Driver Fitting
Length, loft, head weighting and shaft profile, judged on strike pattern before anybody looks at a carry figure. Indoors this is the club that needs the offset most.

We Fit Indoors. We Also Tell You What Indoors Costs You.
The Willamette Valley hands us roughly four months a year where an outdoor session is worth running. So we built the studio around the bay and spent the dry months measuring how far the bay's answers sit from the grass. That difference is not a secret here. It is printed on a card and it goes home with you.

Offset Card — Spring 2025 Revision
Bay One
| Driver, mid-speed group | Bay reads +4.1 yd |
|---|---|
| Three wood off turf | Bay reads +2.6 yd |
| Six iron | Bay reads +1.9 yd |
| Pitching wedge | Bay reads −0.4 yd |
| Fifty-six degree | Bay reads −1.7 yd |
| Spin, full wedges | Bay reads low |
Figures come from paired sessions: the same golfer, the same ball and the same club hit in the bay
and then on grass within a week. Yours will be re-derived from your own paired block if you come
back for an audit day.
The Argument We Are Having
Nobody's Bay Is Course-True. Ours Is Simply Documented.
Every indoor studio in the country converts a very short look at a golf ball into a full flight prediction. That conversion is a model, and models carry error. The interesting question was never whether our screen matches the golf course — it does not, and neither does anyone else's. The question is whether the shop knows the size and the direction of the gap, and whether they will say it out loud.
01
The Bay Is the Record
Between October and April there is no honest outdoor testing here. Grass is soaked, air is cold and heavy, and a wet range ball behaves like a different piece of equipment. Rather than pretend otherwise, we treat the enclosed bay as the primary instrument: controlled surface, controlled temperature, one ball model, the same lighting every visit.
That control is what makes comparison possible. A fitting in January and a re-check in March happen under conditions we can hold nearly constant, which means the difference you see between them is far more likely to be the club than the weather.
Read the long version →What the bay holds constant
- Surface: one hitting mat spec, replaced on a wear count
- Ball: a single reference model, logged by batch
- Air: 66 to 70°F, no crosswind, no gusts
- Light: fixed, so the camera is never guessing
- Instrument position: marked on the floor, not moved
02
The Grass Is the Audit
From April through September we run Sunday audit blocks on turf. These are not fittings. They are calibration work: a small panel of golfers hits the same clubs they hit in the bay, with the same ball, and both sets of numbers land in the same spreadsheet.
What comes out of that is not a claim that our bay is accurate. It is a table of differences — how much the bay overstates driver carry for a given speed band, where wedge spin under-reads, which club categories translate almost cleanly and which need a correction before you write a yardage on a card.
How the pairing works →What an audit block looks like
- Ten to fourteen golfers across a season
- Same ball model as the bay, straight from the box
- Bay block and turf block inside seven days
- Air conditions logged at the start of every set
- Results pooled by speed band, never by individual
03
Two Instruments That Are Allowed to Disagree
A Doppler unit and a photometric camera are watching different parts of the same event. In an enclosed bay the radar sees only a few feet of travel and has to reason its way outward; the camera reads the strike itself and then reasons about the flight. Where they disagree is not noise to be averaged away — it is information.
We run both in Bay One and we watch the gap. A widening disagreement on a particular club usually means something specific: a mis-read on spin, a strike far off centre, a ball that has picked up moisture. Rather than hide the second screen, we point at it.
Where the two split →Who is better at what
- Ball speed: camera, measured at the strike
- Spin axis: camera, from marked-ball imaging
- Descent and peak: radar, once flight is long enough
- Club path and face: camera, directly
- Carry indoors: neither — both are modelling it

