Audio recorders are perhaps the easiest way to collect bigfoot evidence. Therefore I strongly encourage all bigfooters to use some sort of recording device to capture the sounds of the forest at night. Below are some suggestions based on what kind of recorder I have used, or would like to use.
This is the recorder I am currently using both on Finding Bigfoot and in my own research. You might see its microphone sticking out of that backpack with a camera mounted on it that we use on the show’s night investigations. With six inputs, I can use one of the two included external stereo microphones while running up to four other channels into it. There are four input level knobs, one for each channel, and also another level knob on the microphone itself to control the stereo channels together. Sound files record onto an SD card. Four AA batteries keep it running for all night and longer, and rechargeable NiMH batteries work great.
I used the previous model of this recorder for years before upgrading to the Zoom H6 Six-Track Portable Recorder detailed above. The only reason I upgraded at all was because I finally killed the H4N by getting it too wet in Nepal. Still, this unit served me well for the time I had it. Despite my successful destruction of the unit due to maltreatment, it is actually quite rugged. The recorder is a good size, and the recordings are of good quality at almost half the price of the unit above.
This recording unit (the previous model, actually) was in my arsenal for about two years. I liked the size (not too big, not too small) and the ease of use of the device. The recordings sound just fine. This is a totally good unit at a reasonable price.
I had one of these for a while, but it seems that I broke it after dozen or so trips to the woods. While not as durable nor fancy as the models above, this unit offers something that the other don’t which could come in handy for bigfooting. The microphone is omnidirectional and picks up sound from 360 degrees. One usually can’t predict the direction a bigfoot will call from, but using an omnidirectional microphone solves that problem well.
