May not work with 2-stroke engines

I have found nothing wrong with the physical quality of the tachometer. However, I couldn't calibrate it for the 150hp Mercury 2-stroke outboard I bought it for. None of the adjustment ranges provide correct readings compared to a diagnostic speedometer. ATTENTION, if this product does not work in your application, there is no point in returning it. When I asked to send it back they gave me a shipping label that requires postage to be paid. The shipping costs from the USA to China exceed the value of the goods. When I contacted the seller, he told me to send him a video of the non-working product before refunding. Much luck. To update. The manufacturer finally agreed to provide a 50% loan without having to return the goods. I appreciate this gesture.

Pros
