Description

Hemisferium Nocturnal and Tide computerThis piece is a replica of a Nocturnal and Tidal Abacus from 1570, signed by Humphrey Cole, an English maker of scientific instruments and engraver. Currently, this instrument can be found in the British Museum, London. One of its faces is a Tidal Abacus and the other is a Nocturnal. The Nocturnal was used to keep time at night. By observing the stars, it was noted that certain boreal constellations rotated around the Pole Star as if a giant clock

Good Tool
Size: One Size, Style: Bottle Opener
This thing is great at opening bottles, and it has a Klein handle. Perfect for the electrician in your life, even if that's yourself. I had to knock off a star because the handle is not quite as good as other Klein tools. The plastic is not as clear. The TIP-IDENT bottlecap marking is off-center and not fully printed. The bottle opener sticks out at a slight angle. This does not affect the performance, but it does detract from the novelty somewhat.

Great light for hard hat.
Style: 180 Lumens
These lights are perfect for our crew. They mount easily over a hard hat. Our guys are tough on them throwing them in the truck or down on the Jobsite. Very durable and offer good lighting for individual worker. Batteries will last a whole shift.

Great Helmet Light
Style: 250 Lumens
Fantastic illumination which is what I need when I’m walking under ground in train tracks area the tunnels aren’t very well lit. This gives me added lighting along with my flashlight to make me feel safe plus help me watch my step.

Good light. Minor flaws.
Style: 180 Lumens
Good light, only flaws is that it didn't come in a box. It was just in a clear plastic bag. And batteries were not included.
