Marcum Technologies Radar Detector LX i User Manual

To Use on Ice  
Congratulations on purchasing the most advanced hand held digital sonar ever made. The MarCum LX-i  
can be used to shoot through ice, single layer aluminum boat hulls, fiberglass hulls, or can be used from  
inflatable watercraft.  
Clear snow from the ice so you have a clean surface. Place a small amount of water on the ice  
and couple the transducer to the water / ice by applying gentle downward pressure while  
pushing the ON button. Three dashes will appear in the LCD display. The unit is now in Active  
Bottom Search Mode. When bottom is found, it will be displayed on the digital read out. Once  
the bottom is found, the unit will automatically enter Fish Mode. In Fish Mode, the unit will  
actively search for approximately one second. If fish are found, the unit’s alarm will activate  
and the digital display will flash the depth of the target seven times. The unit will then revert  
back to Bottom Mode. The unit will rotate automatically between Bottom Mode and Fish Mode  
until the unit is either turned off or the unit can’t find bottom at which time it will shut off  
automatically within fifteen seconds. To turn the fish alarm off, depress the ON/OFF button.  
Ice with air pockets (crusted snow and water that freezes) can make it difficult to obtain depth  
readings. If this situation exists, try other nearby areas until better ice is found. If poor ice  
continues, a hole may have to be drilled to check depths.  
To Get Started  
Remove the battery door located on the lower backside of the unit. Insert a coin into the coin slot and turn  
counter clockwise. Place the coin under one of the slotted corners and apply gentle upward pressure until  
battery door opens. Place lithium CR-P2 battery into the molded battery compartment. Replace battery  
door by applying gentle downward pressure with your finger while turning the coin slot clockwise until you  
feel a gentle click. You are now ready to use the LX-i to obtain depth readings. The battery will last  
roughly twenty hours of continuous run time or multiple years worth of depth readings.  
To Use in Boat  
To obtain a depth reading through a boat hull, place water in the bottom of the boat. Make sure that the  
transducer face has enough water to eliminate any air between the transducer face and the bottom of the  
boat. Another method is to coat the bottom of the LX-i (transducer) with petroleum jelly and couple to the  
bottom of the boat. To obtain a reading over the side of a boat, hold the transducer in the water 1/2 to 1  
inch and push ON. Be sure to hold the unit exactly vertical or the reading won’t be accurate.
