Humminbird Transducer Question

Is it possible to run a HB 798 and a HB 717 on the same transducer with a splitter?

No it is not.
You could use a Unit Switch (US3) and run one unit on the transducer than switch it over to the second unit but not both at once.

Thats what I had in mind...Just using one unit at a time. I am wanting to use the 717 at the console for depth when driving the boat and the 798 in the front of the boat while fishing. I just wasn't sure if the 717 would work properly on the 798 transducer.....Thx Greg.

I looked up the US3 to order it on the Humminbird website. The description says "This switch connects two fishfinders to one transducer. This switch includes three cables: 24 inches to the transducer, approximately 4.5 feet to one unit and 20 feet to the other unit."...Maybe I am understanding this wrong, but the first cable listed says 24 inches to the transducer...So is that saying that there is a 24 inch cable that the existing transducer cable will hook in to?...Then the other 2 cables will go from the US2 to the 2 units?...I guess I had it in my head that the existing transducer cable would hook into the US3, then 1 cable going to my unit on console and another cable on the unit on the front of the boat.

TnT,
The 717 can work on the 798’s transducer. It will ‘see’ it as the standard DualBeam transducer that it normally ships with.

“I guess I had it in my head that the existing transducer cable would hook into the US3, then 1 cable going to my unit on console and another cable on the unit on the front of the boat.”
That is how it works TnT. The length of the cables connected to the US3 are 2 feet for the cable that your transducer will plug into and a 5 and 20 foot cables to run to each unit or in your case: unit mounts. It does not mean that the switch has to be within 24 inches of the transducer itself – just the transducer plug so that they can be connected together.

Thx for clearing that up for me, Greg.:highfive
