The Carter Parchute float really opening up and the last energy pull by the spent shaft.
If the fish were still on the end of the spear, the C02 activator is ready to be pulled.
Notice the line attached to the C02 activator is at its best position, ready to fire.
The key to this Carter float good auto inflation ( D ring for 90 degrees pull is a must ) when set as mine is to allow at least 1 ( 3.3 feet ) to 1.5 meter (5 feet ) of travel from its "velcro-ded" position to full opening via water resistance before the C02 fires.
I have not yet made custom made velcro holder for the Carter float, it was from my Riffe utility float holder. What I don't like for now is : the 2 of the C02 cylinders sometime hit each other underwater and makes a loud noise. If I can make ( soon ) a custom velcro holder, that noise can be prevented and will make the float even better when folded or carried around.
Once you get used to it, bringing this Carter float around like the way I do is not troublesome at all ( for scuba I mean ). For the freediver I think a floatline + float is better. But if the current is very strong and the freediver is capable and hunt depth of greater than 70 feet, this set up is much lighter to drag around. If I can fight current with this float set up on scuba any freediver with it will outswim me easy in strong current.
