Wakulla Springs B-Tunnel Video (WKPP)

the double suex unit dives fine. very weird to dive. very FAST.
I did some line work in wakulla with the thing last week and it was....different.

As it's (the one i dived) a camera platform, it has a slow start system that takes some getting used to along with all the extra mass and quirks

He lives on the edge. He fills his LP tanks beyond 2640psi. He can use whatever duct tape color he wants!

GUE's gotta GUE.... It's like not having a Wakulla patch on a DUI. I hear they kick you out for that stuff.

Can you describe "weird?" Props rotate the same way or are they counter rotating?

In my mind, counter rotating props like a Piper Seneca, turning towards the center of mass, would negate any negative effects if you lost one of the scooters. Would also make the camera platform super duper stable.

no they are two regular scooters and the triggers are attached by a delrin rod.
there is some flex in the rod so when you hit a trigger, that scooter starts a little bit sooner than the other. so, for a second, the whole thing goes diagonal. then the other scoot kicks on and it straightens out and if you have the speed up, it takes off like a rocketship

I think maybe a steel core in the rod or maybe a carbon fiber rod would stiffen things up and fix it, but i'm not sure if it's a big deal for their prospective customers. too rich for my blood so I am not one of those people

Crazy cool!

Thanks for sharing.

Could the PVC things be markers to recalibrate the inertial reference of a mapper used in a previous survey?

Re twin scooters: Counter-rotating propellers only lessen the effect of p-factor and that is not an issue in diving. One way to deal with the yaw resulting from only one scooter working is to remove the dead one, ditch it, or tow it behind. I am certain that the connections between the scooters and to the lights and camera could be designed to be reliable, rigid, and easily reconfigurable.

that could be. the USDCT used some wacky mapping thing in there I think

Yea that’s totally possible.

There’s all kinds of weird historical stuff in Wakulla. I spotted a 3-4” floating washer that was tied to a teeny little weight in the grand canon room the other day. Very strange.

Googling USDCT I found this

Nice find. That seems like what those tubes are for.
