 NEW eVDS Multifunction Strobe - Flashing or Steady!

This Electronic Visual Distress Signal Device (eVDS or eVDSD) is designed to meet   COLREGS Annex IV (d), and is thus an internationally recognized distress signal when used in the SOS mode.

Use steady mode as a backup light or area light. Turn on the light. If it is not in the mode you want, quickly turn it off/on to change modes.

NEW choices include: Strobe/Steady, Strobe/SOS/Steady, or Strobe Only.

For many years, Tektite Strobes have been renowned for their performance and ruggedness. Our Strobe 3500 XL Expedition sets the bar beyond any other strobe. Designed for the rigors of commercial and scientific diving use, this strobe has superior brightness and durability than our Strobe 300™. The battery housing is computer machined from a solid bar of aircraft aluminum; all new solid-state circuitry and a multifunction, 10-watt LED lamp makes this strobe the MOST RUGGED and shock resistant of any strobe we build, or anyone else makes! No fragile glass strobe tubes to break. This double O-ring sealed strobe will run for 100 hours in flashing mode or 20 hours in steady mode on a fresh set of batteries at an initial flash rate of 120 flashes per minute. It can be seen for miles at night (conditions permitting with a clear lens). Used by scientific divers, military, and fire fighters. Includes, at no additional cost, a cushioned wrist lanyard. Optional colored lenses are available. An Infrared (IR) version is available for approved government and military organizations.
