I Have the DF2120PX, which we like. Don't have the manual any longer. How do I change the batteries? Can't figure out where the batteries are in the unit. Only was able to open the pointing end so far...are both ends supposed to open? Help
The battery is located on the end that the wrist strap is attached to. DO NOT unscrew the transducer side of the unit as this could cause damage to the sensor and sacrifice the waterproofness of the unit.
