ONO Boeki Co., Ltd. (Headquarters: Akasaka, Minato-ku, Tokyo) announces the limited-time special pricing of the high-performance chronograph 'ACETECH AC5000' during Amazon's '5th Smile SALE'. As the official Japanese distributor for ACETECH, a Taiwan-based precision instrument manufacturer serving the airsoft industry, ONO Boeki introduces this advanced chronograph at a value-driven price point.

"Is my gun really within regulation limits?" "What if it's disqualified during field measurement?" "I'm not sure about the accuracy of cheaper chronographs" – these are common concerns among airsoft players regarding muzzle velocity management. The ACETECH AC5000 addresses these worries with high-precision numerical verification powered by IR sensor technology and self-calibration functionality.

~ From "Probably Fine" to "Confidence Backed by Numbers" ~

Being told your airsoft gun exceeds velocity limits during a field check – this frustrating moment is one every player wants to avoid.

Muzzle velocity can fluctuate due to various factors such as temperature, battery charge level, and component aging. "It's been a while since my last measurement – is it still okay?" "My chronograph reading differs from the field's, leading to disqualification" – this vague sense of "probably fine" often leads to problems on the field.

The ACETECH AC5000 supports consistent measurement accuracy through its IR sensor and self-calibration function. With a wide measurement range of 30–400 m/s for muzzle velocity and 100–5,000 rounds per minute for rate of fire, it covers all types of airsoft guns in a single device.

For players who want to verify their gun's performance at home before heading to the field, the AC5000 delivers the peace of mind that comes from numerical confirmation – all at a value-oriented price.

〇 Three Key Reasons Why the ACETECH AC5000 Stands Out

【1】 Maintains Measurement Accuracy – IR Sensor × Self-Calibration Function

The AC5000's greatest strength lies in the combination of high-precision IR sensor measurement and self-calibration functionality. While conventional chronographs may develop measurement inconsistencies over time, the AC5000 actively maintains accuracy through self-calibration. This minimizes discrepancies between your readings and official field chronographs, enabling reliable home-based velocity management. It's a trustworthy device that helps prevent last-minute disqualifications.

【2】 Broad Measurement Range Covers All Types of Airsoft Guns

With a velocity measurement range of 30–400 m/s (displayed to one decimal place) and a rate-of-fire range of 100–5,000 RPM, the AC5000 handles all velocity management needs in one unit. Its ability to record and store data for up to 25 shots adds significant practical value, allowing users to compare multiple measurements over time.

Regular measurements help objectively identify trends such as "velocity has changed since last time" or "how much temperature affects performance," aiding in determining optimal maintenance timing. Developing a habit of pre-field checks significantly reduces the risk of disqualification on game day.

【3】 Reliable Taiwanese Quality × Compact, Field-Ready Design

Measuring 117×97×59mm and weighing 200g (excluding batteries), the lightweight and compact body fits neatly into a small space in your gear bag. Powered by two AA batteries, it allows for easy battery replacement at the field, ensuring operation even in case of unexpected power loss (※ Batteries are sold separately).

ACETECH, headquartered in Taiwan, is a precision instrument manufacturer with a long-standing reputation in the airsoft industry. The AC5000 is manufactured under high-quality standards, offering both reliability for long-term use and an accessible price point – making it an ideal choice for both first-time buyers and experienced players.

〇 Amazon Smile SALE is Now On! The Time to Take Velocity Management Seriously

Move from "probably fine" to "confidence backed by numbers." The high-performance ACETECH AC5000 chronograph, equipped with IR sensor and self-calibration technology, is now available at a limited-time special price.

For all players who want to avoid field issues and enjoy airsoft with peace of mind, we recommend purchasing before the sale ends. The special pricing will conclude when the campaign ends.
