Obviously you're an experienced pro, so not much to add.
I do like those buffs. I tried one last year and I'm sold.
I'm curious about having SAR folks doing actual evidence collection at likely crime scenes. You know what you're doing, but usually that's an LEO or tech's job. Are you cross trained? Is the whole team?
The little AA sized ACR C Light is under $10 and does as a passable cheap 360 degree substitute for a real strobe. It's on my extra life vests. My Fenix AA light set to strobe with either the white or red diffuser wand has impressed me as a real attention-getter, too. I use it as a mini traffic wand daily.
That day/night flagging tape is a real find for me. (disaster medical team safety officer)
Thank you for your service.
