It depends wether you are doing specific training for freediving.I'm on the market for a watch. After going through the options I'm between Cressi Drake (270~ Euro) and Suunto D4F (~280). Also suunto has the added cost of battery replacements unless the internet replacement kits are okay?? Does anyone use them himself? Also as I understand it the Drake has some extra features, are these features something I will miss in my diving if I choose the Suunto?
I have looked at the features of the D4f and they are not even close to what the Drake has to offer. I personally train at least once probably twice a week next to freediving/spearfishing in the weekend and I can say that all the training functions and different programs are super nice features! I love the Cressi Drake in every way and would recommend it to anyone.
With our freediving club we are doing specific pool exercices and this watch allows me to keep track of my performance and adjust accordingly. Also I can program surface time intervals or max depth times or ... basically whatever I want.
The Suunto D4f only has a chrono as a training feature! For that price they should have come up with something better I think. If you look at the features it has to offer there are better options out there that are much cheaper. I think with the Suunto you ar buying the name of the brand.
