but night collecting/snorkelling is in my experience MUCH more effective for
madtoms and some large darters (eg, Crystallaria, Percina shumardi). The
critical point to remember is to know your site well when you are night
collecting- a misstep can have much more drastic consequences than during
the daytime. The little Petzl or Pelican headlamps are really helpful, and
aren't so powerful as to wipe out your night vision. >>

I am not familiar with Pelican but have a great Petzl with double lenses; one
is less intense and easier on the batteries. Both have adjustable focus. I
also have a cheaper one with a single strap that goes around the temples but
not a top strap to go over the top of the head. I rapidly learned the top
strap makes all the difference in the world for keeping it on top of your
head and not slipping around. Petzl's are expensive but worth it.

I also added a clip on high intensity Winchester flashlight with a red filter
on it. Easy on the night vision are harder for others to see me. (It can
take up to 45 minutes for your night vision to totally return after your eyes
have been exposed to light.)

Which leads me to ask if fish can see red filtered light? Perhaps collecting
with just a red filtered light might be more productive.

Also, the replies to this thread stated that many fish migrate to shallow
water at night to feed and avoid predators. This leads me to think that I
will start setting overnight minnow traps in shallower areas than I normally
