I was worried about GPS signal lock times, but this 32-channel module finds satellites in under a minute even with light cloud cover. The cable is a good length for my CEM40 setup.

Jason ★★★★★ Oct 19, 2026

The 32-channel receiver locks onto satellites within seconds every time I power up the mount. Setup was straightforward—just plugged it in and the mount immediately recognized the GPS signal. This module saves me the hassle of manually entering coordinates before each session.

Finally got a solid lock after just a few seconds with my GEM45—much faster than the old module. The 32 channels really make a difference for satellite acquisition in my light-polluted backyard.
