great to have you here. I personally don't really care about the design of the housing, but I can see why it could create unnecessary attention. I once got whisky coolers in form of revolver cartridges and security at the airport had to consult with their supervisor, even though these things were so clearly not real cartridges. I would transport the device in a pouch anyway, so I would not expect security to be too nosey. Perhaps offering a rugged pouch is also something to consider for you/your company.
About trefoil: I'm thinking about replacing it by a triangle. I'll play a little bit with shape and post here several variants.
rugged pouch: currently, this pouch(case) in included: https://www.instagram.com/p/CE82YYwpbHq/
I have registered on the website to be informed when the device will be available (which says May). Perhaps you could also let us know when it'll be up for sale?
First bunch of devices is quite small. Tomorrow I'll send a message to the first emails from the queue(emails left on the website).
Next bunch will cover current email list and a little bit more. It should be ready in May-June.
Write me by email or pm here, so I can check when you be able to order.
And as Raysid is only 250 km from where I live: Would it be possible to pick up the device in person?
Sure. No problem with that. Just check border/quarantine rules.
I have access to a number of calibrated sources. Would that be something helpful for you?
Yes, this is interesting. I could add new isotopes to the library and make activity(in Bq) measurement of them (currently only Cs137)
