When the Nomads were 'new' in zaxcom terms which was like alpha testing... there was the possibility to re charge the AA in the unit. I actually had recharables in the unit but it ended up starting to smoke and as I fumbled to pull the unit out of the bag, open that damn bat door while it was still cabled to everything. I tilted the bag sideways to get the sled out of the unit and I caught it with my hand. The plastic battery sled was melting so the plastic ended up burning my skin. I have a pic somewhere of a perfect oval impression of the end of the bat sled in my hand. Lucky all this happened while I was home testing some bag configurations out. I sent it back to get 'fixed' but then it happened again while i was on a shoot. Completely unacceptable. So I ended up returning it and bought my 3rd 788 and never went down the zaxcom road. While I had the unit I always had to cross my fingers and hope the software boot up would work and the unit would actually start up. Other than that, I liked the device. I thought it was great. But work is work and I couldn't live with that kind of variable in my workday.
