- Radar or camera?
- Radar units (Garmin R10, Mevo+, Rapsodo) sit a few feet behind you and track the ball in flight, so they need room behind the ball and some flight distance in front. Camera units (SkyTrak, Launch Pro, Foresight, Garmin R50) sit beside the ball and read it at impact, so they work in a shorter room and indoors with a net right in front. If your room is shallow, choose a camera unit.
- Do I need a projector?
- No. Every launch monitor shows its numbers on a phone, tablet, PC or its own screen. A projector only matters if you want a life-size course on an impact screen. A TV beside the net is the cheaper middle step.
- Net or impact screen?
- A net stops the ball and costs less; you watch the shot on a screen beside it. An impact screen stops the ball and shows the projected picture, so you watch the ball fly into the course. Screens need an enclosure to catch misses.
- Can I use it in a cold garage in winter?
- Usually, with care. Check the manufacturer's operating temperature for the unit, keep the battery warm between sessions, and give a cold unit time to warm up before you turn it on so condensation does not form inside. A frozen mat is hard on the joints, so let the garage warm a little first.
- Do I need a subscription?
- The basic numbers never need one. Simulator courses often do: some units include the first year, some charge yearly, some include courses outright. Each product page on this site has a row that says which.
