Do you need to...
- record less than a minute at a time?
- change sample rate/filtering several times in a deployment?
- record at different times on different days?
- time-synchronize for localization?
- store more than a terabyte without servicing the recorder?
If you answered yes to any of the above, you need an SM3.
Otherwise, the SM4 is the right choice:
- The SM4 is quieter so it will record more of the sounds that you want.
- The SM4 is half the size and weight of the SM3.
- It features new, easy-to-use scheduling blocks that meet almost every need.
