The GasKnight 2.0 is a compact, portable, and affordable gas detector. The display is bright and easy to read, and the unit's sensitivity is adjustable so you can set it to detect only small amounts of gas, or to detect larger amounts of gas, which is ideal if your home has natural gas lines or you have a gas furnace. The unit has a loud, piercing alarm that alerts you if there's a gas leak in your home. The alarm is also loud enough to be heard in other parts of the house, so you'll know if there's a leak anywhere in your home. The GasKnight 2.0's sensitivity is about average, so you'll generally hear the alarm if you hear natural gas or propane leaking, but you might want to raise it to a setting that detects larger amounts of gas for the highest protection. The display is only black and white, which limits its visibility in low-light conditions. The display also takes up quite a bit of space on the unit, so it's small and might not fit where you need it to. The GasKnight 2.0's battery lasts about 3 years, and it's easy to install, so it's a great choice for many homeowners.
