A chum of mine was working for them for quite a few years on S61 and then S92 - an ex mil NVG instructor who wasn't selected to train crews because he wasn't Irish, they wanted to keep it in-house despite not having the experience to do so.
This was over 10 years ago and since then they haven't managed to introduce what is very basic technology by modern standards. I don't know if it is the Irish CG, the IAA or CHC who have dragged their heels but someone has questions to answer sending crews out for night SAR without NVG.
I hope they have them now.
