My main technique for recording is to leave the recording gear in the woods overnight. The amount of quality sounds I have been able to obtain with this method has far outdone what I could gather if I were only recording when I was hiking. Overnight recording does require more recording space and larger batteries.

Last time we looked at a recorder that was listed under $360. The next step up is:

Field Recorders under $450.

In the mid-priced range is the Sony PCM-D50.

Conclusion – I have not used this particular unit but those who have appear to think it has many advantages over others in this price range.

– no xlr microphone ports unless you purchase an expensive adaptor box
– records only in .wav and compressed .wav
