Arizona Unit 4B Mule Deer Hunting Guide
Arizona Unit 4B sits in the north-central portion of the state and draws steady interest from both resident and nonresident hunters chasing mule deer across a mix of pinyon-juniper flats, grassland, and timbered breaks. With 854,984 total acres and 57% public land, Unit 4B offers a legitimate DIY opportunity for hunters willing to put in scouting time before the season. This article breaks down what the data actually shows about harvest trends, herd health, and application logistics for hunters researching Unit 4B mule deer hunting.
Unlike units with sprawling wilderness tracts, Unit 4B is a road-accessible unit with no designated wilderness acreage, which keeps access straightforward for hunters willing to walk off the beaten path. The terrain ranges from 4,787 to 7,683 feet in elevation, spanning everything from open grassland flats to pinyon-juniper hillsides and pine-timbered drainages in the southern portion of the unit. That elevation spread and habitat diversity is worth understanding before hunters commit points or cash to an application.
HuntPilot Analysis
Is Unit 4B worth applying for? The honest answer depends heavily on what a hunter is looking for. Harvest success in recent years has run in the mid-20s percentage range — 27% in 2025, 26% in 2023, and 22% in 2022 — which is respectable for a mule deer unit with majority-public land access but not a slam-dunk unit where tag holders should expect an easy season. These numbers reflect unit-wide totals across all hunt types, so individual hunt codes may perform differently.
The buck:doe ratio, averaged at 52:100 across five surveys from 2022-2025, sits within a normal range for a healthy but not exceptional mule deer herd. It's not an eye-popping number, but it's also not a red flag — it suggests a stable population without the volatility seen in units with small survey samples producing inflated ratios. The average of only 21 animals observed per survey is a modest sample size, so hunters should treat this as a general trend indicator rather than a precise herd census.
Trophy history for the counties overlapping Unit 4B is limited, meaning hunters should not expect this to be a unit known for producing record-book bucks. That doesn't mean quality deer aren't out there — forum accounts describe hunters finding good bucks with enough time glassing the right terrain — but the data doesn't support marketing this as a trophy destination. Hunters chasing a genuine record-class buck should look elsewhere or treat any big buck taken here as a bonus rather than an expectation.
Tag quotas have also been trending downward. The largest hunt type in the unit (hunt code 1005) dropped from 314 tags in both 2023 and 2024 down to 280 tags in 2025 — an 11% cut. A smaller hunt type (1801) saw a similar proportional cut, dropping from 11 tags to 10. These reductions suggest Arizona Game and Fish is managing herd pressure conservatively, which could mean tighter draw odds moving forward even though this article won't speculate on specific draw percentages — hunters should check HuntPilot's Arizona unit pages for current data.
Bottom line: Unit 4B is a reasonable option for hunters who value opportunity, majority-public access, and a straightforward road-accessible unit over trophy potential. It's not a bucket-list trophy unit, but it's a workable unit for hunters building Arizona points or looking for a solid DIY mule deer experience.
Harvest Success Rates
Unit 4B's harvest data over the last several seasons shows a gradual improvement trend, though success rates remain moderate:
- 2025: 243 hunters, 65 harvested, 27% success
- 2023: 280 hunters, 72 harvested, 26% success
- 2022: 279 hunters, 60 harvested, 22% success
These figures represent unit-wide totals across all hunt types rather than a single hunt code, so actual success will vary depending on which specific hunt a tag holder draws. The upward trend from 22% in 2022 to 27% in 2025 is worth noting, though the hunter count also dropped from 279-280 hunters in 2022-2023 down to 243 in 2025 — fewer hunters afield can itself contribute to a higher per-capita success rate. Hunters should view this as a moderately productive unit rather than one with breakout success numbers.
Trophy Quality
Trophy potential in Unit 4B is limited based on available record-book data. The counties overlapping this unit have a limited history of trophy-class entries, which means hunters should calibrate expectations accordingly — this is not a unit with a track record of producing exceptional bucks. Forum accounts from hunters who've drawn tags here echo this: good, mature bucks are attainable for hunters willing to glass extensively and cover ground, but Unit 4B has not established itself as a go-to trophy destination in the way some other Arizona units have.
Hunters focused primarily on antler size may want to weigh this limited trophy history against the unit's other strengths — namely accessibility and moderate success rates — before investing points here specifically for a trophy hunt.
