I ordered two more batteries for it, a charger for 2 batteries and a chest strap With its pros. The choice was between the 5000 model and this one. As a result, after sitting on the forums, I chose 4000 and did not regret it. There are a lot of pumps in the kit - if you buy everything separately, one aquabox comes out to about 2,000 thousand. Be sure to take a memory card 10 - you will see the difference in image quality. Got cons: I don’t see any drawbacks for such a price yet. Except that the sound leaves much to be desired. I ordered a branded external microphone, but it is expensive. Don’t buy any adapters for a simple microphone, they won’t work.
