Underwater camera and sonar device

[coyotezh]

We have all kinds of underwater camera available these days, why we still need sonar devices? What's the advantages of a sonar fish finder?

Anyone used Aqua-Vu® AV Micro 5c Underwater Camera?

Flashers can be used in low light and at night.
Flashers can be used in deep water.
Flashers do not hang deep in the water scaring some fish away.
Flashers are way more portable for covering ground.
Some flashers have GPS, don't think any cameras do yet.

Lots of reasons to own both. There are times when each are invaluable and times when each are useless.

The Micro 5c cameras do look neat and would be nice to have at times. Would be really nice for taking quick looks in a bunch of holes instead of having to lug big camera around.
