This isn't just a review about a torch...

By John Gordon on 08 Nov. 2012

...but more about Northern Diver the company. I bought a Fusion X2 a few years ago, and it packed up just before our recent diving holiday. I replaced it with a new X3, and after my holiday contacted Northern Diver. I could not find either receipt or warranty, but ND were brilliant, and replaced the switch without question. Thanks Cara and ND team! Superb customer service. And a great torch too.

ultra bright

By Barry Francis on 15 Sep. 2011

Having owned loads of dive gear by ND, I wanted a good back up torch for UK diving and as a main when on holiday. This light is good enough as a main light source for here in the UK, let alone abroad. It has a good strong beam for those dark places you love to look into when on a wreck..... another great ND product!

Excellent Service

By Stephen Thomson on 10 Feb. 2016

Bought this torch some years ago and gave great service until the last time I went diving and while checking out my equipment noticed it was not working. Contacted Cara on service support who could not have been more helpful. Sent the torch back for repair and received it back in less than 48 hours. Amazing service! Couldn't ask for more. Many thanks!

Great main or back-up torch - very impressed

By Tim Prince on 07 Mar. 2017

I bought this torch as a 'back-up' light for a trip to Chuuk Lagoon in December16/January17. I was so impressed with its performance that I ended up using it as my main light for several very deep penetration dives. It is just the right size for a BCD pocket or for a wrist lanyard, and is not heavy, but reassuringly 'chunky'. Very pleased with this purchase and would recommend - its rubber protective casing makes it ideal for a clumsy wreck diver!
