How we score

Same criteria and weights for every device: containment and the 3-year cost count most, and static correction never earns points.

$1,150 over three years

$1,149.98 once: no plan to pay for.

Great if…

  • you hunt or train in the field, far from cell towers
  • you run several dogs (up to 20 on one handheld)
  • you want a replaceable collar battery and rugged hardware

Skip it if…

  • you want to keep a dog in the yard: it has no automatic containment
  • you want to use your phone instead of a handheld
  • your budget is under $1,000

What living with it looks like

The handheld shows each dog on a map, with updates as often as every 2.5 seconds, over radio rather than cellular. Tone, vibration and 18 levels of stimulation are sent by hand from the handheld; nothing happens on its own at a line.

Garmin states up to 68 hours for the collar in dynamic mode (25 hours at 2.5-second updates) and up to 55 hours for the handheld. The collar weighs 262.7 g with its strap and is rated 1 ATM; the handheld is IPX7.

The catch

The price is two products: the Alpha 300 handheld ($799.99) and the TT 25 collar ($349.99). Extra collars are $349.99 each.

The warranty is not stated on the product pages we read, so it is left out of the score.

The verdict

The Garmin Alpha 300 with a TT 25 collar is a hunting and field-training system, not a backyard fence: VHF radio tracking up to 9 miles, no cell service, no plan, up to 20 dogs on one handheld. It scores 7.7/10 on our backyard-oriented formula, mostly because it has no automatic boundary and costs $1,149.98 up front.

Garmin Alpha 300 + TT 25 gets 7.7/10 (fair) with our overall weights, from a raw weighted average of 4.6/10. Left out because no figure is stated or the criterion does not apply: fits small dogs, smallest yard, warranty. The scales are on the methodology page.