Pick the Club That Is Costing You Shots
Each category has its own decision list and its own way of being fooled indoors. Sessions are booked by club, not by package, because most people arrive with one specific complaint.
Fairway Wood Fitting
A ground club with a small margin for error. Sole shape and length matter more than the headline distance number the screen wants to show you.
Fairway wood details →Hybrid Fitting
Where the long irons stop earning their place. We look at the descent number the bay reports, then correct it before deciding what the club has to do.
Hybrid details →Iron Fitting
Lie, length, shaft weight and set gapping, checked with tape on every face. The set is fitted as a ladder, not as eight separate clubs.
Iron details →Wedge Fitting
Bounce and grind against the turf you actually play, plus a frank conversation about how badly an indoor mat lies to you about a wedge.
Wedge details →Putter Fitting
Length, lie, loft and balance read on a flat indoor surface — the one fitting where the indoor environment is arguably an advantage.

Session Shape
Ninety Minutes, Arranged in Four Blocks
The order is fixed because the order matters. Warm-up numbers are recorded separately from testing numbers, and testing numbers are recorded separately from the confirmation block at the end. Mixing them is how a session quietly produces a wrong answer.
-
Your bag goes on the gauges
Loft, lie, length, swing weight and grip condition on every club we are about to discuss. Roughly a third of the sets that come through here are already out of spec, and knowing that changes what the session is even about.
-
Warm-up, logged but quarantined
The first dozen swings of a wet Eugene morning are not you. They are recorded so we can see the curve, then held out of every average we compute.
-
Testing, one variable at a time
Shaft, then weight, then length, then head. Changing two things at once produces a comfortable feeling and no usable information.
-
Confirmation and the offset card
A final block with the chosen build, plus the correction table that turns the bay's numbers into something you can write on a yardage card.
Sample Session Ledger
90 minutes
| Gauge check on current clubs | 15 min |
|---|---|
| Warm-up block, quarantined | 12 min |
| Baseline with your own club | 10 min |
| Variable testing | 38 min |
| Confirmation block | 10 min |
| Build slip and offset card | 5 min |
Nothing here is billed by the shot. If a category needs a second visit to settle, we say so
rather than forcing a decision in the last ten minutes.
What We Will Not Claim
Four Sentences We Do Not Say Here
01
“This screen is course-accurate.”
It is a model with known error. We publish the error instead.
02
“You picked up eighteen yards.”
Not from one block of swings on one afternoon, you did not.
03
“That head is simply better.”
Better for the strike pattern you produced today. That is the whole claim.
04
“Trust us, we measured it.”
Every sheet leaves with the shot count and the discard count on it.
Who ends up on Chad Drive
- Eugene and Springfield players who cannot test outdoors half the year
- University of Oregon staff and students on a short window between terms
- Corvallis and Albany golfers driving down for a bay slot
- Coastal players from Florence dealing with wind and heavy air
- People who were fitted somewhere else and want a second read on the numbers
The Local Part
Fitting for a Valley That Is Wet Two-Thirds of the Year
Golf here is a cold-turf game for a long stretch. Fairways at Riverridge and Oakway hold in February, run in August, and behave like two different surfaces in the same calendar. A club that was chosen on August rollout is often the wrong club in February, and the difference is not subtle.
That seasonality is baked into how we write a spec. We ask which half of the year you play most, whether you walk or ride, and how often you are hitting off wet grass rather than a dry lie. Then we fit toward the condition you actually meet, not the one that flatters the screen.

Sent Back to Us
Three Notes From the Last Twelve Months
“I had been told twice that my driver was fine. Nate put it on the gauge and it was three quarters of an inch longer than I thought, with a grip that had gone hard. The rebuild cost less than a new head and I stopped losing it right.”
“The offset card was the part I did not expect. Knowing my six iron reads about two yards long in their bay meant my gapping actually held up when I got to Emerald Valley in June.”
“They spent twenty minutes talking me out of a wedge purchase and told me to come back in April for the turf day. That is not a sales pitch I had heard before.”

Why the Bay Is Our Record and the Grass Is Only the Audit
Most studios treat indoor numbers as a compromise. We inverted that, and the reasoning has more to do with repeatability than with weather.
