Connecting a gen 2 touch unit to older gen 1.

Currently I have a HDS 7 touch at the helm networked to a hds 5 gen 2 at the bow, they are linked together with a network cable to share waypoints and the side imaging.

I was thinking about purchasing a used gen 1 HDS 10 to replace the HDS 5 gen 2 at the bow but I Have a few quick questions I am hoping you guys can answer.

First question is can I link the touch unit to the gen 1 unit like I am currently doing with the gen 2 hds 5?

Second, do the older gen 1's use the same power cord as the gen 2? So if I did purchase a gen 1 unit to replace the HDS 5 gen 2, would I have to run a new power cord for the gen 1 unit or could I use the old power cord from the hds 5 gen 2 unit?

I am just trying to make sure that I can just remove the HDS 5 gen 2 and mounting bracket and really just put a gen 1 HDS 10 or so in its place without having to rewire everything.

Only reason I am thinking about this is the gen 1 HDS 10 units are starting to get really cheap, like $600 or so for a used gen 1 10 inch unit.

All you will have to change is the mounting bracket, the wires will plug right in.

Thank you very much for the reply, its greatly appreciated.

Now all I have to do is sell the 5 gen 2 and pick up a 10 gen 1 :)

I got one for ya.

If I only have hds10 at console how would I connect another HDS 10 to bow? Do you wanna have transducer on tm for accuracy to be right under you jigging? Also would tm transducer be 2d only or could you get down image also? Or would down image come from stern transducer the structure scan?

Yes you should be able to do what you are thinking. The power cords are the same. They will network also.

You already have Structure Scan installed? Either way all you have to do is run a Ethernet cable, either from the console unit to the bow unit or from the SS box to the unit on the bow. IMO a bow unit without a transducer of it's own is useless, so yes I'd put a 2d transducer on the tm. Unless you install another SS box or Sonar Hub on the bow or move you current SS transducer to the tm your SS image will come from the back via the Ethernet cable.

:hesaid
Justin hit the nail on the head. Yes, you could put a bow mount up front without a transducer but the only views you are going to get are from the back of the boat. With a bow mounted transducer and a stern, you can pick and choose which one to view from your front mount unit or your helm unit. If you own (or are planning to upgrade) to a new minnkota, get one with a US2 sonar built in. Makes it nice when you don't have to hard mount a transducer to the TM.

The us2 will that do structure scan? The console unit already has structure scan so I'll do another one on tm and Ethernet them and can choose between front or back correct? Also would a HDS gen 2 on bow be same way? Is there enough difference between gen 1&2 for extra $$

The US2 is 2d only. Gen 2s have faster processors and have a couple features the 1 doesn't. My advice would be to buy a Gen 2 Touch in whatever size you want then put a HDI transducer on the TM. This will give you DI and 2D up front.

K I didnt realize you could get them with di only and not SI

A gen2 touch with 2d and di only probably lot cheaper than SI combo I guess they call it?

Was reading in other post about lowrance cords not fitting terrova eventually what I'm buying. Guess HB would BS better on bow?? Justin?

IIRC the other post was about an Elite 7 HDI not a HDS. ANY HDS unit regardless of generation will work with US2, remember US2 is 2d only and has nothing to do with DI/SI. I'm not familiar with the Terrova but if I remember right there is a groove in the shaft for the transducer cable to run in. The LSS 1 transducer cable was to large to fit in the groove, the LSS 2 cable is smaller but I don't know if it'll fit. I don't know how the HDI transducer cable compares, but I can't see it being any bigger than a LSS 2. Brian at BBG marine would be a good guy to ask what will and will not work with the Terrova.

Thanks Justin
The boat I'm getting has older miinn kotta pd on it I'm thinking it'll be perfect for long lining.

I have a HDS gen1 8 and a gen2 8. Either one will work on the bow of my boats. I have a terrova with the built in sonar. on the pontoon and a Fortrex on my crappie boat. The only thing you will need is a short (about 7-8 inch adaptor cable) to connect the wiring from the terrova to your HDS unit. If I remember, their like 20 or 30 bucks.


The next thing I can see you getting is point1 (if you don't already have it). That is a game changer....well worth the money. Had a lcg4000 before the point1. Was ok, but the point1 is just so responsive to boat movement.

What is a point 1

point1 is lowrances current "top of the line" gps antenna for the hds units. It has a compass integrated into the gps system. If you have been on boats and the boat is trying to find a predetermined brush pile a lot of the time you need to wait for the "boat to catch up with the cursor". With point1 you get immediate response from your gps due in part to the compass located in the unit. When you turn the boat your cursor turns with you.
