Hi to everyone !
Up to now I have mainly experienced dynamic apnea in swimming pools..
A little bit of diving pit (20 m) with water 27-29 °C warm..
A little bit of constant weight and sled in the sea in July

(26-28°C at the surface)
I shall be soon experiencing constant weight in cold water

(less than 14°C)...
I am a bit worried about my ears

...
My question is : to what extent is COLD WATER + DEPTH a handicap for the ears ?
Thanks for your piece of advice....
