The hds units all come with a sonar transducer as well. So you buy an lss-1 with whatever hds unit you buy and you will have all you need. Now, if you want to link two separate hds units together which is what I have done, that will allow you to do many things. One advantage to that is you can have one sonar transducer on your trolling motor up front, one sonar in the back for the backseat guy to see as you fish or for you to see if you are driving. The lss-1 transducer is best mounted on the rear of the boat and its linked from the lss-1 to both hds units for side/bottom scanning at either unit.If you are planning two hds units however there is one more thing you will need to buy and that is an ethernet cable for Lowrance.Its like 35 dollars but well worth the investment if you are using two hds units. I can set a waypoint on one unit, and it automatically puts it on both hds units. I have the hds8 up front for me to see while fishing and an hds7 at the console. I really like my Lowrance units and I find new spots to fish all the time that I never knew was good spots. I spent alot of time looking at both before I went Lowrance and I have been well pleased with my units. GCF

Are you sure about the HDS5? I thought I read that it was the only one not capable. But I could be wrong again.
