If you're night fishing either with a trolling motor or fan, the best advice I can give you is to keep your eyes moving.
After an hour or two of staring at the bottom, it's very easy to get mesmerized. 90% of the action will be within 10 feet of the boat, so don't worry about having to spot anything a long way out. Just every few minutes, take a look off into the distance to give your eyes a rest.
Pick your shots. If the actionis good, you could have a shot every couple of minutes. If you start off shooting at everything you see (you will, believe me! :D ) by the end of the night, you'll be fit for nothing! In a four hour session, 100 shots is not unusual at all.
The 'Aim Low' thing can't be stressed enough! Seriously. To get your eye in before you go, throw a paper plate out on the lawn & shoot at it from 10-12 feet away (If you can stand on something 2-3' high, all the better)
Don't try & hit the plate!!! Concentrate
on the plate, but try &
MISS it by about 16" low. It's a lot tougher than you think! It goes against everything you know about shooting instinctively! :D
It's also the one time you can pretty much lose your form. Short draw, don't anchor, bend your arms, you'll probably need to do them all at some point! It doesn't take a lot to poke an arrow through a carp.
An 8" length of broom handle in your pocket is really usefull (Minds out of the gutter guys
)
If you get your arrow stuck in the bottom, you can wrap the line around the stick to pull t free, rather than burning or cutting into your hands.
If I think of anything else, I'll post 'em up!
