On the Road or on Your Wrist With so many available compatible Garmin devices, you can keep an eye on your dogs wherever you go. Pair with fēnix® series watches for tracking from the wrist while you’re on foot. Or pair with the rugged Tread® off-road powersport navigator, the Garmin DriveTrack™ 71 car navigator or a Montana® 700 Series handheld (each sold separately) to track from the road. Compatible with the Garmin Explore™ App Garmin Explore is now compatible with your PRO 550 handheld, allowing you to track up to 3 dogs and see their locations in real time on your compatible mobile device. You can record and store each hunt in its own collection, which is saved automatically to the cloud for easy access when you need it. You can view and play back individual dog tracks on your phone or other smart device. And customizable tracking lines let you assign line colors for each dog, based on speed threshold — so you can clearly see when a dog starts the chase.
