Leica Geosystems DA220 Signal Transmitter
The DA220 transmitter is intended for use with either the DD120 or DD230 SMART locators.
Design upgrades from the T-100 transmitter include replacement of the four D-type batteries with a single Li-Ion rechargeable battery pack.
The locator is now fitted with a micro-USB port to update software and provide calibration and maintenance support.
Once again the DA220 has an IP67-rated enclosure and an output in connection mode of 1 Watt; there is a 3 Watt version for greater tracing range.
Leica Geosystems was formally Cable Detection.
