Check this thing out; a friend I used to fish with had one for when we went sharking and it is wicked. The paddles can be taken off and used as individual torches and then when you click them back onto the main lantern they recharge. Gives off plenty of light too.
I'd be surprised if you don't get asked to contribute to SA Angler in the near future....that's top notch fishing and reporting. Best thing is you don't make it a secret where you catch them; if it's land based I don't see the harm in letting people know. There's plenty of fish for everyone
