Gopro for propeller anode inspection?

[fastjedi]

I appreciate an underwater camera would be better but I can't use for mountain biking, motorsport and sailing too

At £100 a basic Gopro looks tempting
- Has a low light setting but no idea if this would be adequate
- Would be working blind but could probably capture enough by waving around?

What would I need to get to the propeller?
- I'm thinking a couple of lengths of 2x1 or Aluminium pole + fittings might be better than a dedicated Gopro pole in seawater
- Approach from stern or side of hull .. perhaps from dinghy?

When I had a strange wobble down below, I strapped the GoPro on the end of the boat hook and randomly pointed it at the prop.
I played it back on my iPhone via Wifi.

If this works....

Perfect, Thank you ... Looks like its a Go(er)pro then

Does wi-fi work underwater? I got an SJcam 4000 wi-fi, for Christmas, a sort of knock off Go-Pro but it is possible to view what the camera is looking at via my iPad mini and iPhone 4. You can also start and stop filming, take stills etc. works well indoors but no idea if it would work from under a boat!!

I don't think the wifi signal will travel through water.. Sjcam still £40 quid saving over the basic GoPro though

The wifi feature didn't work for me last summer. As soon as the go pro was a few cm below the water I lost the pic on my phone. So you have to aim it where you think the prop is.......

Great fun on the end of the boathook just above the waterline, especially as we tacked ;-)

Looked like we were going really fast !

Think the plan would be to record then hook go-pro out and watch the film back using the go-pros wifi to link to a phone.

we were not specifically looking at the prop, but is easy with a pole etc

 

[Alpha22]

Exactly how it worked for me.... the Wifi does not work underwater...... at all!

 

[Jamesuk]

I use a Tough Cam for underwater stuff on the boat - works very well on the end of a mono pod from the dinghy.

How do ypu know you are pointing your gopro towards the propeller?

 

[fireball]

Go GoPro has such a wide angle lens that it's practically impossible not to get the Prop in the shot - the difficulty is the back lighting and getting enough detail to see what you want to see clearly.

The video demo earlier in the thread looked great - but you have to remember that was on a mobo with the shaft fairly near the outboard side of the vessel - I did similar with our 37' sailing boat and Volvo saildrive and it wasn't easy - especially from a tender (we were on a swing mooring) - but it did produce some results.

I can confirm that Wifi doesn't work underwater.

I wouldn't buy a GoPro or similar just to inspect the prop - If that's its primary use then there are wired cameras that will give you a live view - but it's certainly a bonus for a secondary use.

 

[youen]

What is a wired camera?Thanks

 

[fireball]

A wired camera connects back to a computer or display by cable

Who said that?

Have look at this http://youtu.be/49K2hjV9OOY I have made one of these and it works. I have a 50mtr roll of the correct coaxial but unfortunately it's on my boat and I am 5 days after a full knee replacement, can't get to boat for some time, but you can get it on line.
