For those who are enthusiasts of the Hydra camera car mounts, you can add the Tilta Push-to-Start Engine Button Cover to your vehicle for some additional flair. The red cover is emblazoned with graphic on the iris shutter and the phrase "Pro Gear Within Reach" around the rim. With a 1.18" diameter, the cover fits over many vehicle's push-to-start engine button. The mechanical scalloped iris shutter can be used to prevent access to the button, and opened to reveal the button when you want to start or turn off your car or truck. Made from durable zinc alloy material, the button cover is built to last.
