Product details

LeakTronics research and development team has taken the advanced listening capability of the Pool Scope and turned it on its edge – literally. Meet the Yellow Head SM-1 Side Mic.

The SM-1 Side Mic takes control of the direction where the phantom-powered diode listens and pushes its range uni-directionally. Now, listening on vertical surfaces put the focus directly in front of the mic head and extends its range further behind pool walls and into pipes that run away from the pool. The design reduces ambient noise and distraction from behind the user to aid in listening for leaks with extreme accuracy. When listening along pool walls to lights and skimmer throats, along tile lines and cold joints, structural cracks or in return fittings, the SM-1 offers precision detection with the same comfortable control as the Pool Scope. In spas, with limited room to move but multiple points of entry, getting direct listening on each specific jet fitting is easy with the controlled uni-directional focus of the SM-1. It’s a perfect addition to any swimming pool leak detection kit.

Uni-directional listening offers an added benefit when listening to trunk lines and spa pipes behind shared spa/pool walls, or simply through the shell. When pipes are pressurized and pushing water, or air and water out of a crack, the noise it makes is detectible with the uni-directional focus applied from the SM-1.

The SM-1 is designed alongside the rest of LeakTronics Yellow Head hydrophones, with superior build quality and listening capability. The standard build length is 20 feet on Yellow Head hydrophones and the cables offer an industrial grade sheathing and wire-winding that can withstand daily and repetitive industrial and commercial use for years. For identifying the smallest leaks, or other seemingly unidentifiable water flow in higher volume pools and water vessels with larger footprints and more added features, the Yellow Head Series of hydrophones touches all bases and provides faster and more precise leak detection results.

Yellow Head hydrophones can be made to custom cable lengths. Waterparks and resort level swimming pools and spas often demand greater capabilities, and LeakTronics can meet those demands. We’ve customized cable lengths on reels for customers at literally hundreds of yards while providing the same consistent results that find leaks fast and let customers get to repairs. Call or contact us for details on custom builds and making hydrophones to meet your needs.

The SM-1 is the perfect addition to the Pro Complete Leak Detection Kit, the VILO Leak Detection Kit, the Pro Kit or any of the kits that include use the LT-1000 Amplifier.
