Moor SubTroll 900 & Fish Hawk 840 on same boat?

[landingzone]

Just a wild thought.... I have two functional Fish Hawk 840 setups. I plan on selling at least one and buying a Subtroll 900. I will likely sell the second Fish Hawk unit also, however, I was wondering if anyone had any experience with operating both brands on the same boat. I don't know if their signals would talk to each other (interfere) since one works via the cable and the other via transducer.

LZ, I used my Cannon S-n-T along with a Fishhawk before and didn't have any problems. Pretty sure the Cannon and Subtroll are similar as to how the signal is sent.
