I would strongly recommend you find yourself a fishing buddy for your first few nightfishing sessions, not only does this increase your personal security, but provided you are both organised and work well together, it will reduce the potential problems of playing, landing and unhooking by torchlight.
It is far easier to concentrate on playing a fish in the dark (especially if there are snags present) if you can be confident in a friend to illuminate the water for you if necessary, and to net the fish for you. It is also easier to avoid dosing off with company on the bank. Co-ordination of baiting and casting will make you both more efficient and reduce disturbance to the swim. Fish one rod each and share the costs of hook/ ground bait, torch batteries, snacks etc.
Also should you catch the whopper of your dreams you will be able to get that all important snapshot quickly and therefore release the fish asap to fight another day.
