Can someone recommend a book or video course on snorkelers who want to dive down to a reef 30-50 feet deep and stay on a reef for a few minutes. I am not a pure free diver for sport. Just need some tips on extending my breath holding on reefs.

I highly recommend that you consider taking a freedive class which will teach you many important techniques to extend your "safe zone", but you will also learn how to recover a buddy who has had a problem and also how important it is to dive with a buddy who will watch you and be able to assist.

This is a great book written by my friend Dr. Terry Maas and I can recommend it highly.

However, freediving to 50 feet (let alone a 2-minute dive time) is a much different activity than "snorkeling" and it should be approached with all the respect it deserves.

Agreed. Instabuddy isn't a good idea for free diving. Especially spearfishing.As one who has suffered shallow water blackout in a swim team underwater swimming competition in my teen years, I could not agree more. Training in free diving techniques is extremely important. Look at the book, but also take a course.
Now, about buddy free diving. Be sure that the buddy has the capability to rescue you. You and your buddy need to be at equal skill levels.
