A:AnswerYes this is the all-inclusive version - PowerDolphin Wizard. It comes with PowerDolphin vehicle, controller, sonar, bait box, and a storage bag.
A:AnswerFirst you find the nearest calibration station. Should be able to Google it. Wow so is an actual surveyors level drone. I am very tempted. 2350 ft. Hmmm
A:AnswerThis thing is actually very quick on the water, and has a lot of torque to power through the surf at the ocean. It's as fast as a decent RC boat... 15 miles an hour , maneuverable, reverse thrust. Quicker than I expected that is for sure.
A:AnswerHandles waves up to 2 ft pretty well. If it rolls over, it's easy to turn upright, even remotely. It's not sinkable unless the hull is broken.
I have not used it in salt water, but I assume it would be fine if rinsed off afterwards.
