Garmin GPS 125 Sounder - Manual (Page 72)

Mounting the GPS 125 Sounder (cont.)
• There should be at least 2.00” (5.0 cm) clearance
behind the case to allow connection of the anten-
na, power/data cable, and transducer cable.
• The mounting surface should be rigid enough to
support the unit and protect it from excessive
vibration and shock.
• The GPS 125 Sounder screen has crisp contrast in
most lighting conditions, even full sunlight.
To surface mount the GPS 125 Sounder:
1. Place the mounting bracket in the desired location.
2. Mark and drill the four mounting holes for the fasten-
ers you are using.
3. Fasten the bracket to the surface using the appropri-
ate fasteners.
4. Insert the GPS 125 Sounder into the mounting bracket.
5. Screw the two mounting knobs through the bracket
and into the GPS 125 Sounder.
6. Connect the power/data, antenna, and transducer
cables to the back of the unit, making sure the locking
rings are fully tightened on both connectors.
