Using this OtterBox Pursuits 40 is a breeze. First, decide on the size that suits your project - small, medium, or large. Open the box and place your items inside, like GPS loggers or other wireless components. If you want to carry it around, use the included lanyard. You can also strap it to something using the side slots. When it comes to maintenance, keep it clean by wiping it with a soft cloth. Since it's made of tough material, it's durable but be careful when trying to drill into it as it can be hard. And remember, this box is waterproof, so it can protect your items from water damage in most situations.
