Final answer:
The most important extra item for a hunter to carry for personal safety in the forest is a First Aid Kit, alongside water, sunscreen, and a cell phone.
Step-by-step explanation:
For personal safety, the most important extra item that every hunter should carry when going into the forest for the day is a First Aid Kit. While things like extra ammunition, portable stoves, or personal entertainment devices might be useful for certain situations, the primary concern should always be safety.
A First Aid Kit can be pivotal in treating injuries until professional medical help can be reached, especially in a wilderness setting. Carrying ample water, sunscreen, a hat, a cell phone, along with the First Aid Kit is advisable for any outdoor activity to ensure preparedness for emergencies.
It is crucial to remember that exploring wilderness or remote areas should be done with caution and preparedness to prevent any vulnerability to dangers that could arise.
