™ Network Connection allows you to share accessory data, GPS position, waypoints, routes and your current track between two Humminbird®
Fishing Systems in real time. When sharing is enabled, for example, you can mark a waypoint using one Fishing System, and it becomes instantly available
on the second Fishing System

Interlink and Ethernet, are two different networking options.  They ARE different. 

For one thing, sonar data is shared between networked depthfinders over Ethernet.  Sonar data is NOT shared between networked depthfinders over Interlink. 

A Navionics HotMaps chip is not shared between two units, no matter how they are networked.  You'll need a separate map chip for each depthfinder.



However, as you mentioned, waypoints, tracks, and routes ARE shared between networked depthfinders. 

It you are planning on networking them together, don't even mess with the Interlink system.  You can do WAY more by linking them through the ETHERNET method.  Plus, it's way cheaper if all you have to do is buy an ethernet cable, and a 700 series ethernet adapter to hook up the two units you mentioned.


I basically have the same network you're talking about doing.  I have a 788ci HD networked to a 998c HD SI, and an I-Pilot LINK trolling motor.  It's pretty nice to mark a waypoint, and instantly have it show up on the other depthfinder.  But, like I mentioned, a single map chip is not shared between two devices.
