Flushable Sonde

[GroundScope]

Anybody used one of these, I got a Prototek FT8 512hz disposable sonde, works great but not prepared to loose it so tied a traceable string on it & pulled it back up. Supposed to be a throw away item when battery goes dead - anyone tried cutting it open & replacing battery ??

Ive never used one but from reading Protek's website they give you $5 the next one you purchase if you recycle the dead one back to them..

Which to me sounds like all they do is put a new case and battery on it..

For $32, Id probably just leave it in the sewage...

Cool idea though.. it would stop at a blockage allowing you to locate it. Not as good for locating the line (unless you can locate as fast as the water and sonde travel through the pipe..)

Forget $32, they are $80 here, I tie mine on with Electric fence string, Direct connect TX to string & locate away , Pull it back out & your good to go .
One idea I have yet to try is steel Model Airplane control line wire spooled onto a fishing reel !!

sure, they work great. use some 150# test braided nylon and a reel. you can make a capstan if you reel out enough wire and have a lot of running h2o, like in an ag irrigation supply line.
