DJI Mavic Pro review.



The Mavic has been the drone on everyone's lips over the last three months, and since it's release DJI have struggled to keep up with the demand.

Pre-orders were underestimated, and the manufacturing line was exhausted to get the Mavic out in a timely fashion.....but that didn't happen!
DJI are still drip feeding the UK market with one or two per order every week and they are becoming even more popular.

Luckily I managed to get hold of mine this week!

The first thing I noticed was just how small the Mavic actually was! Completely different to the phantom, it'll fold down in to the size a sports bottle and in it's folded state, it comes in at H83mm x W83mm x L198mm.  It's light too weighing in at only 1.62 lbs (734g), so with these small dimensions it is the ultimate personal drone to carry around with you. Even when the Mavic is in the carry bag fully loaded with three batteries, it still doesn't feel like a burden to carry around.

Don't be put off by the weight though, as this really does feel very sturdy. The underbelly has doubled up as a metal heat sink, so that gives it a more refined feel.
The legs fold out to its full size, and the movement is very fluid...no nasty knocks or noises, or looseness either.

Now, they say on the DJI site that it is capable of an 8 mile flight distance, but that isn't to be confused with controlled flight distance. The Battery will give you 28 minutes of flight, and 8 miles is roughly how far it would go before falling out of the sky from a full charge. Realistically, it'll fly upto 4.3 miles in a controlled manner where it will transmit control functions and video transmission.
It uses DJI's new transmission system called Ocusync which can give the 4.3mile range when FCC compliant, and 2.5 for EU users. It was designed to enable 1080p HD streaming over short distances, and 720p over long range, allowing total real time control of your Mavic.
I have noticed that compared to my Phantom, the streaming images haven't dropped out or had any glitches in the live feed....at all!

It hovers SUPER stable, I mean it doesn't move at all......it's perfectly happy sitting in the air for the duration of it's battery if you needed it to, BUt, if you need it to shoot off ASAP, then flick the sports mode button and it'll propel itself to upto 40mph.

The collision avoidance system works brilliantly. It is extremely accurate and can sense solid objects up to 50ft away. It'll stop and avoid objects in as little as 2ft proximity.
In follow mode it will even utilise the under belly sensors to monitor the elevation changes in the ground below.
One point to raise is that the Mavic DOES NOT HAVE a manual button to flick into ATTI mode, which means anyone who wants to use it as the equipment of choice on a CAA approved course, will be refused.  Inside flight is very stable although does, at times, drift slightly.


The handset is like nothing I have ever seen or used before. It is an awesome design and feels perfectly ergonomic to hold. It does have a flaw though.....you will use upto 50% of the handsets battery in two flights, which doesn't sound so bad, but when you consider the Phantom's handset doesn't require a charge until your at least 10 flights in , it becomes noticeable.

It is all designed around being a hi-spec, portable and personal drone though, so you have to take the rough with the smooth, DJI have tried to accommodate all aspects of drone flying, and some things had to be cut.
I can't imagine it being the primary drone on a commercial basis, but, I can see it as a back up? It will still shoot in upto 4K, and take stills at 12 mega pixels, so it does contend with the big boys in the end, and it still has the same flight characteristics as a Phantom or even an Inspire.

By the way, the Mavic now uses GPS (American standard positioning system), and GLONASS, the Russian equivalent, but miles better. This enables a VERY accurate Satellite positioning system in the Mavic, and makes it a very precise flier.

Overall, I think that if you have the cash and are in the market for a Hi-Spec, compact, and portable drone then the Mavic is the one to have.

I have absolutely fell in love with mine,  and it'll  be my summer adventure companion for a long time to come......well, until the Mavic 2 emerges!
