Transducer cable length

Hi Chuck,

I am installing a CP370 on a new (to me boat), which has two GPM400/G120, with the P319 transducer. The boat yard installed the transducer and started to run it to the fly bridge, when they realized the transducer cable was too short (by quite a lot).

I don't believe the 5M transducer extension cable (E66010) will be long enough to run up to the fly bridge and through the helm.

Can I connect 2 of these together? Is there a longer option?

Thanks,

Josh
