      LunaBat DFD-1


      Ultrasound bat detector with Frequency-Division type detection (SKU#101, SKU#102, SKU#103, SKU#104, SKU#105)



      (new pictures soon)


      Easy-to-use, small and lightweight ultrasonic broadband detector with frequency-division detection with original amplitude retention function. It allows listening and recording (on an external recorder) the entire ultrasonic range from about 15kHz to over 140kHz, so there is no need for frequency tunning (e.g. heterodyne-type detectors), or manual/automatic starting of recording (e.g. Time-Expansion-type detectors). the ME-3 or ME-4 microphone. dfd1_fr1            dfd1_top



      Now 3 year warranty!


      Thanks to high reliability and simple use, the detectors work steadily for several years!


      Characteristics of the detector:
      • Replaceable microphones for easy upgrade/service/change directivity and frequency response in the field
      • Linear Amplitude Retention System for better signal dynamic and flight identification
      • Very low noise level (SNR>57dB)
      • High quality industrial grade, waterproof (IP-67) microphone connector for stable and long lasting work of microphone without disruptions caused by  the operation under field conditions
      • High quality proffessional grade nickel/gold-plated line-out and headphones connectors meeting the requirements of the IEEE and ANSI standards for good contact and compliance sized sockets with international standards
      • Line-level output of the FD-detected signal (channel L) for recording on audio recorders along with High Frequency unchanged signal (channel R) for direct High Frequency recording on HF external recorders
      • Headphone output with high output level for using even with low sensitivity headphones
      • Optional microphone extension cables 
      • Rubberized side edges to ensure a good grip even when wearing gloves
      • Firm wrist strap
      • Socket with “photographic” 1/4” thread for tripod mounting or for convenient connection with external recorder
      • Lightweight – 125g (without battery and microphone), ca. 150g with batteries and ME-series microphone
      • LED indicator “PWR OK” (lights up in green if the battery voltage is high enough for proper operation of the detector and safe for accumulators)
      • LED indicator “SIGNAL” (lights up in red when the detector detects a significant level of ultrasound)
      • Very low power consumption for long and uninterrupted operation (from 24 to more than 100 hours, depending on the listening sound volume and the type of power supply)
      • A variety of power supply options tailored to individual needs the ability to power: battery or accumulator 9V / 6F22“, optional: with one or two batteries or rechargeable AA cells or 3.6V Lithium-ion type 14500″ (size AA) for a long operation at even lower temperatures

      In case of need to use the usual AA / R-6 cells (primary or rechargeable batteries) with detectors powered by a 9V battery or 8.4V Ni-MH accumulators – these detectors can be equipped with an internal high efficiency and low noise DC-DC converter. Also the voltage level for LED “POWER OK” indicator is changed, corresponding to the level of safe rechargeable battery discharge (1.0V / cell).

      Since the beginning of 2012 year the DC-DC converter is a standard feature in all LunaBat detectors sold in bioacoustic monitoring kits Luna-MINI-2 and Luna-BASIC2. Now also in Luna-MINI-3 and Luna-MINI-4 kits.