Herd Health & Population Trends
The wildlife survey data for Unit 4B, drawn from four survey years between 2022 and 2025, shows an average buck:doe ratio of 52:100 across five surveys. This ratio falls within a normal, sustainable range for mule deer herds and doesn't show signs of the extreme swings that typically indicate unreliable small-sample surveys. However, the average of only 21 animals observed per survey is a relatively small sample size, so hunters should treat this ratio as directionally useful rather than statistically precise.
Without multiple years of ratio-by-ratio breakdown in the data, the safest conclusion is that Unit 4B supports a stable mule deer population that isn't showing dramatic decline or dramatic surplus of bucks relative to does. This aligns with a unit that produces moderate, consistent harvest success rather than boom-or-bust results.
Access & Terrain
Unit 4B spans elevations from 4,787 to 7,683 feet, giving hunters a range of habitat types to work with depending on where in the unit they focus their efforts. The terrain transitions from open grassland and flats in the north to pinyon-juniper cover in the central and southern reaches, with tall pine timber and drainage systems described in the unit's southern portion. This diversity means hunters can adjust strategy — glassing wide-open country for deer moving through flats, or working timbered draws where deer bed during the day.
With 854,984 total acres and 57% public land, the majority of Unit 4B is accessible to public hunters, though a significant portion (43%) remains private. Hunters should use mapping tools to identify public parcels before scouting, particularly since water availability can vary significantly by season — monsoon rainfall patterns affect how many stock tanks and natural water sources hold water throughout the unit, particularly in the southern portion. In drier years, hunters may need to concentrate near reliable water sources to find deer activity.
There is no designated wilderness acreage in Unit 4B (0%), which means road access is generally good throughout the unit and hunters aren't dealing with pack-in-only terrain restrictions. This makes the unit approachable for hunters using vehicles to cover ground and access glassing points, though some areas will still require hiking to get away from pressure. HuntPilot's mapping tools, including public land overlays, can help hunters identify specific access points and public parcels within the unit boundary before the season.
How to Apply
For 2026, Arizona Unit 4B mule deer applications follow the state's standard deer draw calendar.
Note that Arizona requires hunters to hold a qualifying license before they can apply for the draw — this license fee is separate from and in addition to the application fee and point fee.
Tag quotas for specific hunt types in Unit 4B have trended downward recently. Hunt code 1005 dropped from 314 tags in 2023 and 2024 to 280 tags in 2025 (an 11% reduction), while hunt code 1801 dropped from 11 tags to 10 tags over the same period (a 9% reduction). These cuts suggest hunters should not assume tag availability will hold steady year over year.

Frequently Asked Questions
What is the terrain like in Arizona Unit 4B? Unit 4B features elevations ranging from 4,787 to 7,683 feet, with terrain that transitions from open grassland and flats in the northern reaches to pinyon-juniper hillsides in the central unit and pine timber with drainages in the southern portion. There is no designated wilderness in the unit, and road access is generally good, making it approachable for hunters covering ground by vehicle before hiking in to glass or still-hunt.
What is harvest success like in Unit 4B for mule deer? Recent harvest success has ranged from 22% to 27%. In 2025, 243 hunters harvested 65 deer for a 27% success rate; in 2023, 280 hunters harvested 72 deer for 26% success; and in 2022, 279 hunters harvested 60 deer for 22% success. These are unit-wide figures across all hunt types, so success will vary by specific hunt code drawn.
How big are the mule deer in Unit 4B? Trophy potential in Unit 4B is limited based on available record data — the counties overlapping this unit have a limited history of trophy-class entries. Hunters can find quality, mature bucks with dedicated scouting and glassing effort, but this unit has not established a strong track record for producing record-book-caliber deer.
Is Unit 4B worth applying for? Unit 4B is a reasonable choice for hunters prioritizing majority-public land access (57%), moderate and improving harvest success rates, and a road-accessible unit without wilderness restrictions. It's less compelling for hunters specifically chasing trophy-class bucks, given the limited trophy history in the surrounding counties. Hunters should also note that tag quotas have been cut in recent years, which may affect future draw competitiveness.
What should hunters know about water sources in Unit 4B? Water availability in Unit 4B is closely tied to seasonal monsoon rainfall. In strong monsoon years, stock tanks throughout the unit — particularly in the southern portion — fill up and spread deer activity across a wider area. In weak monsoon years, some tanks run dry, concentrating deer near the remaining reliable water sources. Hunters scouting ahead of the season should check current water conditions rather than relying on assumptions from previous years.
