The pro tanks are much much easier to re-coil. My opinion though. All areas that you need to work in are very accessible. If you have strong hands you dont need any tools to take apart the pro tanks heads.
I got one of these for rebuilding the coils and rewicking: fluorescent-magnifying-lamp
It is the only way to go if you're going to work with these tiny parts!
Maybe we should plan an 'RBA 101' breakout session after the raffle at the meet this month. Wanna head that up, Serial?
My RDAs arrived yesterday (Octopus) and a wad o wire and wicking (etc.). I'll play with the Octopi... Octopuses... whatever (LOL) sometime today if I get time. I'll probably watch the videos again, but wait to do rebuilds until I get some one-on-one time with someone here locally. (these and the Protanks). I have no idea how to i.d. hot spots and stuff like that. Ugh, moar stuff to learn.
It never ends. LOL
