There are Video Instructions for some of them - that Ya' should be able to watch also to help with the other "Bridges" etc. too:
As for the "ROO" I'm still searching until I find it maybe someone else who has one can step in and help . . . "You" can also ask at the "Roo" Facebook page (Ohman Bmods | Facebook) where I am sure someone will assist Ya' too . . .
BTW: A " Battler " (< LINK) can be your friend . . .![]()
I see what you did there....

I watched a couple of the vids before the first attempt, and I have a battler. In my case, both floods were caused by user error.
The nautilus bridge is working brilliantly now. I do dread having to swap the coil...
