Sim Maintenance: Keep Gear Running for Years

---

You spent $2,500 on a simulator. You use it 4 times a week. You’ve never cleaned the launch monitor lenses. You’ve never rotated the mat. You’ve never checked the impact screen for stretching.

And you’re surprised when your spin numbers start jumping around.

Golf simulator gear is not “set it and forget it.” It’s exercise equipment that lives in your garage. It gets dusty. It gets humid. It gets hit with golf balls 500 times a week. If you don’t maintain it, it degrades. Slowly, then suddenly.

Here’s the maintenance guide nobody else writes. Because nobody else wants to tell you that the reason your SkyTrak+ is misreading is because there’s a fingerprint on the lens.

The 5-Minute Monthly Check (Do This)

Once a month, spend 5 minutes doing this:

1. Wipe the launch monitor lenses with a microfiber cloth (the kind you use for eyeglasses). No liquid. No pressure. Just dust off the lenses. Dust on a camera lens = misreads.

2. Check the impact screen for stretching. Look at the bungee cords. Are they loose? If the screen is sagging, tighten the bungees or replace them ($30).

3. Vacuum the hitting mat. Turf fibers trap rubber tee fragments, grass (if you use real turf), and dust. A vacuum keeps the mat clean and prevents the tee hole from clogging.

4. Check all cable connections. USB-C ports loosen over time. HDMI cables vibrate loose. Power cables get yanked. Push every connection in firmly.

5. Look at the projector image. Is it dimmer than last month? Are the colors shifted? If yes, clean the projector lens and check the lamp hours.

That’s it. Five minutes. Once a month. This prevents 90% of problems.

Launch Monitor Maintenance by Type

Camera-Based (SkyTrak+, Bushnell Launch Pro, Uneekor EYE MINI, EYE XO, Square Golf, Trackman iO)

Camera launch monitors are dust-sensitive. The cameras are looking at a golf ball from 12-18 inches away. A speck of dust on the lens changes what the camera sees.

Weekly:

• Wipe lenses with a dry microfiber cloth
• Check the ball-striking area for debris (rubber tee bits, grass, dust)

Monthly:

• Inspect lenses with a flashlight. Look for fingerprints, smudges, or residue. If you see any, use a lens cleaning solution (the kind for camera lenses — not Windex) and a microfiber cloth.
• Check firmware updates. Most units auto-update, but manually checking ensures you’re on the latest version.
• Clean the unit’s exterior with a dry cloth. Don’t use water or solvents.

Quarterly:

• Run a calibration check. Hit 10 shots with the same club and check if the numbers are consistent. If spin readings vary by more than 300 RPM shot-to-shot with the same club and swing, something’s off. See our calibration guide.

Yearly:

• Deep clean: remove the unit from its mount/stand, clean all surfaces, inspect for wear on the casing, check all ports.
• For ceiling-mounted units (EYE XO, Trackman iO): check the mounting hardware. Vibration from 500+ shots/week can loosen bolts over a year.

Radar-Based (Garmin R10, FlightScope Mevo+, Rapsodo MLM2Pro)

Radar units are less dust-sensitive than cameras but more battery-sensitive.

Weekly:

• Wipe the radar window (the flat panel on the front) with a dry cloth
• Check that the unit is positioned correctly (6-8 feet behind the ball for most units)

Monthly:

• Check battery health. If the unit used to last 5 hours and now lasts 2, the battery is degrading. Most radar units use replaceable batteries ($30-50).
• Clean the charging port with compressed air. Pocket lint and garage dust clog USB-C ports.
• Check firmware updates via the manufacturer’s app

Quarterly:

• Test indoor and outdoor mode. If indoor readings are inconsistent but outdoor readings are fine, the indoor calibration is off.
• Inspect the tripod or stand. Radar units need to be level. A wobbly tripod = inconsistent readings.

Impact Screen Maintenance

Your impact screen takes 500+ golf ball impacts per week. It’s the hardest-working piece of equipment in your sim. Here’s how to make it last.

What Kills Impact Screens

1. Moisture — A damp screen grows mold and weakens the fabric. If your garage is humid, use a dehumidifier.
2. Sunlight — UV rays break down screen material over time. If sunlight hits your screen, install a UV-blocking window film or shade.
3. Over-stretching — Bungee cords stretch. The screen sags. The sag causes the ball to hit the same spot harder (because the screen gives more). That spot wears out. Rotate the screen or tighten the bungees.
4. Wrong balls — Real golf balls are fine on a proper impact screen. But if you’re using a screen rated for foam balls only and hitting real balls, you’ll tear it in months. See our guide to using real golf balls.

Maintenance Schedule

Weekly:

• Brush the screen with a soft-bristle brush to remove ball marks and dust
• Check for loose bungee cords and tighten

Monthly:

• Inspect for tears, holes, or thin spots. Small tears (under 1 inch) can be repaired with screen repair tape ($10). Larger tears mean replacement.
• Check the screen tension. It should be drum-tight. If it’s sagging, tighten all bungees or replace them.

