TEC Accessories TEC-S311M (Black Diamond)
The TEC-S311M Isotope Fob is a keychain fob specifically designed to hold a standard 3mm x 11mm self-luminous tritium vial. Tritium vials come in a variety of colors, and will glow for many years without requiring any type of "charging" from sunlight. This version of Isotope fob is very similar to our longer TEC-S323 and TEC-S360 fobs, however it is simply shorter in length. This allows you to attach the Isotope to smaller objects such as a keychain flashlight without interfering with its use. And since the vials are short, you get the added benefit of a lower cost compared to our full-length Isotope models. It's the perfect way to color-coordinate your items in a cost-effective manner!
NOTE: THIS PRODUCT DOES NOT INCLUDE A COLORED TRITIUM VIAL. Tritium vials are available here (size required is 3mm x 11mm).
Unlike our conventional line of glow fobs, the Isotope was designed around the use of a glass tritium vial. This makes it noticeably smaller than our standard glow fobs, and allows it to glow continuously without any type of charging cycle! The Isotope is a stainless steel housing, bead blasted to a uniform matte finish. There are 3 slots on each side of the housing to provide maximum tritium visibility, yet offers superior protection of the glass vial. Once the tritium is installed, you simply insert the included rubber plug (spares included) and attach the top split ring. This prevents the tritium vial from sliding out, yet provides an easy way to exchange vials if you want a different color.
Attach the TEC-S311M to any item you wish to identify in the dark. You can clip it to a backpack, a flashlight, a pocket tool, the uses are endless!
