Fish hawk 840 to x4 question.

[Ryno23]

I awhile back I got the x4 probe and was just using it wt the 840 console mount.

I'd like to upgrade to the x4 screen read out on the console this year and was wondering if it has the same power plug as the 840? Hate to buy the screen and find out I need another power plug for it.

Thanks in advance.

I was testing​ 840 Displays on my X4 and Yes they are interchangeable.

Thank you, it seemed to work good wt the 840 screen but than I got a new boat and the speed jumps ard on me now.

Yes the power cord is the same but not all the old 840 transducers will work.  Mine worked on the surface but not down temp.  I got a new transducer and its all good now.  According to Fish Hawk there are only a handful of 840 transducers that don't work, so yours might.  I got unlucky.  LOL
