Researchers have examined diving habits and behavior around Eilat’s natural and artificial reefs. According to study, the average diver density at the artificial reef was higher than at the two nearby natural knolls, and the Tamar reef effectively diverts divers from natural knolls. Secondly, the study found that regarding attitudes toward natural versus artificial reefs, divers consider the artificial reefs more appropriate for training, but they feel less relaxed around them.
