The Head-Up Display you choose determines what information is displayed at what places on your screen.
|Eagle Prospector (Metric)||10000|
|Elon Interstellar Model E||2500|
|Bald Eagle Racing||50000|
The HAL9000 Hud is yellow, and has monitors that bounce and cast reflections as you crash into things, which is neat. Cargo on the bottom left, a small LIDAR on the top right, and all the normal information divided between top and bottom. Its nice that the right edge of the screen is half empty, because that's where you are are going to be looking most of the time.
The K37 TNTRL Hud is green, and the standard hud for the K37. It boasts the largest useful LIDAR display in the top left, cargo in the bottom left, and normal information screens in the top right. This is a very good hud due to the large LIDAR screen and lack of distracting effects. The bottom right fuel gauge always shows a K37, regardless of what ship you are using, but its sort of a useless readout anyway.
Don't use this. use the metric mod.
Eagle Prospector Metric
The Eagle Prospector Metric Hud takes all the information and mashes it into one big bottom bar. The LIDAR isn't as big as on the K37, but its a very clean hud with lots of space on the edges for you to see where you are going. The cargo display in the center always displays an eagle prospector regardless of what ship you are using, but it alters the cargo bay shape to be accurate, so its not too big of a deal.
The Elon Interstellar Model E Hud is the standard hud for the Model E, and is the absolute worst thing ever created. Its so flashy, so shiny, so futuristic and modern, that its impossible to use in any meaningful way. Hud parts appear in hexagons when they change, and then fade out so you forget they changed. oh and the LIDAR map is overlayed on the entire screen, with the edges (the only important part) being off screen unless you scroll over there. if you hate LIDAR, and love shiny useless stuff, this is the hud for you!
The Bald Eagle Racing Hud is unlocked by talking to a racer and asking where to buy stuff. Its a very sparse hud, with only critical information displayed. Top left is speed, acceleration and fuel. Top right is electrical and reactor temp. Across the top of the screen is a green line for capacitor and a red line for reactor temp. a small LIDAR is in the bottom right, and some of this info is repeated in a box at the bottom. the information NOT displayed is cargo hold (which you can still check on the geology tab), and what components are on or off or damaged (which you can still check in the mechanics tab). This is the best hud.
