This page lists the GNSS chipsets that are used in the Garmin Descent watches.
The Descent watches are primarily dive computers, but they are also suitable for “on the water” activities.
The various models are listed in reverse-chronological order. The release dates are generally from Garmin announcements.
The Descent G2 was released after the fēnix 8, so may use an Airoha or Synaptics GNSS chipset.
