The 2012 version of the Black Diamond Icon headlamp actually looks quite competitive, Have not been able to find it stocked in New Zealand so can not offer a price, but suspect it would be around $189 if it gets here. It offers 200 lumens which is decent, IPX7 waterproof standard, a red LED to preserve night vision (which could be useful for fishing). Plus the ability to lock the on switch to prevent it from being turned on accidentally.
If it was priced comparably to the Fenix I would probably get it for fishing despite the weaker max beam. But I doubt that would be the case.
