1 Based on volumetric testing at a known fixed depth. True depth accuracy depends on factors such as ground composition, utility characteristics and the locate frequency / signal strength employed. Always follow local safe digging guidelines.
2 The RD7200 will locate to greater depths in the right conditions, but depth accuracy will be compromised. Depth measurement will not be displayed beyond these depths.
3 Water projected by a nozzle at a pressure of 30kPa /0.3 bar / 4.4 psi in accordance with BS EN 60529 1992 A2 2013.
4 At very low temperatures, battery life will be degraded and measurement precision may be reduced.

Transmitter Enhancements
| Current Direction (CD) |
Provides current direction (CD) signals to enable the locator to differentiate individual utilities. |
| iLOC remote control |
iLOC is an advanced Bluetooth® link between the RD8200 locator and transmitter, which allows you to control the locate signal’s power and frequency from up to 450m away. Less time walking and more time locating. |
| SideStep® (Tx-10B only) |
Shifts the locate and transmitter frequency by several Hz, out of the bandwidth of other locate signals that may be interfering with the locate. |
| SideStepauto™ |
Automatically selects the best frequency to use based on the load impedance (works only in direct connect mode). |
| Fault Find |
Enables the use of an accessory A-Frame with a compatible locator to detect and pinpoint pipe’s coating and insulation faults and cable’s sheath fault. |
| Boost |
Sets the transmitters to output its maximum output power indefinitely or for a predefined period of time. |
| Maximum Voltage Selection |
Allows the user to increase the voltage, and the current, output to a maximum of 90 Vrms. |
| Ingress Protection |
IP65 – Shock resistant, ingress protected casing protects against knocks, drops, water and dust. |
| Lithium Ion battery pack option |
Deliver extended run-time, lighter weight and superior cold-weather performance by comparison to standard alkaline batteries.
No need for operators to replace, manage and recycle alkaline battery cells, reducing the associated costs, workload and environmental burden. |
| Automatic impedance matching |
Transmit your locate signal as far as possible by automatically matching the transmitter impedance to that of your target cable. |
| Eco Mode |
Automatically reduces the output power to allow full depletion of the alkaline batteries. An audio and visual warning provides user feedback (only available with alkaline batteries). |
| Power Selector |
Restricts the power output of the transmitter to a predefined level. |
| Automatic overvoltage protection system |
In the event of an erroneous direct connection to a high voltage line (up to 250V), a warning symbol is displayed advising the operator to take action. |
