Have a small backpack which is normally very close by just in case there's caches around containing:
- UV black light torch
- a magnetic flashlight
- pocket knife which also doubles as a 4 in 1 screwdriver
- telescopic magnetic pick up tool
- spare batteries
- powerbank for phone/GPS
- gloves for creepy crawlies guarding GC
- various spare logbooks
- spare ziplock bags
- SWAG of many sizes
- pens and sharpie marker
- hand sanitizer
- muesli bar, snacks, juice and medications for t1d
- notebook for field notes
- measuring tape
- log roller
- cable ties
- tweezers
I think that's everything?
