Yes, I believe that you can, but don’t put the screen part or the transducers of the systems close to each other. Sometimes two such units can cause interference with one another. You could see about getting a switch for the transmission cable but I don’t think that they use the same electronics.

To be sure, call the Lowrance Support Section at 1-800-324-1356 and get the correct way to accomplish your installation.

Please let me know what you find out.

I could NOT fine any information on a Humminbird 1179, but I did have information on the Humminbird 1197. Could you have reversed the numbers when describing the model of the unit? If so, the 1197 Combo series comes in FOUR DIFFERENT varieties, which range in price from $2600 to $3000. One of the differences is the type of transducer and the use of dual transducers with the units. Another is the face that some come preloaded with Navionics marine charts. I mention this in order that you select the proper one for your type of work. The 1197c SI Combo NVB CHO features a 10.4' display, Side Imaging and DualBeam PLUS sonar with up to 8000 Watts PTP power output, GPS Chartplotting and advanced Fishing System capabilities. Includes unit cover and in-dash mounting kit. This model Includes select Navionics Charts pre-loaded. This product does not include a transducer.
It is billed as a fantastic Side Imaging~dual bean sonar with plenty of power.

Both manufacturers of the units you describe indicate a much improved view of structure and of the bottom contours than some of their older units, however remember that the High Definition Screen (HDS) designation usually means a better rendition of the SCREEN images. In order to get these better images you will almost certainly need a unit with the right type of transducers and one that has the capability to “punch through” the water to give you the results you need.

I suggest that you visit the respective manufacturer’s web site (www.lowrance.com & www.humminbird.com and view the specifications on both of the units you mentioned. You will not that some of the units REQUIRE a separate Structure Scan optional accessory in order to get the best results. This accessory would connect to a HDs unit via a cable to greatly improve the underwater images.

Both of these web sites have images and videos of their unit in action.

After narrowing down your choice, visit a stocking dealer and view the unit and speak to a competent technician about the capabilities of the unit.

Before spending that amount of money on a unit, I would be sure that it will perform as required for my type of application.

I would also call both of the companies to get their view on the type of unit that would meet your requirements. Try the Support sections at Lowrance @ 1-800-324-1356 and Humminbird @ 1-800-633-1468 for their suggestions.
