Read the Ball Map Before the Next Ball

The free Ball Map plots catalog hook against length. A grade counts covered corners. Speed Check is where a throw gets a number.

If you do not have a speed or a rev rate yet, start with Speed Check. It measures a local bowling video in the browser. The clip stays on your device. The measurement guide covers early lane speed, full lane average, and rev rate. Then open the Ball Map. That is the default Arsenal Builder.

It answers a different question: do the balls you already own cover different shapes, or are they sitting on the same part of the map? The first ball guide is about fit and coverstock. The Ball Map is where those balls get plotted. Free browser tool Put the balls you own on the map before you shop for another one. Search a model, tap it, and see which corner it lands in.

Open the Ball Map What the axes are Left to right is length. The left label is "Reads early." The right label is "More length." Bottom to top is hook. "Less hook" sits at the bottom. "More hook" sits at the top. A dot comes from the catalog's length, backend, hook, and differential. Rev rate, layout, and last night's oil pattern stay out of that placement.

A ball with no hook rating or no cover type stays off the map. When differential, length, or backend is missing, the catalog fills that value from hook and cover type, and the ball still plots. Those filled in specs land like published ones. The map does not flag them. The header shows a speed and a rev rate. A fresh browser starts at 16.0 mph and 350 rpm.

After a valid speed or rev rate, Speed Check links over with Find my balls . The line above that button says the numbers suggest a ball that fits. What transfers is the speed and rev rate into the header. Placement stays on catalog shape. Four corners, and a grade that counts corners The map is split into four labeled corners: Strong · Early — more hook, reads earlier. Strong · Skid flip — more hook, more length.

Control — less hook, reads earlier. Spare / Plastic — less hook, more length. The grade is how many of those corners contain at least one ball. An empty map shows a dash. One corner is a D. Two is a C. Three is a B. Four is an A. On an empty map the coach starts with Strong · Early, because that corner is first in line when every corner is empty. "All 4 corners covered" means each corner has a ball.

Your average stays in the scorebook. Two balls with different jobs can be a cleaner bag than four balls stacked in one corner. Search, then tap "Find a ball" searches manufacturer and model. The cover chips are All, Solid, Pearl, Hybrid, Urethane, and Plastic. The list shows at most 60 matches. Narrow the search when a ball you know is missing from the first screen. Balls that land in the thin corner sort first.

Inside that group, this week's most wanted list orders the matches when it has real data. That list mixes builder interest, balls already in bags, and tracked game results when that sample exists. An S, A, or B chip can show, with a weekly rank. The "in bags" count is separate: distinct BowlSense users who have that ball in their bag.

When the weekly list has no real signal, those chips and counts stay off the list, and the remaining order is alphabetical. Tap a row to add the ball. Build my bag adds one catalog ball to each empty corner that has one, and it leaves a corner you already filled. When the most wanted list has data, that pick leans toward the list, with hook as the other part of the sort.

When the list is empty, the pick is the highest hook in that corner. Remove anything you do not own. The button is a sketch. If the search misses, "Request this ball" asks for a manufacturer and a model. Year is optional. A year you include has to be 1970 or later. Requested balls get priority in the daily catalog pass.
