"I set out to complete the Open Water Diver Course with my 12 year old son, discovered DivinDec and the rest as they say is history. Declan and his instructor Justin, brought us through from the basic skills to the final open water dive with patient expertise. The equipment and standard of tuition was first rate, and we progressed quickly under their expert guidance. I was impressed how much my son and I learnt and we both felt a real sense of achievement at the end. I have no hesitation in recommending DivinDec to anyone and to any age. I’m sure we will be back for more."
Lawrence Breen (Dublin)

"Undertaking technical training is not just a question of learning skills, it's more about learning an attitude and approach. You certainly need an instructor who can teach the skills, but that's not enough without instilling the right mindset. The approach Dec takes is detailed, meticulous, and puts tec skills into a real world technical diving context.
He has a very friendly and calm manner, but doesn't let that stop him clearly highlighting where and when standards have fallen short. This is where Dec's teaching approach comes into it's own in identifying weakness and correcting it in a way that provides a permanent reminder and solution.
Dec is first and foremost a passionate and very knowledgable technical diver. Dec uses this experience to bring a richness to his teaching. I cannot endorse his abilities as an instructor highly enough.
I sincerely enjoyed being taught tec diving by Dec and believe I have gained not just a great mentor but also a diving friend. "

"I have just recently completed the Tec 40 course with "DivinDec" in Letterkenny. Having spent the last 12 years diving with many different instructors and diving organisations, I can speak from my experience and highly recommend Declan as professional, knowledgeable and competent instructor. Declan has got a natural teaching style which helps create a comfortable, non pressurised and relaxing learning environment. Highly Recommended. "
Alan Phillips, Dublin

"As a recreational dive instructor with 4 years experience I thought I knew a lot about diving. That was until I met Diving Dec. Three months "tech" diving with Declan taught me more than my previous 4 yrs working as an instructor"
BJ O'Doherty, Thailand - PADI Instructor # 489783

"Declan delivers a well structured and challenging course all in the backdrop of some top class dive sites. Highly recommended."
Cathal Mullane, Limerick - Instructor

"Of all the dive courses I have done and all the instructors I have trained with and english not being my first language Declan's time and patience was immense, I would have no hesitation in recommending Declan for anyone who is thinking of doing any recreational or technical courses."
Vadimas Vadloko, Lithuania and NOT Russia

"What struck me most about Declan was his dedication to providing the best course with no compromise on equipment or of his time even if it was at his own expense. The tec 40 course was the first of many I will undertake with DivinDec."
Lochlann Saunders, Dublin

-----------------------

"After competing the DSAT TEC 40 course with Declan I could not recommend him higher as an instructor. The course was one of the most challenging things I have ever done. I think doing it in the more challenging cold water environment of the Atlantic Ocean was a great decision instead of going to a warm water location. It gave us the confidence and the perpetration to carry out shut downs and other skills in the gear configuration and conditions that we do most of our dives in.
The one thing about Declan as an instructor that really stood out to me was his integrity and his professionalism. Working in an industry where some instructors could be accused of fast tracking students through their courses and sighing them off before they are ready due to economic reasons, Declan could not have been more of the opposite. If the skill was not performed to not only the course requirements but to Declan's satisfaction it was repeated and repeated until it became second nature and if necessary we would do another dive to re-complete the skills. If we completed the skills for that dive without any hesitation Declan would then throw new simulated complications and watch how we dealt with them. It was one of the most worth while courses that I have ever done and thanks to Declan for progressing my diving skills to new level."
Chris Byrne, Carlow

"What can I say about DivinDec other than brilliant. Declan put me at total ease in the water and brought me from being a novice to Rescue Diver in only four months. He is a fabulous instructor who will put you through your paces, as well as provide invaluable information that will have you prepared for any situation. As for the equipment DivinDec uses, it's second to none, giving you the opportunity to try different makes and models enabling you to find the right setup for comfort, fit and familiarity etc... Highly recommended, I will continue to train and dive with DivinDec for a long time to come."
