The DT-721 and DT-725 Digital Stroboscope is packed with many of the same features as our
famous DT-300 series stroboscopes, but are lighter in weight.
Constructed of strengthened high impact plastic, these rugged stroboscopes are exceptionally reliable
and withstand the same harsh conditions as more expensive units.
Both stroboscopes are sold separately or as a convenient kit.
The DT-721/DT-725KIT contains a strobe tachometer, extra flash bulb, charger (model DT-725only)
and rugged carrying case.
