Hello! I am happy to be here and want to get other's advice on skin diving. I am a competent swimmer and I am interested in increasing my bottom time. I currently free dive to about 30 feet deep. In my younger days I used to go 40. My dream is to go 50 feet. I recently bought a pair of long fins which made a huge difference. I mostly ab dive. I have a spear gun but rarely am I able to find fish. I dive in Sonoma and Mendocino Counties. I am 51. I have been ab diving since age 15. I grew up on a swim team and can swim very well.
