Depth Gauge for Glastron MX180.

[daqddyo1]

Hi,
My dealer is a bit vague about installing a depth gauge for my new outboard.
Does anyone know the brand and model of the gauge normally installed in the MX instrument panel?
Hopefully the transponder sits in the floor of the boat. Is there a recommended dealer for this instrument (either in the U.S. or Canada)?

Thanks,
