Floating key rings

When tested they were very unsuccessful. MBY tests never saw most of them bring things up at all and would not publish a report in the mag. There is an invitation to the maker to submit revised models for tests.
 
I have bought 72 Waterbuoy key rings. Should be here in the next few weeks.

When they arrive I will conduct a test with whatever material you specify. (No, not gold!)

Maybe the forum can let me know, what to use.

At least then we can put this to rest..... or maybe stuck to the bottom /forums/images/graemlins/frown.gif

Any idea why they failed?
Have you bean given inside information?
 
U think the firing mechanism was the problem but then if they added anything like the weight they claim to lift in say the form of steel they would also never come back - so its one of two reasons. The first is that the mechanism did not fire, the second that someone tried a one kilo steel bar /forums/images/graemlins/smile.gif
 
I would really like you to do this test.

Using a steel/iron metal weight of say 700 grams (not even the kilo claimed)drop the device into water of greater than 10 foot depth. If you never see it again then just lower the weight to say 400 grams. If you never see that one again then try sending them back under the trade descriptions act

I don't think it's the weight that's so much the problem I think it's the WAIT!!! From what I read in the tests they did eventually work - after about 1/2 an hour - way too long. So when you test them see how long they take - don't use too heavy a weight.
 
Ignore Gludy /forums/images/graemlins/grin.gif ( sorry Paul /forums/images/graemlins/smile.gif )his way means you'll lose loads of them
Start with a low weight ( say , one key ) and as others have said , give it plenty of time to work ( timed ) then increase by one key at a time until it can't lift it ( don't forget to weigh each time /forums/images/graemlins/blush.gif )
 
If these are the things I think they are, you can only use them once anyway, so even if you get it back it's no use again. With Gludy's method, all you've lost is a few bits of scrap metal. Not so sure about trying it with increasing numbers of keys, though. Just as you're getting confident - Hey, this is good! /forums/images/graemlins/grin.gif- the next one stays down with half a dozen keys /forums/images/graemlins/shocked.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif and you can't start the boat or car, locked out of the house . . .

Gludy, stop trolling. I thought we had this discussion before and we agreed they would work fine? /forums/images/graemlins/grin.gif

Next you'll start talking about specific gravity /forums/images/graemlins/grin.gif /forums/images/graemlins/wink.gif
 
Whoops /forums/images/graemlins/blush.gif

Good point /forums/images/graemlins/grin.gif

Scrap my last , don't use keys /forums/images/graemlins/grin.gif whoops again /forums/images/graemlins/blush.gif too late /forums/images/graemlins/laugh.gif
 
As soon as they arrive I will try it.

One should do it with increasing weight each time

May be at Portishead Marina with witnesses. Sometime in approx 2 weeks

Thats if they will allow it in the Marina.... DAMO what do you think?
 
Just so you are aware.
It ism claimed that the lifting power is one kilo of steel weight.
It was claimed that the weight used on the TV was about 2.6 kg but of lower density than steel.

One test in shallow water would be to test the 1 kilo claim - but as suggested above use a fishing line because I do not think you will ever see the weight again without it.

The longer the delay for the trigger the worse the lifting power - so a delay of secinds will reduce the lifting power a lot - this is because the greater water pressure at depth redcing the size of the balloon and hence the lift.

Why have you bought so many?
 
I bought so many to sell them, through our online shop. Need to pay for the boat somehow.

I understand the issue with depth etc.

Also, trying a lighter weight to start with and then increase it. I have thought on the fishing line idea, but only if it has neutral buoyancy etc.

It will be interesting
 
Just 5lb fishing nylon which is very thin will more than do the job.
Do not forget, you waste them each time you use them - they are a throw away after use cadget
So gradually increasing weight sounds expensive! /forums/images/graemlins/smile.gif
