I Use A Lowepro Format 160 (on sale right now for $29.95 at Best Buy) soft case with shoulder strap, which holds everything, including an extra battery, and a HPRC 2300 ($66.90 at B&H), a lockable, waterproof, hard case. The Lowepro fits inside the HPRC 2300 perfectly and doesn't require you to swap out the equipment! This is my second HPRC case (I prefer HPRC over Pelican, mainly due to the weight/cost differences). I used my first HPRC case (2700) for my Phantoms and accessories, and I loved the quality. I sold the Phantom to purchase the Mavic (took two months to receive). I needed a new hard case for it, so I purchased the smaller 2300 case for it. I love HPRC's hard cases for their stylish design, durability, lock ability, and water proof design (I am a kayaker).
The lightweight soft case is great for short walks before flying. I keep everything I need in the soft case, and coincidentally, the soft case fits Perfectly In the 2300, so I don't have to swap the equipment out of the soft case to put it in the 2300! I lock the HPRC case lid using small locks, and then am able to lock the case to the metal frame of the seating inside my vehicle, so I don't have to worry about theft.
Also, since I don't use the included foam for my drone transportation, I can customize the foam for other type of equipment (photo equip, firearms, etc.) and easily swap out my drone's soft case for the foam when needed.
I think this HPRC 2300 case/Lowepro Format 160 combo is the PERFECT solution for the Mavic, and the cost was very reasonable (about $100, for both).
NO, I DON’T WORK FOR, OR SELL HPRC PRODUCTS; I just really love their product!
