do you have any picture?
fathom talk about to put it in the T of the breathing loop... but don't see any picture...
23" is the default length from the battery pack for the hud (can be changed)
right now the machine is disassembled for maintenance, will try to send pictures when I reassemble it, in a week, +/- , work and wife allowing.
Anyway, there is not much to see, it is just attached to the loop by silicone straps. The battery pack is placed
so when finning/scootering forward, pose minimal drag.
