The TST 507 is the best Tire Pressure Monitoring System (TPMS) on the market, and the only one that includes a color monitor. The cap sensor is very popular for those that are looking for a low-profile sensor. This is the hybrid Cap Sensor which means that it is a sealed sensor and can be submerged into water making it popular for marine use. In addition, because the sensors are sealed, you cannot change the batteries in the sensors, but the sensor comes with a 3-4 year battery in them. Once the battery depletes then you throw the sensor away and buy a new sensor. These Hybrid sensors can be used with metal or rubber valve stems. Note: These sensors do not come with anti-theft device.
