First Aid Kit vs. Survival Kit
First aid focuses on treating injuries; survival kits focus on shelter, warmth, signaling, and water. Rockhounds benefit from both, but they solve different problems.
Bandage Kit vs. Trauma Capability
A basic kit handles small issues; it may not be adequate for major bleeding or fractures. If you collect remotely, consider adding items that match your risk level and training.
Vehicle Kit vs. Pack Kit
A trunk kit is helpful, but you may be miles away when injured. Carry a smaller kit on your person when you are away from the vehicle.
