Humminbird and Lowrance at the same time?

I currently run a Lowrance LCX 26 and am wondering if I could also run a Humminbird side scan unit at the same time? Or, is it one or the other?

Absolutely you can.

One of the things you can do with the ‘birds is select which frequencies you want to display. To reduce interference with other traditional units, you could choose to display only the 83 kHz portion of the 200 + 83 combination that HB uses for looking down (since most other traditional units transmit at 200 kHz). Your bird will display the 83 for looking down and the 445 for looking to the sides.

Thanks for the info Jason. I just ordered the 797c si from profishingsupply!

Here’s how to do it:

With the unit powered up and running, press the menu key twice. This will bring up the main menu system.

Use the Right arrow on the 4-arrow button to select the Sonar tab.

Highlight Beam Select under the Sonar tab (using the 4-arrow key to move up or down among the different menu options).

Use the left or right arrows to select the desired beam configuration for the down-looking sonar. In your case, you want to display the 83 kHz beam.

I have run an older Lowrance and an older HB unit side by side in the past… There was interference, but it didn’t really make me miss anything. I just mentally sifted the interference bars out.

I ran my older HB with the new 997 last time out, and had near zero problems. I didn’t try the old lowrance with the new 997 – I assume it might affect the 2d sonar a bit, depending in settings as Jason mentioned… I would also suspect that it would hardly or not at all affect the SI, but it is yet to be tested.

There should be zero impact on SI, because the SI frequency (455 kHz) is so much different from traditional down-looking freqs (typically ~ 200 kHz).
