TerraLUX Tactical 3 flashlight
One of the most useful devices to have onboard your boat is a reliable and powerful flashlight, and the Tactical 3 from TerraLUX is most certainly both. Moreover, it is waterproof to around 8 feet for up to 4 hours, has a tempered-glass lens, and is constructed with hard-anodized aluminum for durability. The Tactical 3 has three different settings—at the highest (which blasts 250 lumens) it can run for 1½ hours and at the lowest it can run for 130 hours. The unit measures 6.4 inches in length and runs on two AA batteries.
