Lowrance electronic X59DF, X52 manual Speed/Temperature Sensors

Speed/Temperature Sensors

Optional Temperature Sensor

All the units in this series can display water temperature from a single analog sensor. Your unit comes packed with a transducer with a temp sensor built into it. If you wish to purchase an optional additional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual.

However, please note that the Sonar socket on your unit is designed to read only one temp sensor. Since your transducer contains a built-in temp sensor, attaching the optional temp sensor to your unit's Sonar socket will override the temperature information provided by the transducer's temp sensor. Your unit will only display the temperature provided by the optional sensor.

Optional Speed Sensor Installation

All the units in this series can display speed and distance traveled, but only the X59DF comes packed with a speed sensor. If you wish to purchase an optional additional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual. The following instructions describe how to install the speed sensor.

Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit

for pilot holes, screwdriver. Required supplies for this job include: four #8 stainless steel wood screws (3/4" long), high quality, marine grade above- or below-waterline sealant.

First find a location on the boat's transom where the water flow is smoothest. Don't mount the sensor behind strakes or ribs. These will disturb the water flow to the speed sensor. Make sure the sensor will remain in the water when the boat is on plane. Also make sure the location doesn't interfere with the boat's trailer. Typically, the sensor is mounted about one foot to the side of the transom's centerline.

Once you've determined the proper location for the unit, place the sensor on the transom. The bottom of the bracket should be flush with the hull's bottom. Using the sensor as a template, mark the hull for the screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.

Mount the sensor to the hull using #8 stainless steel wood screws (not included). Use a high quality, marine grade above- or below-waterline sealant to seal the screws. Make sure the sensor is flush with the bottom of the hull and tighten the screws.
