Yup I've got the Salvo 10W and it is excellent.
Really well made and very solid. The light is fantastic and will do everything you'll probably ever need it to do for UK dives. I often get comments from other divers as to "what was that you were using?!"
~5hr burn time is great for a whole weekends diving without having to be near 240V to recharge which is a real bonus for remote expeditions.
For me, the whole point of diving is going to see interesting things - you can't see stuff properly unless it's properly illuminated - so this alone justifies the cost of a quality torch! (As if you need a reason!
)
FWIW, My brother has the Halcyon 10W and he's flooded that due to a poor cable connection. The way the Salvo's are made, I doubt you'd flood it even if you cut the cable underwater!
Cheers,
Mark.
