Deviation between actual and estimated transmitter locations achieved using the gain reduction method (and 3-point triangulation) with an active tracking receiver, directional hydrophone (VEMCO VR100), and acoustic transmitters with 152 dB (n = 8) and 158 dB (n = 7) signal strength (V13 and V16, respectively). Transmitters were placed in various locations throughout a shallow wetland in water less than 3 m deep. A naïve locator determined transmitter locations. Hard shoreline substrate included cobble rip-rap, while soft substrates had gradual sand/mud shorelines or emergent vegetation. All data points are indicated by circles
