Many operations call for audio recording and a transmitter can not penetrate the surrounding area. This is where the DAR1004 is perfectly suited. At less that 1/3 ounce you will hardly know you have it. This small recorder can be enhanced with a external microphone for line quality audio. The double tap record, stop and playback buttons ensures that the unit can’t be accidentally stopped at a critical time. Comes complete with ear bud, standard watch batteries and computer connection cables. Call us and ask about larger memory models.
