Samsung micro-SD cards are not supported!
The SD-cards we recommend and have tested to perform the best are:
Sandisk Extreme Series
Sandisk Extreme PRO Series
Sandisk Extreme PLUS Series
We recommend the minimum speed rating of the micro SD-card to be U3.
The U3 rating on SD-cards looks like this , and is found as shown on the picture below (the red ring):
Maximum supported size is 128GB.
The Paralenz Dive Camera will only perform as well as its Micro SD memory card allows it to. If the SD-card is not U3 rated we can't guarantee the performance and you may experience freezing problems, especially when recording in higher definitions.
