Did a two day Accelerated Deco course with Mark as course lead instructor & instructor for my group. Very knowledgeable and shares from his experience across different diving agencies & lines of work, I appreciated the direct but fair style of teaching. Would definitely recommend.

5* all the way! Had a fantastic 4 days diving from the scavenger. Mark and crew always on hand to help, or with a hot drink and mini rolls after a dive. I even managed to rip my drysuit wrist seal on the first day so accepted I may be out of action for a few days, but Mark was amazing and found me a drysuit to use so I didn't miss a single dive! Highly recommend and will definitely be back again next year!

I recently had some really great Twin-set (and B&T) training with Mark at Vobster Quay. Twin-sets are his bread and butter. He lives and breathes diving. I went away feeling safe and confident to progress on my Twin-set. And look forward to booking future events to progress further. I can’t recommend Mark highly enough!

Mark is an exceptional diving instructor. I have done a few courses (BSAC, TDI) with him and each has been worthwhile, they are well led, enjoyable, but most of all they have developed my ability and confidence in the water. A couple of months ago I transitioned to sidemount diving and I feel that I am now a competent and safer diver thanks to Marks thorough guidance. See you soon 😃

Having just completed another course with Mark Lewis this past weekend it was another enjoyable and memorable experience, with lots of valuable learning experiences thrown in. It is always a pleasure to train, dive and explore new diving and mountaineering locations with Mark from the wrecks of Scapa Flow to the mountains of the Lake District along with exploring the bottom of Red Tarn 718m above sea level.
