About this app
Marine Mammal Observers mitigate the potential impact of sound exposure on marine fauna during geophysical surveys, naval active-sonar exercises, UXO clearance or, civil engineering projects.
This app will assist the MMO in making mitigation decisions by calculating the distance from the animal to the source of acoustic interference using a trigonometric cosine function. The MMO enters the distance and bearing to the TARGET and SOURCE from their observation position and the app calculates the rest.
This app is loaded with features to allow you to keep focused on the detection (See the user manual for a detailed description):
Fix the compass bearing to the animal and source by pointing the device and pressing the button.
Convert binocular reticules to distance by entering the number of reticules between the horizon and the animal and pressing the reticule button (per formulae in Lerczack and Hobbs, 1998).
Set up to 3 unique observation locations to define height above sea level (required for accurate reticule conversion).
Disclaimer:
MMO Range Finder App should be used as a reference tool and is only as precise as the user's ability to range-find. Any decision-making is the responsibility of the user. If in use, the compass and GPS location should be verified.

What’s new
Several bugs have been fixed, including compass sensitity
New features have been improved:
Swipe left below each text box to clear the data
Shake your device to clear all data
Select your observer location by swiping left or right on the location dots.
Default MIL setting has been set to 10 to match that of most binocular manufacturers
Each location will be set with your custom observer eye-height so the reticule calculation will align with your height above sea level.
