I agree with you. I had no part of the tunnel. Builder did it the day following the dive.

brrscuba, Im glad that you got this pool repaired but would be very careful about digging a hole like that. I think that OSHA would have something to
say about not shoring the side walls to prevent cave-ins.

I almost never use my mic. Never really had much luck with it. I sent in my Fischer XLT-30 to get modifyed to work with sensor. Problem was they
didn't have my sensor in hand to make sure everthing matched up. When ever I use my mic. I here a lot of interferance. I'm thinking of sending the
XLT-30 and the mic back to Fischer for a re-cal. You guy's talk so highly about it. I think it would be a good thing for leak's. Keep you updated.

leaky2, thanks. good idea. since i already have a quality pool pole in my van for leaktrac i use plastic friction tape to attach my hydrophone to it.
i am real careful to make sure all is very dry.
Luv the my butt thing. the older i get the fonder i am of mine.

The hydrophone can save your but in cold weather- but I went to Ebay and got a long telescopic fishing pole and zip tied the cord to the pole- it
compacts down to 3' and is very agile in water. I would not mind a second one (not on a pole) just to listen inside plumbing.

Had a pool builder in new jersey call me yesterday. He is building a pool (indoor) in a brand new gym that is opening this friday. he filled the pool
and lost four inches of water overnight. he was convinced it was a light conduit line. Dye testing the returns i noticed they were taking in a lot of
dye being pulled in. I inserted the microphone into each of the returns and found the line leak in one of them. That line was a 90 degree elbow
that extended down vertically. He just called me this morning to tell me the leak was exactly where I told him. No pressure test, no bigfoot sensor.
just the xlt 30 and the microphone. The customer dug up the expensive tile this morning and found the leak. Needless to say, he is getting rid of his
leak detector he has used previously and bringing me on board. He was exceptionally impressed with the electronics, including the microphone. Small
investment proves to have more gains than the intial cost of the microphone. Once again, Just buy one.

I had a pool that had a small leak in the return line that lost a very small amount of pressure over five minutes that could not be heard with the xlt
bigfoot or probe. I inserted the microphone into the pipe and presto, you could hear the leak. i used that measurement of the wire that went into the
pipe and that was accurate enough to find the location of the leak and fix the pipe.

Two years ogo had a brand new pool, broken floor returns, listening with the xlt narrowed it down to two returns??, then removed all the floor return
plugs and inserted the hydrophone down each one, absolute confirmation, the roar of the leak pegged the led readout at 99 and I had to remove the
headphones, the sound was so load that the pool builder could hear the headphone sound while standing on the opposite side of the pool, was able to
pinpiont the leak within 2 inches, next day the builder excavated a tunnel under the pool to get to the leak, see attached tunnel photo, my location
was spot on.

I have used the underwater microphone around skimmer throats on gunite pools where the box meets the plaster (they love to leak there) For the price
its invaluable to me in that you can "sample" areas of the pool for sound. I have used the underwater microphone to actually hear the water rushing
behind the liner. That helped me find the leak. Yes, I still get into the pool to make the repair. Its great hands down.

Rite now I dye test all the pools with an needle and dye what advantage if any would I gain if i bought the hydrophone? I could see using it in the
winter I guess but I would still have to get in to verify.

I was wondering if I could get some advice on the hydrophone ( I have an xlt17) Do they work good? How sensitive are they? 99 percent of the pools I
go to are gunite.
