I'll checkout the Trubridge, John. Freediving is pretty radical stuff.
Thanks for chiming in, DT...you are right...lots of fun gets had in that pool. The tube suspended underwater they call Parkour Island. I have a right angle to put about 4 feet away...at 2-3 foot section that requires a right angle turn into another 2-3 foot section to transit the piece...kind of an underwater playground.
Here is some footage of playing with the sand jug anchors for the tubes...Hayden is learning to take very quick "bites" of air...good air discipline.
