Cable won't pull out
but over time as it flexes against the hard plastic of the transducer it
will wear and fail right at that point. Often the failure is internal and you can't even see it unless you strip the insulation carefully on a post mortem. The guys I see hole hoppin' swingin' their 'ducers like they're walkin' a dog have to go through one at least every couple, three seasons.
Or maybe they just sell it to some poor schmuck and buy the latest greatest.
Just like any appliance or power tool that gets moved around a lot. Sooner or later it fails and 999.9 times out of 1000 it's the power cable and the failure is most often right at the plug or where it enters the tool. Your transducer is no different. I know some of them have been re-enforced with Kevlar and such but it's still a concern.
That's why the extra cord, not so anyone wouldn't get "sued", just to take the abuse off the transmission cable and place it on something more durable and easily replaceable.
Y'all will do as you please. I'm just sayin'.....
