Snorkeling day trip - Amazing trip. Great snorkeling experience. Beautiful views and great knowledgeable crew on board. Very friendly. Food was, very fresh. Snorkeling was easy, safe and fun. I would highly recommend this activity. Thank you crew!

Great day on the reef - Had 3 great dives on one day. All crew were very friendly. The whole operation felt professional and safety was clearly a top priority.

Highly recommend for a fun fun fun day - What a fantastic day out. It was everything and more exceeded our expectations. Great knowledgeable crew, friendly, fun and most importantly the safety talks were very clear and precise which lead us to feel very comfortable. Food was amazing and loads of it, very fresh and such a suprise The snorkeling was easy, safe and the best fun . I would highly recommend this activity, you won’t be disappointed Thanks crew and captain Sharky

A great day at the reef - This was a great trip. The crew were attentive, the food was great and the sealife was amazing. Definitely worth a visit.

Great for both SCUBA and Snorkel!! - TL;DR: Great for both SCUBA and Snorkel (also have "crash course SCUBA"). Three dive sites w/min down town between. Great dive guides! State of the art dive equipment. Closed heel fins. Bring your own towel. Good food w/veg option and beer for sale. Certified Advanced Eco Tourism. Would 100% book again! I highly recommend the Poseidon Snorkel & Dive Cruise! My husband and I are SCUBA certified, but our friends are not and like to snorkel. This was the best cruise to accommodate both SCUBA and Snorkel. We did 3 dive sites at the Agincourt Ribbon Reefs which were amazing! They broke down the SCUBA groups into 3 major groups; Experienced, Novice, and "Crash Course SCUBA". I am a novice and my husband is experienced, but they put him in my group so we could be buddies. Kevin, our dive guide, was great. He knew I was a novice so he checked on me often during the first dive, then talking with him after he did less "check-in's" the remaining 2 dives, since he knew I felt comfortable. I overheard some of the training for the "crash course SCUBA" class and it was all good material to refresh myself on (since I just got certified and I learned units in imperial). This would be a good option for someone who is comfortable in the water and wants to SCUBA, but does not want a certification. The food on board was great and offered vegetarian options. There was beer for sale which was great for the ride back. The boat is large enough to bring a small bag with towel and change of clothes, which I recommend for the ride back. They provided Lycra suits for SCUBA and snorkel since it was "stinger" season. I brought my own mask since I felt most comfortable with it. The gear was exactly what I trained on with separate secondary regulator. They pack your BCD with an extra snorkel and inflatable signal tube. They do provide closed heel fins, so if you are between sizes on fins you should bring your own dive socks to be more comfortable. On the ride back you can order pictures/USB they took along the way and had them ready before we left the boat. All in all a great day!

Emma and Steve are the funny ones ..... - Great team. Friendly and humorous. The whole experience was fantastic. I would recommend thus to anyone wanting to dive on the reef.

Wonderful experience, highly recommend. - I had a great day, I was picked up by Cam am taken to the Port Douglas Marina. It was windy day and a rough ride on the boat but once on the reef and under the water it was amazing. We did three dives under Dive Master Gordon on the Poseidon through Quicksilver. The colour changing cuttlefish who stayed about for 5 minutes was a diving highlight. We had the opportunity to see sharks and the usual fish that live on the reef. The food was lovely along with the staff. I was placed on a different bus in the afternoon which had a fault light come on. This was not a problem Cam was driving another bus behind us and picked us up and we were on our way within 10 minutes.

Unforgettable diving experience! One tick off bucket list! - The whole experience exdeeded my expectation. Staff was very friendly needless to mention the outstanding service. Diving equipment looked new and well maintained. There was a marine scientist to give us a talk between dives,which I appreciated a lot. We had three dives on the day. There wasn't much time in between because the agenda was quite packed. However, the arrangement was smooth, just be noted to have your lunch swiftly (not recommended to be so full when diving anyway) We met moray fish, lion fish, a lot of fishes etc. It looked like a huge aquarium in real life! One tick off my bucket list. Don't hesitate if you are thinking to join this tour. . . Let's peserve our ocean together because its so beautiful and utterly important to all living things :)

Great experience - Would highly recommend this. It’s an amazing privileged experience. Good boat. Good gear and very exciting sites. I did a scuba initiation dive which was fantastic. Guide was very helpful and guided me very well. Thanks for that. Whereas most of the crew was very helpful and extremely friendly. One or two were very patronising and unfriendly which dramatically downgraded the experience. A point for this company to work on.

