JAN code: 4950344151837 Manufacturer: Tamiya Model number: 15183 ⚫︎ Box and instruction manual included ⚫︎ Operation confirmed ⚫︎ Box has damage ⚫︎ Mercari delivery Product Description: The "Mini 4WD Grade Up Parts Series" includes the Mini 4WD Speed Checker. This is a measuring device that measures the top speed and running time of your Mini 4WD, and is useful for machine settings and maintenance. Simply select speed check or time attack with the mode switch button, and then place the Mini 4WD with the switch turned on on the speed checker. In speed check mode, the maximum speed is displayed 30 seconds after the start. In time attack mode, you can set the running distance from 10 to 300m in 10m increments with the select button, and measure the running time for each. The speed and time are digitally displayed on a large, easy-to-read LCD display. It can be used with various Mini 4WD cars. Uses 2 AA batteries. It has a safe design that automatically turns off the power in 3 minutes even if you forget to turn off the switch. Simply place the machine on it to measure speed and time. ※ Some currently available Mini 4WD cars may not be able to be measured as is due to interference from bumpers, etc. ⚫️ When listing this item, I confirmed the operation using my child's Mini 4WD, but the lower bumper interfered slightly and I couldn't measure it properly, so I removed the bumper and measured it. I was able to measure it successfully. I think you can measure it without any problems with Mini 4WDs from that time. ⚫️ At that time, I didn't use it much and have kept it until now, so the condition of the main unit and instruction manual is not bad, but the box is badly dented and in poor condition. Please check the photos ② and ③ for a better understanding. ※ Shipping will be via Mercari delivery, with the box and cushioning material placed in a separate cardboard box (I try to ship as soon as possible). ※ Operation confirmed on 2025.10.28 ※ Returns are not accepted to prevent swapping. ※ Immediate purchase is welcome If you have any questions, feel free to comment＾＾
