Freediving Computers

Freediving computers need to be able to data at a much faster rate compared to scuba diving computers which might only record dive data every 20 seconds. Some scuba diving computers do offer fully-featured freediving modes that provide information to the second but unless you scuba dive as well you end up paying for features you won't necessarily need. Dedicated freediving computers provide only the features that a freediver would need, typically making them cheaper.
