If someone can explain the safety feature of this squonker, I might just add it to my stable of a Gayscano 50w and five reos.
I just do not see what happens if, dog forgives, a short develops and causes a battery mishap.
I just ordered one, but hopefully I'll never find out the answer to your question. The negative contact looks to be spring loaded, whether that would act as a hot spring... no idea.
For the record, I've always wanted a REO, but it's never been in my budget. I still want a REO and hopefully some day I'll be able to get one. Looking at the design of the owl atty, I'm not sold on how well it will work, so I may end up ordering a bf atty from reosmods anyway.
