Wonder if one or two of these little "getter back" devices attached to it would be up to the task of pulling it back to surface? I have had a couple for a few years but never really thought about using them for my rc boats or even just a hatch. Here is the link for who can't see the video below in internet explorer https://www.youtube.com/watch?v=ks8eWyZKMDo

No I never sank a boat ...yet!! Does watching your brand new MTR on its maiden run drift away with the tide, due to a broken steering servo count? And yes I could not get the damn thing pointed to shore to simply throttle it back in.
Attaching it to the inside of the hatch would only be good if the boat flooded inside or the hatch came off.
If the hull was stuck in the mud and water got inside to set off the float. When the float came up you would only pull the hatch off and up.
If it takes 12 minutes of being under water, why not attach it to the main hull.

Vinny we'll let that count for you...lol Damn on the Maiden the servo went out?Quote:

Supposedly the check valve won't release until it's under the pressure of 10ft water after its been submerged for at least 10 minutes.Quote:

Good suggestion but I've seen some come up missing by being stuck in the mud even with floatation and this device may not have pulled it up out of the mud but it may have shown its exact location so someone could grab some swim gear and retrieve it in just a few minutes if the boat was worth it to the owner. Below is a good example where this may have helped someone locate a boat. Just saying... https://www.youtube.com/watch?v=FCic2BIn_qYQuote:

Finding a sunken item is 99% of the battle. If it's too far down for you, a diver is $50-75/hr possibly plus transport/etc. At the least it would pay for a recovered motor & ESC. A specialist searching silt for a few hours is a lot more expensive. It can't weigh much so maybe just attach it to the rudder boom.
From what I gather, it's just a lidded cylinder with something like baking soda & citric acid (alka seltzer) and a weak check valve. Anyone here could make their own small streamlined "blister" version that gets taped/glued to the top of the hull. Another option is just attaching a ball w/velcro & string that will tear off in a bad crash.
Ping pong ball on same kevlar line taped with scoth tape. The tape isn't water proof and might take a some time to pop off oor it may get pulled off in process of submerging. The ball and line could possibly pose a hazard for oval racing.Quote:

It would probably have to be on a spool of some sort so the ball could get a clean release when the tape let go in order for it to make to the surface. The GetterBack float has the line coiled up inside on a cone shaped spool so it would be difficult for it to tangle up once it is deployed. Below is a good video showing some deep under water releases in different configurations and a good thread explaining it better as well.Quote:

I think you could just get a small cup-shaped base the size of the ball, spool the line inside it, and use water-dissolving tape to hold the ball on the base. You can get that tape at fabric stores or Amazon, it's used to sew inside garments and dissolve during the first wash. You'd just need to replace the tape often due to water spray.
It would look kind of like a squat water tower or star wars shield balls: http://www.theforce.net/swtc/Pix/diagram/kdyfaces1.jpg
I thought about the balls with strings attached but my luck it would tangle up...lol! I said to heck with it and went ahead and took one from my tackle gear and installed it on my Zelos just for the fun of it.
