It seems like the deeper the depth the longer I can hold my breath, what's going on? Am I giving my CO2 receptors a good workout and just can't feel it as much? If I can hold for 4:00 min at 5 meters down then I should be able to do that on land right?

My PB on land is 2:55

What the hell you can do 4min at 5m, but only 2:55 on land. maybe you are getting a huge dive reflex or something. Are you diving in cold water.

Figuratively speeking, I was actually doing dynamics for the first time at that depth and was able to go 17 meters farther than usual (40 meters) and it felt better, same warm up and everything. Do you need to dive a certain depth for your dive reflex to kick in?

i thought the reflex was due to cold water and pressure and something about the spleen contracting when diving. But yeah im not a tech info nut someone else should help you out soon.