Certified Diver Horrendous Experience - Be Forewarned! - Certified Diver (PADI) review only. I had booked a total of 6 dives separated over 2 days, December 5th and 7th departing from Port Douglas. To summarize I was completely shocked with the lack of professionalism, rudeness and extremely poor customer service offered by several boat staff including Scuba Professionals Dive Masters. Both days were on a mixed Snorkel/Scuba Tour Boats: Dive Day #1 SuperSonic, Dive Day #2 Poseidon Outer Reef. I will now proceed to provide backup details to justify my negative review. Whilst the the balance of evidence is not quite sufficient to submit a PADI Serious Incident Report it's only by the thinnest of margins - I witnessed 2 safety incidents. I was directly involved in the second incident which could have resulted in the death of a fellow scuba diver. In my estimation there was a lack of co-ordination between the Diver Master and Dive Coordinator which directly resulted in 2 unsafe water entries. In the second incident in which I was directly involved the Diver Master intimidated and rushed this smaller group of 6 divers comprised of a Dive Master, 4 paying certified divers plus one employee diver on a pleasure dive. We were harried during suit up and rushed into the water for the commencement of diving - this was a significant contributing factor to what potentially could have been a scuba diving fatality. When I challenged the staff on the safety issues upon my return to the boat I was berated and humiliated to the extent that I cancelled my 3rd dive on December 7th - I was in complete shock at what I witnessed. Incidentally the Dive package cost $400/day for 3 separate dives - I was refunded $15.22 for cancelling my last dive? Full disclosure I am a novice Diver aged 60 - which I was at pains to point out during the initial dive briefings. Other less serious issues I observed but nonetheless very aggravating.... 1. Underwater Photography...there is a cameraman who escorts on certain dives. In one instance at ~10m depth I was waiting to get a picture of me with a cuttlefish - as I attempted to move into photo position the Dive Master photo bombed the shot - which she laughingly later admitted at surface. On the second day we had a smaller group of 4 paying dive customers The photographer did not take any photos of me. 2. Buddy System - Diving is a buddy sport but when everyone is wearing the same black Lycra rental stinger suit it's really easy to lose your buddy which just adds to confusion at depth. Add in a couple of groups of 8 people mixing underwater and its chaos. I recommended that we all have paired colour coded identifiable armbands but this was waived off by the experts in charge. 3. Time Wasting - On the first day a Pro level paying customer was using his own equipment, he was paired as my buddy he had his own equipment so he was identifiable. He was the last diver scheduled to enter the water - as he was about to enter the water he realized he forgot his weights - then he had problems with his tank, etc. The water was a little choppy so I was using the regulator - and was consuming air at surface. Hence total bottom time was reduced accordingly. If the Dive Master had any decency or respect to the folks already in the water she should have informed Pro guy to postpone his dive. The Pro guy was assigned to me as my buddy - a complete mismatch in skills - he delighted to chart his own course - at least he was identifiable albeit at a lengthy distance, absolutely useless in case of an emergency. 4. Insulting Behaviour - I received my PADI certification in Thailand - it was directly expressed by the Dive Master on the second day that Thailand is an unsafe country in which to dive - effectively inferring I was an unsafe diver? When the review book came around at the end of the second day - the Dive Master from the first day said "well I guess we wont ask Kenny for a review today.....hahaha" this was in front of other paying customers resulting in more humiliation for me. 5. General Assistance - There was a lack of any helpful support - i.e helping with Stinger suit removal ( they are thin Lycra suits) staff would watch me struggle with my suit removal and fin removal...with folded arms without extending a common courtesy of assistance. This was a bucket list trip for me travelling from Canada via Thailand to visit the GBR for what would potentially be the first and possibly the last time - let me end by saying this will definitely be my last trip to the GBR on a mixed snorkel/scuba tour. From my standpoint the behaviour of the staff has reflected poorly on my impression of Australia. I do have electronic copies of fully completed dive logs - No incidents were reported on either day.
