In answer to your question Pemuteran is nearly all boat diving, the diving in the bay is between 3 & 10 minutes and generally all Macro, Menjangan Island is circa 40 minutes by boat and much more coral and fish life focused. I use Bali Diving Academy
Don’t overlook Candidasa as the dives out to Tepekong, Mimpang are very good along with macro at the Jetty
