Cobra 4138 (Thatcham Cat 1 Approved)

The best made Thatcham Cat 1 in history. One of the Leading Cat 1 alarms in the EU due to the ease of programming and quality. The difference between the 4138 and the 4138HF is the HF includes the microwave sensor over the standard ultrasonics which is great for a convertible where you need to leave the roof down in the summer. The Microwave sensor is also good for classic vehicles meaning no pillars or headlining have to be disturbed due to the microwave sensor sitting under the centre console. The 4138 comes fully loaded with all the regular features and the super strong Cobra remote controls like most of the G series.
