Inspection cameras are specialist tools that use a digital camera to help investigate hard to reach areas. These are commonly used by builders, and plumbers to inspect pipes, or by electricians to explore wiring conduits and trunking.
- Choosing the right battery: Cordless (or battery powered) tools have a variety of chemical battery types; Li-ion is the latest technology, prior to that it was Ni-MH and Ni-Cad was the original. The higher the Ah (Ampere hours) the longer the interval between charges; the fewer times you recharge a battery the longer it will last. Some cordless tools can also come without batteries - sometimes referred to as naked, bare units or body only. These tools are supplied without a battery or charger and more often than not without any accessories; as a result they are significantly cheaper in price.
- The length of cable is the key consideration when choosing between tools. Longer accessory cables are available.
