If you work on cars for a living or as a "shade tree mechanic", there are certain things that are REALLY difficult to diagnose without the right tools. One of them is a refrigerant leak. If you have an air conditioner that you constantly need to charge with refrigerant, you're wasting money every time you charge it without repairing it. This is the tool you need to detect a leak and pinpoint its source. It has a bright, bright display, is relatively easy to use, and has a built-in rechargeable battery. If you can find a reason to diagnose or fix leaks in your HVAC system, you NEED it.
