PBG Introduction

The "PBG Module" needs to be unlocked to access this feature

The Bathy Recorder (also known as "Personal Bathymetric Generator" or "PBG) enables you to record sea floor topographic information using your Sounder to incorporate that data into your personal 3D PBG database. When you use PBG, the 3D data will constantly improve with repeat trips over the same areas, enabling you to have a perfect picture of important sea floor terrain, as well as your favorite fishing spots.

In addition to rendering your data in 3D, TimeZero with PBG module allows you to display depth shading (color according to depth), custom contour lines with complete control over the density, and a depth profile window.

If you have a Sounder that can provide Bottom Classification, Backscatter, or Bottom Hardness, TimeZero will also record this information at the same time as the depth and be able to display bottom hardness in color over the chart.

PBG can be done with any single beam sounder (TimeZero just needs to receive a depth value) or with a multi-beam sounder such as the Furuno DFF-3D or WASSP system. The advantage of using a multi-beam sounder such as the DFF-3D or WASSP is that you will be able to cover a much wider area and collect many more points more quickly.
