Some real good multi-tools just started to show up:

mostly dedicated to indoor, but can perform some TS functions outdoor; two calibrated cameras, laser, IMU, Snapdragon 820 processor, probably Android (don't know if third-party software are supported), but wonder why not any GNSS chip inside or/and external antenna connector.

200m laser ±0.04 in, Android, third-party software are now supported (nice if J-Mobile could be among them), 360 degree inclinometers, measure on picture, camera targeting, one single 5MP photo camera, Bluetooth, Wi-Fi, no SIM, no GNSS inside when photo stamp needed, etc.

Dual-SIM, Android 8, 8000mAh, IP68/MIL-STD810G, works in direct sunlight with J-Mobile, 6 inch screen, u-blox M8N inside, internal GNSS antenna GPS/GLONASS/BEIDOU, but also connector for external GNSS antenna (better device with inside u-blox F9 high precision GNSS module, in the near future).
With third party photo-capture software, 13MP camera and a good Disto, it helps a lot in the field with inaccessible points. Some good ideas here for Victor LS..
