Buying tips

When choosing a leak detection tool, consider the type of leaks you’ll be locating (water, gas, HVAC) and the environment (tight spaces, outdoor). Higher-priced models generally offer more sensitivity and dual-mode detection, while budget options provide adequate performance for basic residential use. Battery life, portability, and ease of readout are also key factors to match your workflow.
