Sighting Compass Outdoor Baseplate Compass MM INCH Travel Baseplate Ruler Compass Map Liquid Filled Adjustable Declination Magnetic Heading for Navigation, Orienteering and Survival 5 Pack

The small size was appealing and I liked how you could place over a map to get coordinates, but unfortunately it didn't work upon arrival. The arrow would spin very slowly, get stuck at different spots and produce different results when I held it different ways. I compared it to my other compass (a decent quality one I've had for years) and this one was sluggish, sticky and inaccurate.The seller refunded my money and I'll use it to buy a better quality compass.
