• GODIAG BDC3 Adapter Kit Feature: Each probe is fitted with a protective sleeve. If a probe needle bends during use, it can be easily pulled out and replaced. This also allows for quick replacement if the needle is damaged during shipping. The sleeve improves durability and greatly lowers the risk of breakage.
• Equipped with an adjustment screw. If clamping pressure is too high, users can adjust the screw to reduce pressure on the probe.
• Built-in DIY connection interface enables flexible connection according to users’ existing equipment, supporting compatibility with other devices in the future. The Autel-compatible adapter includes silicone soldering wire, allowing users to solder various key types or read/write chips as required.
