hi everyone recently doing some freediving and some spearfishing and have some questions

could you tell me how all you equilize your ears because the valsalva pinch and blow technique does not work for me if head down and even normally it doesnt work well

another thing i've come across is just swallowing it works but still a bit hard to do head first

so i've heard of frenzel technique, now i can just not really find good info on how to do it, could you shed some light.

and has anyone else had a problem with equilizing head first
