We do not currently support the use of hydrophones with Song Meter recorders.

Prior to late 2020, we sold hydrophones from a third-party manufacturer and our own custom-built adapters that were necessary to connect these hydrophones to the Song Meter SM3 and SM4 families of recorders. We have discontinued these products and have none remaining in stock.
