Head unit ticks with transducer

[brettw]

Anyone ever put an ear on the head unit. My HDS unit clicks right along with its transducer.
My Garmin doesn't so I'm wondering if this indicates the Garmin has a problem.

My Garmin does it and my old Onix did too. My HDS Gen3 doesn't. Just depends on the unit I guess.

so, i'm learning ticking or not ticking is not an indicator of proper working order.

thanks,
