Just got back from Lanzarote, did two days of diving with Safari Divers (would have done more diving but with group of non divers on holiday!). Plus and minus points really! Diving was fab - massive groupers, angel shark, cuttlefish, usual small stuff. Dive sites included the Cathedral and Blue Hole. Safari Divers seem to attract a lot of Dutch and German clients, with the minority being English. First dive, the guide was buddying up with me but did not do a buddy check - when I reminded him of this, he said "I know what your gear does"!. Second dive on second day, my buddy who was instructor level seemed to wander off just when I had a bit of trouble. On a positive note, the diving was fantastic, Safari also lent me a mask when I had trouble with mine. But would def try another dive operation when I go back. You live and learn!
