Olex have long been the go to 3D seabed Mapping chartplotting system.  Now Olex have introduced the Olex OS1 Blackbox fishmapping echosounder.  

When connected to an Olex with the OS Software Module and a transducer, provides an echosounder with a unique twist. An adjustable window on the screen, shows the fish, and bottom just like a traditional sounder. Using the OS software module, Olex remembers every ping and creates a map of where the fish has been so that you can predict where it will be in the future.

Olex Managing Director Ole Benjamin on announcing the OS1 said "we think this is an innovation in the use of echosounders. Our focus is not on replicating all sorts of bells and whistles, but provide a practical echosounder and expand on the fish history and useful statistics.'"
