FAQ
Prices for gps & gnss systems in Pakistan move with the exchange rate, so we quote by WhatsApp on the day rather than publish a figure that is wrong by the weekend. Send the model or the job and Shahzad Brothers replies with a current price, availability in Rawalpindi and delivery time to your city, usually within the hour during business hours.
The current range includes Sokkia GRX1 GNSS Receiver, Sokkia SHC250 Field Controller, Kolida K6 GNSS RTK Receiver and 13 more. Everything is listed on this page with its model and specification, and we source models that are not listed on request.
Yes. Shahzad Brothers delivers nationwide from Rawalpindi, typically in 2 to 3 working days to Lahore, Peshawar, Karachi, Multan, Faisalabad and most other cities. Larger machinery goes by dedicated transport and we quote the freight with the price.
New equipment carries a 2 year warranty honoured in Rawalpindi, not overseas. Service, calibration and spares are handled on our own bench, which is why most of our customers are repeat buyers: contractors, consultants, universities and government departments supplied since 2002.
