NICE EZY COMPACT TACH METER FOR MY GAS PLANE COMES WITH Y CABLE AS TO CONNECT TO CGI IGNITION SYSTEMBit inaccurate at idle speeds, seems to bounce around a lot. Hasn't stopped me buying 4 of them. they are very good for tuning up multi gas engine installs. Easier than using a single tacho, tuning one engine at a time.Used this during the running in period of my NHG gf38. Great for tuning the engine.More accurate than a infrared tachometer as it gets the signals from the cdi hall sensor. In most CDIs I used the Y lead is not necesary as they have a dedicated rpm sensor lead.Untested as yet. I will add a review when I have used it in anger.Ein Freun von mir hat ihn und ist zufriedenOne works great and one works for 2 Month the it was showing wrong datagood product, I advice for itIt is very usefuul and you can make a scale cockpitworks perfectly on my dle 35 ra
