If they dropped a measuring device down there, something akin to a deep sea satellite, how long would it take to reach the bottom?

Is the device powered or is it like a stone? I say a stone would decent much faster then a powered vessel (those can't descend to fast due to pressure).

Like something with the weight and density of a bowling ball. Something would stay down there and transmit info...then after a while it would either shut off, or a central part of it would pop out with a air bubble-type balloon and a flag.

The last measurement was taken in 2009 by way of sonar

"The most recent (1 June 2009) sonar mapping of the Challenger Deep by the Simrad EM120 sonar multibeam bathymetry system for deep water (300 - 11,000 meters) mapping aboard the RV Kilo Moana, has indicated a spot with a depth of 10,971 m (35,994 ft) (6.82 miles depth). The sonar system uses phase and amplitude bottom detection, with an accuracy of better than 0.2% of water depth. [1] [2]"

Ok, with that info and Cap Eq data I would caculate 2.36 hrs. I can do the caculations when I get to work tomm if so wishes?

One of my favorite movies!!!

Hahaha I was watching Stepbrothers a few days ago and was cracking up at the scene where John C Reilly (whose character is a total bum) tells his therapist, "I work at a college as a janitor even though I feel like I'm smarter than most of the people that go there. Sometimes I see an equation written on a blackboard, like half an equation, and I'll just figure it out."

Wanted to try something similar

that air bubble would be like a football field sized balloon by the time it got to the surface..so hows a football field sized balloon going to float with an air bubble in it when its at the bottom?

I bet Dorian would sink to the bottom faster than Ronnie.

Ronnie's sinking ability is unmatched even to this day.

Dont know, some type of smart balloon/air bubble. One that can regulate the air/density within and around it so that it can ascend upwards. Or some sort of propeller/miniture rocket at the bottom of the device to aid in the ascent as well.
I'm thinking that as I said, the device would be ejected out of the "deep sea satellite", which itself would be akin to a bowling ball (weight, density, size). In this would include measuring devices that take in all pertinent data ( depth, currents, density, life, minerals, etc). These devices would be located in the core, which would pop out.
