Thread: side image question about HB & Lowrance units....

If your unit has the SD card slot, you can share waypoints by moving that card from one unit to the next. This might be something to weigh into your decision. If you have an Eagle and a Humingbird, its gonna be hard to share waypoints.

Actually sharing them on the HB will be easy as well...several options include transfering them by SD card, or if you have two HB's you can use an interlink and it will store and transfer on the fly.

If I were buying another side image it would be Humminbird because there service is hands down the best between the two.

For a transom mounted Si unit I would go with the external GPS Receiver mounted at the rear of the boat as close to your transducer as you can get it. Otherwise you can introduce a position error in your waypoints that you mark using the sonar of up to twice the linear distance between the transducer and GPS Receiver that the unit is using. Make sure you get the 798c Si model and not the 798ci Si model as the extra “I” indicates that it is an internal GPS model unit. With either though you get the faster GPS refresh rate.

Yes, if you are using the cursor to mark the waypoint (in either Si or 2D sonar) it will mark the position of the cursor and not the boat’s position (even works when reviewing sonar recordings).

Not sure what you consider shallow water but it should not be a problem. I’ve seen Si images that show 100 feet outwards from the boat when in 3.5 feet of water. Some of this will depend on the lay of the land so to speak as any bottom that drops away from the transducer will not be imaged. You can look on the Yahoo side Imaging Group web site and some others for shallow water images.

There is no way to network the 480 to a Humminbird unit but converting waypoints from Lowrance to Humminbird is easy. There is a sticky post about this that points to a “how-to” video:

If needed you can also convert Humminbird waypoints to the Lowrance format by using the GPSBabel software.

Like fishindude said: sharing waypoint data between Humminbird units is as easy as downloading the waypoints to an SD card on one unit and loading the SD card in a second Humminbird unit or you could connect both with the InterLink module and it will do so automatically.

when using the interlink will it tell you witch FF initiated the waypoint??Asking because if I am marking waypoints from the Trollingmotor FF and also the console FF then the GPS puck will be in different places and I would need to know where the GPS host is(front or back)

Cuzzin,
As far as using downscan, you will have to use the curser if the brushpile has already moved to the left on your display. If the brushpile is directly below the transducer and is showing up on the extreme right hand of your display, then you can just use the waypoint button. As far as saving waypoints to the card, you page to the Waypoints page and then go to files.

The eagle will have a different connection and would require an adapter if there even is such a thing. I dont know of one, but the eagles dont have the screw in connections on the back, or at least the ones I have seen dont.

Crappiehnt,
It won’t matter which unit the waypoint was marked on as the coordinates for the GPS Receiver that the unit was using will be saved (or the location of the waypoint if you used the cursor to mark a waypoint in one of the sonar views). The coordinates would get shared to the second unit much like what you may do with a friend whom you swapped waypoints with – it is just done automatically is all. Since these coordinates are based on your position on the earth, they can be referenced with any other GPS Receiver as they are all reference from the satellites.

Hummingbird Greg, I have a 788ci combo (internal gps) and am getting ready to pull the trigger on a 998, are you saying that I should get a 998 without the internal gps or adding an external puck. If so how do you hook the external to the 998?

fellas Thanks for the info for sure, looking I think i am gonna put the purchase off a few months till i can afford the bigger screen of either model, looking at em and reading about em i think thats my best bet
