Kalttoyi 4 In1 Outdoor Survival Whistle Compass Magnifier Thermometer Keychain Travel EDC

Compass relatively accurate. Therm is accurate but VERY hard to read. Needs to be white or silver colored behind Therm so the reading stands out. Red liquid is almost invisible against black background. Whistle is sad. It actually cuts out if you blow hard.

Was a good thifty purchase for my Cub Scouts

Fell much safer now with these on the job