Quarterly:

• Clean the screen with a damp cloth and mild soap. Don’t soak it. Don’t use bleach. Don’t pressure wash it.
• If the screen is reversible, flip it. This doubles the lifespan.

Yearly:

• Assess overall wear. An impact screen used 4x/week typically lasts 2-3 years. If you see significant thinning in the impact zone, budget for a replacement ($150-500 depending on size and quality).

Hitting Mat Maintenance

What Kills Mats

1. Wear in the sweet spot — You hit 90% of your shots from the same spot. That spot compresses. The foam underneath flattens. It starts feeling like concrete.
2. Tee hole damage — Repeatedly inserting and removing tees enlarges the hole. A sloppy tee hole means your tee leans, which affects ball position and launch angle readings.
3. Moisture — Foam mats absorb water. A wet mat never fully dries. It gets heavy, spongy, and starts to smell.

Maintenance Schedule

Weekly:

• Vacuum the mat to remove rubber tee fragments and dust
• Move your hitting position 2-3 inches left or right of the main wear spot

Monthly:

• Rotate the mat 180 degrees. The spot you’ve been hitting from moves to the back. The fresh turf moves to the front. This doubles the mat’s lifespan.
• Check the tee hole. If it’s enlarged, insert a rubber tee plug ($5) to tighten it.

Quarterly:

• Inspect the foam underneath. Press down on the main hitting area. If it feels significantly harder than the edges, the foam is compressed. You can’t fix this — it’s time for a new mat.
• Clean the turf with a brush and mild soap. Don’t soak it.

Yearly:

• Assess overall condition. A quality mat used 4x/week lasts 2-4 years. A budget mat lasts 1-2 years. See our hitting mat guide for replacement options.

Projector Maintenance

Lamp-Based Projectors

Monthly:

• Check the lamp hour count in the projector menu. Under 2,000 hours = fine. Over 3,000 hours = budget for a replacement lamp ($150-300).

Quarterly:

• Clean the projector lens with a microfiber cloth and lens solution
• Check the air filter. Clogged filters cause overheating, which kills lamps faster. Clean or replace the filter ($10-20).

Yearly:

• Replace the air filter
• Check the projector mount. Vibration from 500+ shots/week can loosen the mount over time.

Laser Projectors

Laser projectors need less maintenance than lamp-based units. No lamp to replace. No lamp hour count.

Quarterly:

• Clean the lens
• Check the air filter (yes, laser projectors have fans and filters too)

Yearly:

• Replace the air filter
• Check the mount

Enclosure Maintenance

Carl’s Place / DIY EMT Enclosures

Monthly:

• Check all pipe connections. Vibration loosens them. Tighten any loose joints.
• Check the bungee cords. Replace stretched or broken bungees ($30 for a full set).

Quarterly:

• Inspect the frame for rust (especially in garages). Surface rust can be sanded and painted. Structural rust (flaking, deep pitting) means the pipe needs replacement ($3-5 per stick).
• Check the enclosure corners. The corner connectors are the weakest point. If one is cracked, replace it ($5-10).

Yearly:

• Deep clean the enclosure frame with a damp cloth
• Check all zip ties and replace any that are brittle or broken

Climate Control (The Hidden Maintenance)

Your garage is not climate-controlled. Your gear lives in 40-100°F temperatures with 30-90% humidity. That’s harder on electronics than you think.

If your garage drops below 50°F in winter:

• Let the launch monitor warm up for 15 minutes before use. Cold electronics read differently.
• Consider a space heater or mini-split for the garage. See our heating and cooling guide.

If your garage gets above 90°F in summer:

• Don’t leave the launch monitor in direct sunlight. The casing can warp and internal temps can damage electronics.
• Use a fan to circulate air. Stagnant hot air is worse than moving hot air.

If your garage is humid (above 60%):

• Use a dehumidifier. Moisture kills electronics, grows mold on screens, and corrodes metal frames.
• Keep the launch monitor in a sealed case or bag when not in use.

The Maintenance Cheat Sheet

Task	Frequency	Time
Wipe launch monitor lenses	Weekly	1 min
Vacuum hitting mat	Weekly	2 min
Check impact screen tension	Monthly	2 min
Clean lenses with solution	Monthly	5 min

Bungee cords	$30	$30	Replace (not worth repairing)
Enclosure pipe	$3-5	$3-5	Replace (cheaper than repair)

What Actually Matters

Your golf simulator is not a TV. It’s equipment. Equipment needs maintenance. Spend 5 minutes a month and 30 minutes a year, and your sim will last 2-3x longer than the guy who never cleans his lenses.

The guy on the forum who says “my SkyTrak lasted 6 years”? He cleaned the lenses. The guy who says “my EYE MINI started misreading after 8 months”? He didn’t.

Don’t be the second guy.
