Protoek 512 Hz Mini transmitter w/ Drophead

Key Features

• Compact Design

The FM-05’s 5/8-inch width and 1-1/2-inch length (with drophead) make it the smallest transmitter in Prototek’s 512 Hz line, ideal for use in tight spaces like 1-inch pipes and small plumbing systems.

• Range and Performance

Provides up to 7 feet of range in nonmetallic lines and 5 feet in cast iron, ideal for small-scale plumbing applications where space and range are limited but accurate detection is required.

• Swivel Drophead for Tight Navigation

The swivel drophead design allows the FM-05 to pass through tight elbows and P-traps, ensuring smooth operation in complex pipe layouts.

• Battery Efficiency

Powered by 357/A76 button cell batteries, the FM-05 offers a long battery life and is available with a battery caddie and an optional 20-battery kit to ensure uninterrupted operation.

• Durable and Watertight

Despite its small size, the FM-05 is built with a watertight construction, ensuring reliable performance in wet environments. The swivel battery cap further enhances its usability and durability.
