Munzee exists to get you outside and moving! With the creation of virtual fields it is possible to spend hours capturing Munzees with very little movement. In order to get those caps done quickly and get you moving again, we introduce the Blast Capture! The blast capture may be used to capture up to 100 virtual or mystery virtual munzees within one mile radius of your current location. If there are 14 virtual and mystery virtual munzees within one mile radius it will only capture 14. If there are 114 within one mile radius it will only capture 100. This product will not capture any physical munzee or virtual quiz.

The blast capture is simple. Purchase credits here in the store. Confirm they are added to your account at www.munzee.com/credits. Choose a location with plenty of virtuals to be captured. Press the bomb symbol at the bottom left of the screen. Confirm the number of virtuals to be captured, then allow the blast to do the work for you. You will notice the munzees being captured convert to a bomb symbol. There is no need for you to interact with these munzees but you can move on and begin capturing other Munzees. Patience is required while using a blast capture because it will take at least 3 minutes (up to 30 or more minutes during weekends and peak server usage) for all captures to be completed. At completion you will receive a popup message indicating the number captured and the total points.
