Bail Mounting a Device with a Swivel Base
If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer when the screws are tightened.
You can install the optional swivel base (included) on the bail mount, so you can turn the device for a wider range of viewing angles.
NOTE:
The swivel base is not available for
ECHOMAP™ UHD2 9 sv models.
