underwater inspection

[cazzascotta]

Hello,
have anyone ever used a video camera like this video camera ?
if so, how do they perform in terms of hull or propeller inspection? Have any idea about using this with my laptop monitor instead of its own monitor?
thanks
Antonello

I was interested in doing this to look at mooring chain etc.
The video output from the camera is usually composite video, so you will need some sort of video input adaptor to capture this analogue signal onto a laptop. Something like Win-TV perhaps.
You mayalso need lots of lights or clear water!

Maplin do one
They do work but if you want to see detail you need to mount it on a pole of some kind to get it close and keep it still. I think our Maplin camera, N77FX was about 50 quid on special offer a whilo ago. Really handy for looking at the propeller.

I have an underwater digital camera and have used it to look at the boat on the river mooring.

The clarity of the water is critical as is the light level. An underwater torch is easy to add to adress the light level though. Having said all that the images were usable to diagnose the fault after a bit of adjustment on the pc.

How did you use it? On the end of a pole? How did you press the shutter? or did you set it on video, or swim with it?

I have a digital camera with underwater housing, but have previously dived in scuba gear to take piccies.

If you had it on the end of a pole (or a flat surface like an oar blade) then couldn't you just set the self-timer.

I use all sorts of underwater video kit for survey work, some of it very shiney and expensive kit. I was working on a small boat last year when we broke the umbilical cable on the £10k kit - I got out my Maplins £50 B/W camera and finished of the survey with that. The results were suprisingly good.

I investigated a bit further into the spec of the kit and realised that the video chip inside some of these cheap cameras were identical to those in the very expensive kit.

I would always recommend a colour camera if you can stretch to it.

A top tip is to gaffer tape a cheap dive torch (£8 in Maplins) to the camera housing if its a bit dark or shadowy where you are working.

PM me if you want any more info.

Maplin do a black and white one, I bought one last year and it does as it says on the tin.

I bought the Maplin one at £55 to check my shaft anodes etc ,does a great job even on a dimmly lit day , others have used in the marina and are also impressed , just attach the camera on your boat hook with some cable ties and off you go .
