I know it may sound selfish of me for insinuating-
But it could be argued that he doesn't believe the Pendellum will work, and therefore it's a failure.
However, let's no linger on terrible notions like that. I would like to think that all Magick Tools shoud be approached from a Harry Potter standpoint, which could be stated in Ollivander's Words:
It is the Wand that Chooses the Wizard, Mr. Potter.
I use that Philosophy with all my small, scrounged-up equipment and so far they have yet to fail me. I have a wand/staff tool that I was led to and, out of pure luck and intuition, pulled it from it's burial place within an empty field (no trees around. It was simply a pull to the middle of a Field to dig for something, and I did it... And voila! A never-failing Wand/Staff!)... I hope I'm not coming off as a shotty kid again.
Give it time, Kits.
Or go back and have him Choose. Gifts are good and all, but sometimes they can all be scored in the Internet sonet of "FAIL" if they aren't meant to be. The Vampire friends I met use what they call "Vampire Tools" which, are the same as the tools I use really (Athae, Chalice, etc.) ... However I know the value of the Caster-Tool relatinship and I don't press on the issue too much.
POINT OF MY RAMBLINGS:
Make it noted that, though Gifs are good, they might not all be down to an exact science of astrological connections and resonance, so to speak. Resonance and connection could be on a past-life level aswell or some other nonsense that we cannot fully comprehend the value of True Connections.
Good luck though, Kits!
