Hey all, I recently got a spare air "pony" and I had a question for dive shop owners or anyone who has filled one. They fill off of a fully charged cylinder. I normally rent my tanks and own everything else. But if I rent a tank and use it to fill this, it will not be full anymore. Can the shop top it back off before I dive? Is this common? And is there normally a charge for something like this? Sorry if it's a silly question, I just wanted to know what to expect when I go next time.
Thanks,
Thanks,
