It adds stimulation, vibration and tone alongside the position reporting, so a handler working an Alpha handheld can correct and recall without switching devices. The TT 25 with Tracking Beeper is the same collar with an integrated beeper for upland work, where an audible mark matters as much as a dot on a map. The T 20 is tracking only — in the United States its vibration and tone functions are not available, so it is the right choice when you want location data and beacon lights without correction.\u003c\/p\u003e\u003cp\u003eAll three run a user-replaceable rechargeable lithium-ion pack and charge over USB-C. TT 25 and T 20 ship with the standard pack; the extended pack is sold separately and roughly doubles the stated run time. LED beacon lights are built in and can be switched between colours from the handheld, which is what actually finds a dog at last light. Collar straps up to 1 inch are supported.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Alpha TT 25","offer_id":48499959595229,"sku":"010-02447-20","price":349.99,"currency_code":"USD","in_stock":false},{"title":"Alpha TT 25 and Beeper","offer_id":48499959627997,"sku":"010-03383-20","price":599.99,"currency_code":"USD","in_stock":false},{"title":"Alpha T 20","offer_id":48499959660765,"sku":"010-02447-00","price":299.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/3810\/0851\/files\/cf-xl_e4e43e25-b84f-4990-ba84-1c9fd22827f8.jpg?v=1788476000","url":"https:\/\/divecatalog.com\/products\/garmin-alpha-tt-25-t-20-dog-tracking-training-collar","provider":"DiveCatalog.com","version":"1.0","type":"link"}
