Hi and Welcome Jonta. A 4m deep pool is an excellent place to improve your comfort in the water, and as Sanso says, with proper training and technique and a good buddy you can simulate equalization scenarios of 50M depth!

Although I do hate pools myself, I must say that my ocean diving is always better in the months I regularly pool train, and I like the camaraderie of the club that I am in.

Try to get together with a bunch of buddies to train. Maybe there is already a club nearby. Ask at local pools or do a web search.

Good luck
