Fish Hawk Lithium Multi System, negative reviews wanted

[RH93]

I'm ready to move on from my old moor sub troll unit. I bought it used when I first got into salmon fishing, but its time for a upgrade. I cant seem to make it a whole season without the coated cable getting damaged, leaving a large clump of coating to get hung up in the antenna and then destroying it. 

 

I'm looking at the Fish Hawk Lithium Multi System, I believe it replaced the old X2 system? Although I don't need a portable unit, I really don't want to drill any more holes in the transom for another transducer, and the slip ducer seems like a good alternative. I'm looking for negative reviews of the unit. Any problems with the slip ducer losing signal with the probe? Any cons to the slip ducer set up?
