Three signal-strength indicators — bar graph, numeric LCD, and audible tone — let you locate by sight, sound, or both. Display stays readable in bright sun and low-light trenches. Built-in headphone jack for discreet operation around traffic and noisy sites. Up to 20 hours of typical battery life means a full day of locating with margin. Field-replaceable batteries mean zero charging downtime — swap in seconds and keep working. Weather-resistant construction handles mud, rain, dust, and temperatures from -4°F to 122°F. Lightweight 4.5 lb handheld reduces fatigue on long days. Need read/write RFID data storage, GPS logging, and direct GIS handoff? See the Tempo EML250-ID.
