After having bad experience with humminbird i finally went lowrance, time will tell if they are any better. Seems well built I got this for my hobie revo 13 kayak. Just a fyi this takes a bit more prep in the lowrance ready kayak install. The connectors are a bit large for the through hull mounts. Depth and tEMP IS DEAD ON. Unit works with other transducers so its nice that it can be moed around.

Repeating earlier questions- I provided the wrong email for your response.......

I am replacing an old Lowrance X-4 Pro fishfinder.  It has a six pin plug.  Will the Lowrance Mark 5x Pro accommodate a six pin plug, or does it have a different number of pins- how many? Will it also work off of the transducer from the Lowrance X-4 Pro fishfinder?  

1 Answer
All of the above are now discontinued. We suggest Hook2 4x and changing the transducer altogether.
