Here is a video showing the Eagle Tree Systems onscreen peramiters or sensors readouts that are on my Neptune sub.They are lower left prop speed in RPM fard and in revse.
Main battery votage hen RX voltage,top is the depth readoutit has not been connected yet soon will it will rise in numerick value as the sub dives and is extreamly accurate!
The 3 bars are the 3 battery level indicators that are available I only use one and have iliminated the rest in future runs,it will decrease in size and shows the persentage of battery life left like a gas gage nice!
Bottom is the motor temps ,reads dirrectly on the motor port side no need to sence the other motor.Then the ESC temperature ,both these readings have pree programed high temp alarms and trigger an alarm that is audible bepping and a text that says ESC is overheating slow down or stop ,I can make it say what ever I want same for the motor.
A very fun and easy way to know whats going on in your sub.Love it,later I might try the GPS system ,it has a huge host of stuff like a compass and home arrow readouts along with climbrate ladder ,just like a full scale ROV .
Also the tilting of the camarra gives excelent forward and below view.
