Might want to contact Humminbird_Greg http://www.crappie.com/crappie/membe...bird_greg.html about the interference part.

I have heard stories of the Lowrance and HB models interfering with each other due to frequency tolerances. Here is his work email, [email protected] he is very good at answering emails, but since the holidays is here he might be a tad bit slower than usual, but you can post in the Electronics, trolling motor thread here on cdc and he will get to it that way as well.


On the HDS-7 it will come with standard items like transducer, mounting hardware and wires. If you want a different mounting bracket like a RAM mount so that it can be turned and maneuvered a little better, (which I suggest) you have to get that either from Lowrance or from an online store like Amazon.

I don’t know enough to answer the question completely, but the transducer does the main part of the sonar scan and the unit interprets it for you on screen. They work together so that you can see to the side, cant do it with a different transducer, if that is what you’re asking.


Are you asking about the side scan or the structure scan? Also there is currently two models, with or without "insight". And yes I heard there is a updated model this coming year due out in early spring. But might want to ask someone else on that specifically. New HDS® Gen2 | Lowrance

There is a guy on the forums from Lowrance as well. He posts on the same forum thread as the other but he does not leave his work email, and I have never been able to talk to him but it may be worth a shot for answers to some questions. Don’t rely on a dealer whatever you do! If you need to just call Lowrance with your specific questions. Here is the guys name and profile here on CDC. http://www.crappie.com/crappie/membe...+lowrance.html

Hope you get all your questions answered sorry I could not be of more help.
