Planning to go freediving in Batangas

Planning to avail courses from freediving schools in Mabini Batangas. So far, Ive narrowed down my choices to these 3 Vertical Freedivers, Freedive Pinas and Freedive Tribe PH- do you have any experience to share with any of these? Also, is it advisable to go diving in October? Really looking forward to learning how to free dive as a non swimmer who loves going to the beach but always has a life jacket on. Thank you!!
