Feature:1. Receiver: The receiver has a built in induction coil for receiving the magnetic signal from the pipe, and the transmitter head is loaded by the microcontroller and transmits the signal of a specific frequency.2. Transmitter: The transmitter has two receiving modes: far (note: about 5 meters) and near (note: about 1 meter). Adjust the sensitivity knob, peak mode (max) or zero mode (min) to position the transmitter.3. Accurate Positioning: The 512hz locator locates problem locations faster, effectively solving the arduous task of inspecting sewer pipes, gutters, and narrow underground environments.4. Long Service Life: Built in polymer lithium battery, 3000mAh (receiver), LR44/160mAh (transmitter), charging time is 6 hours, battery working time is about 10 hours. 3 level battery indicator light.5. Pipe Inspection: Used for water supply pipelines, air conditioning pipelines, cable pipelines, lead industry pipelines, underground pipeline construction, underground cave exploration, underwater research, etc.Specification:Item Type: Sewer Camera LocatorMaterial: PVCReceiver Frequency: 512HZPower Consumption: <3WDistance: About 5 metersBuilt in Polymer Lithium Battery: 3000mAh (receiver), LR44/160mAh (transmitter)Charging Time: About 6 hoursBattery Indicator: 3 gears, flashes when the battery is lowBattery Working Time: About 10 hoursSignal Strength: 6 levelsSpeaker: SupportDetection Mode: Far/NearVoltage: 100-240V.Package List:1 x Camera Receiver1 x Usb Cable1 x Charging Head1 x Manual1 x Transmitter
