Yes, it's designed to be able to take a direct hit to the glass (1J point-blank) without braking.

It will hold up to normal use but extremely close, high power shots could still damage it.

Both glass and OLED display are user-replaceable and available as spare parts upon request.

No, hits are counted manually using the buttons. There is no reliable way to detect hits in airsoft automatically.

It is resistant to rain, dust and moisture which makes it suitable for normal airsoft game days.

It is NOT rated to be used under water!

You can use any battery between 3.0V and 13.0V to power the counter.

Here are some ideas on how you can use it:

• AEG users can wire it up to the battery you already use (7.4V / 11.1V LiPo)
• hide a small LiPo battery in grip / stock
• wire up USB cable and use a power bank
• use 3x AA or 3x AAA batteries
• salvage a small LiPo battery from a vape

The kit includes special heat shrinking tubes that connect the wires using only a lighter / blowtorch.

We also provide step-by-step video instructions that make it super easy to follow along.

This is to keep the device as small as possible (true to in-game size) and avoid increased shipping costs.

We also didn't want you to have yet another device to charge and forget before the game.

This way you can wire it up to your AEG battery or any other power source and place it where it's convenient for you.
