Sonar Viewer

The ReefMaster Sonar Viewer is a brand new Windows PC application that combines a multi-channel sonar viewer with the display of side-scan sonar over a world base map. The sonar viewer works with sonar logs from Lowrance and Humminbird units, and lets you view any combination of your available sonar channels with smooth playback at speeds of up to 30x. Waypoints can be created and edited in the sonar or map views, and loaded and saved in a variety of file formats.
The sonar viewer is designed with ease of use in mind; when the application starts, simply select a sonar file for loading - that's all there is to it!

Why use a sonar viewer application on your PC?

  • More Detail
    Sonar logs are typically recorded at a much higher resolution than can be displayed on even the largest units, whose screens are still small when compared to a typical PC. The ReefMaster Sonar Viewer will show your sonar logs with a level of detail that you just can’t see on the water.
  • Easier to use
    Modern sonar units work great, but nothing beats using a computer to quickly control sonar playback, pan and zoom and for creating and editing waypoints over interesting features that you may have missed whilst on the water.
  • More features
    The ReefMaster Sonar Viewer can do more than your unit, including displaying sidescan sonar data in the map view, measuring distances, estimating object heights from shadows and saving image snapshots.
  • More Convenient
    Reviewing your sonar logs on a computer is a lot less hassle than going out to sit in the boat, or rigging up your fishfinder inside. Simply take the memory card out of your unit and pop it into your PC or laptop. You can store as many sonar logs as you like on your PC, and easily switch between them.

Easy to use and highly controllable

The ReefMaster Sonar Viewer is extremely simple to use and easy to control. Zoom in or out of the map and sonar views using the mouse wheel, "zoom-box" or pinch-to-zoom on touch-screen devices. The map or sonar positions can be moved by dragging with the mouse, even whilst the sonar is playing. Image controls such as brightness and contrast are available for each individual view panel via pop-up controls


Flexible Layout

The relative sizes of the map and sonar viewer displays can be easily adjusted by dragging any of the dividing bars, and the individual displays can be toggled on or off. View both of the displays at once, sonar only or map only.


Range of Colour Palettes for 2D and Sidescan Sonar

Work in the palette you are most comfortable with by choosing from a wide range of palettes suitable for 2D and sidescan sonar.


Fast, Effective Noise Reduction

Most sonar logs suffer from a certain a mount of noise. The ReefMaster Sonar Viewer has fast, effective noise reduction that works well without compromising real data. Noise reduction for sidescan, in particular, can make a real difference to the look of sonar data! 


Measure distance and estimate object height

The ReefMaster Sonar Viewer features simple, "click and drag" distance measuring in the map and any of the sonar channel displays. In addition, the height (or depth) of objects in the sidescan sonar channel can be estimated by measuring the length of shadow.
