North-West European Coasts Heightfield Bathymetry charts for TZ Professional v3
PBG Module vs. HD Heightfield Charts
While the HD Charts are great for getting better quality images to ultimately help fishermen to understand the seafloor better and make more informed choices, the PBG module goes a whole lot further.
PBG stands for Personal Bathymetric Generator and requires a sounder + GPS in order to produce your own rendering of the seafloor.
The difference between the PBG module and the HD charts is that HD charts do not provide the same high quality as a PBG, however no sounder is required.
One of the top advantages of the PBG module is that it will also allow you to create marks to pinpoint the best fishing areas so that you can easily find where you were when you hauled in a great catch.
Other advantages are the dedicated 3D workspace and the Fishing workspace allowing for incredibly powerful 3D rendering of the seafloor to help visualize the bathymetry better and tools allow for the adjusting of isobars and color-scale.
Another important factor is that the HD chart only covers the North-West European Coasts and so this means that it is exclusive to fishermen navigating in these waters.
Take a look at this image comparison of the same spot with one image coming from HD charts and the other having been taken with the TIMEZERO PBG module.
The PBG module is now accurate to a resolution of 1.5m x 1.5m.
