The “Ferris” Receiver | 512 Hz
The Ferris analog receiver is great for septic tank locating with cast iron or non-metallic lines and tanks, using the FTP-8 flushable transmitter.
But that’s not all. Any 512Hz transmitter from Prototek or other manufacturers will work with this receiver, letting you follow cameras, jetters and power snakes wherever they may lead you.
And it’s easy to afford – just $575, or make it a kit for $836 with 3 FTP-8s and hard case.
