Can anyone recommend a good freediving computer? I am working with a budget, and all I am really looking for is dive time and depth, but something reliable. Since I need to order everything, I cannot just go around to a local shop to fix things.

Hello I’m getting into the sport of freediving and more importantly it’s going to lead into spearfishing whenever I felt like I built up the necessary skills . I just wanted to know what is the proper swimming technique when using freediving fins like the C4 MB002 carbon fins? Also when it comes to breath hold and training to stay under water for longer periods of time. What is the proper way to train ? I want to build my lung capacity and also get use to holding my breath and staying under the water for longer . Any advice is helpful !

So I don’t really freedive in natural locations but this seems to be the best place to go for answers after posting in snorkeling. I got this mask from Walmart about a week ago simply for pool use and they’re leaking water. I’ve adjusted the strap multiple times ranging from completely loose, less loose, to all the way tight and no matter what it leaks. It seems like the water is leaking from just the outside corner area of my eyes. I’m not sure if the silicone is too flimsy and isn’t sealing properly or if they just don’t fit my face. I would like some advice.

Edit: When I did the test where you breathe in to test for suction it had fit and made perfect suction but when I put it on with the straps the part that goes around the corner of my eyes pushes out, as I described the issue you guys I realized what was going on thank you for the help.
