Forward Scan Sonar mod Description This mod adds a sonar to the game which you can use from any ship. This can be useful if you have ever unintentionally grounded your ship or crashed into underwater objects. Also it can be used for searching for objects at the sea floor. Modes of operation Sector Imaging Mode - scans a 180 degrees sector with a very narrow vertical beam. Signal strength is mapped to display intensity, displayed range is not corrected (slant range). This is best suited for searching for objects on the sea floor and for making images. Sector Depth Mode - scans a 180 degrees sector with a wider vertical beam. Depth of each point is mapped to display color, displayed range is projected. This mode is more useful for navigation in shallow areas. Basic Forward Scan Mode - scans area directly ahead of your vessel with a vertical beam. Position of each point is displayed on distance-depth graph, giving you precise information of depth right ahead of your vessel. Although you can see only a small area of the sea floor, this mode has the fastest refresh rate. NOTE: * Wherever the depth is displayed in the device, it is not the true depth, but depth below sensor position which is located at the bottom of your vessel. * Sector scanning modes might degrade your frame rate. If you are having bad performance, reduce the scan rate. How to enable When you are in a ship, use the "Sonar Options" action in the action menu. Options Mode - sets the mode of sonar. Range - sets the maximum range of the sonar. Max Depth - sets the depth limit for the display. Only affects basic forward scan and sector depth modes. Image Gamma - Allows you to adjust gamma correction of the image. Only affects sector imaging mode. Scan Rate - Allows you to adjust the scanning rate of the sonar. Only affects sector imaging and sector depth modes.

And every time I do so, I can't stop thinking that the game doesn't have any proper equipment to operate boats. In real life most boats at least have a simple depth pinger. Nowadays there are even cooler devices, such as forward scan sonars, which don't look directly under the vessel, but also ahead of it. More expensive models can perform a good 3D scan of whole area ahead of ship. I also happen to be a sonar developer in real life, so I just couldn't not build one it in the game 😛. The mod works by using ray casts to simulate operation of a real sonar. Because of that you can not 'see' what is lying behind tall objects on the sea floor. Also you are going to see 'shadows' of objects which are on the sea floor or suspended above it (like submarines). To-do list - Figure out a better place for the panel so it doesn't obstruct anything - Try to make a 3D scan sonar done Comparable real life devices Basic forward scan sonars: Simrad Forward Scan: https://youtu.be/O6B-OvjQIQ8 Echopilot FLS 2D: https://echopilot.com/products/fls-2d/ Navigational 3D forward scan sonar: Farsounder Argos series: http://www.farsounder.com/products/argos-350 Imaging sonar: Teledyne SEABAT 7123: http://www.teledynemarine.com/SeaBat-7123-MkII
