I have been using Geophones to locate underground leaks. It has been acurate about 80% of the time. There are some case where I can not hear any noise at all. I am thinking of purchasing an electronic listening device. Does anyone think it would help and be more acurate or does it perform the same as what I am using. It is an expensive investment so I just want to see what others think.
Thanks

I have an XLT 16, and XLT 20 and also a metrotech HL 400 or 4000... something like that. I like to be sure before I start cutting concrete and digging holes. They all have plused and minuses and will get the job done... but some units have operational features that the others dont. For price and performance, I would say either of the new Fishers will do what you are looking for

Xlt20 is worth every penny over the geophone
