Hi Tom, I’m answering here (I don’t have your Email address), but please continue our conversation by Email: My contact.

I have been using those UV-B5 continuously for students since 2015, so they have been reliable. I cannot think of  a reason why they would stop working as you get closer to Torrey. I just noticed that I have spare/extra batteries for all the UV-B5’s (and the VX-6R), so all buyers get those bonus items.

I am reserving one UV-B5 for you. Do  you want a holder for $5 more (grand total of $15)? It sounds like I’m pushing fries at a fast-food restaurant. I will have it with me when going flying, and there is a fair chance I will be at Marshall this Wednesday as you noticed from the shuttle list.
