Lim Jia Wei –
I used the GD-NRX during a recent dive trip to Tioman. The display is super clear even in murky water and the depth and tank pressure readings were spot-on. Only thing is, it took me a while to figure out the Bluetooth sync feature.

Solid and reliable gauge so far. The alarms are very helpful but the menu could be a bit more intuitive. Overall very satisfied with the performance underwater.
