Arizona Unit 40B Mule Deer Hunting Guide
Arizona Unit 40B sits in the southwestern corner of the state, covering roughly 2.2 million acres of desert terrain that stretches from near sea level to approximately 4,556 feet in elevation. This vast unit holds 92% public land — an exceptional figure that gives hunters genuine DIY access across most of the huntable landscape. Whether hunters are chasing mule deer through bajada flats or glassing rocky ridgelines in the upper reaches of the unit, the public land footprint here is one of the most attractive features of 40B from a logistical standpoint. This article pulls from data compiled by HuntPilot to give applicants a factual, no-nonsense look at what this unit offers.
Unit 40B's sheer size and low-elevation desert character define what kind of hunt this is. The terrain ranges from open flats and rocky desert foothills in the lower elevations to more broken, rugged country as you gain altitude toward the upper end of the unit's range. With no designated wilderness within the unit boundaries, hunters are not subject to any guide requirements as nonresidents — a meaningful point for DIY hunters who want to work this country on their own terms. Access across the unit is generally road-influenced given the low wilderness percentage, though the desert environment demands preparation for heat, water management, and long glassing sessions typical of low-desert deer hunting in Arizona.
Harvest Success Rates
The harvest data for Unit 40B over the last four years tells an honest and somewhat volatile story. Understanding that variance is critical before hunters invest application points into this draw.
Four-Year Summary (2022–2025):
| Year | Hunters | Harvested | Success Rate | |------|---------|-----------|--------------| | 2022 | 47 | 9 | 19% | | 2023 | 48 | 18 | 38% | | 2024 | 44 | 21 | 48% | | 2025 | 32 | 9 | 28% |
The unit's success rates have swung significantly from year to year. The high-water mark came in 2024, when 48% of hunters filled their tags — a strong number for any limited-entry desert deer unit. The following year, 2025, dropped sharply to 28% with only 9 of 32 hunters connecting. The 2022 low of 19% rounds out a picture of real variability.
A few things stand out in this data. First, hunter numbers have declined from a high of 48 in 2023 down to just 32 in 2025 — likely reflecting tag quota adjustments rather than loss of interest. Second, the 2024 performance was a genuine outlier on the upside. Third, even in the best years, more than half of hunters don't punch their tag. Hunters considering Unit 40B should enter with realistic expectations: this is not an easy hunt with high-confidence harvest odds every year. The four-year average success rate sits in the low-to-mid 30s percentage-wise, which is consistent with the difficulty of desert deer hunting in the southwestern Arizona lowlands.
The drop in hunters between 2023 and 2025 is worth watching. If the unit is drawing fewer tags, competition for deer within the unit may actually improve for those who do draw — but hunters should consult current draw data on the HuntPilot Arizona page to understand current tag availability and applicant pressure before making application decisions.
Trophy Quality
The counties overlapping Unit 40B have a limited history of producing trophy-class deer. Hunters should approach this unit with honest expectations on trophy potential: this is not among Arizona's premier trophy-producing regions, and hunters targeting record-book caliber animals would be better served researching units with stronger trophy track records. That said, desert mule deer in any low-elevation Arizona unit can surprise — exceptional individual animals do turn up — but based on available trophy history, hunters should treat 40B as an opportunity-oriented hunt rather than a trophy-first destination.
Herd Health & Population Trends
No formal wildlife survey data (bull:buck ratios, population estimates, or trend indices) was available in the structured data for Unit 40B. Hunters wanting a detailed picture of current herd health should consult Arizona Game and Fish Department deer management reports directly, or check the HuntPilot Arizona unit page for any survey data that may be available for this unit. The harvest data itself — with the notable dip in 2025 success rates after a strong 2024 — may reflect normal population fluctuation or localized conditions following precipitation and forage cycles, both of which are critical drivers of deer density and movement in low-desert habitats.
Access & Terrain
Unit 40B's 92% public land base is a major asset. For a unit of this size — over 2.2 million acres — that translates to an enormous amount of legally accessible ground. DIY hunters can realistically plan a self-guided hunt across most of the unit without needing to secure landowner permission or worry about hitting private property in every drainage.
The elevation gradient from 80 to 4,556 feet across the unit creates distinct habitat zones. Lower desert terrain dominated by saguaro, palo verde, and desert scrub transitions to rocky hillsides and canyon systems as elevation increases. Glassing is the primary hunting method in this type of country — hunters who can cover ground with quality optics from elevated vantage points will have a significant advantage over those who rely on close-cover still hunting. Desert water sources become critical focal points during warm periods, and scouting for active tanks and natural water in the weeks leading up to a hunt can dramatically increase contact rates.
With no wilderness designation within the unit, there are no guide requirements for nonresident hunters in 40B. Arizona does not impose the same nonresident wilderness guide mandates found in Wyoming — nonresidents can legally hunt all of Unit 40B on a DIY basis. This makes 40B one of the more accessible self-guided options in the Arizona draw system for out-of-state hunters who prefer to run their own operation.
The vast size of the unit also means hunters need to invest real scouting time or use digital mapping tools to identify the specific drainages, ridgelines, and water sources that hold deer within a given season. Spreading effort too thin across 2.2 million acres without a focused plan is one of the most common pitfalls in a unit this large.
HuntPilot Analysis: Is Unit 40B Worth Applying For?
Unit 40B has genuine strengths and clear limitations. Here's an honest breakdown:
Arguments for applying:
- 92% public land makes DIY access straightforward by Arizona standards
- No wilderness, no guide requirements — fully accessible to self-guided nonresidents
- A massive land base means lower hunting pressure per acre compared to smaller units
- 2024 posted a 48% success rate — proof that when conditions align, this unit produces
- The draw is more approachable than Arizona's premier trophy units, meaning hunters with moderate point levels may have a realistic shot at drawing
Arguments for caution:
- Year-to-year success rates are volatile (19% in 2022, 28% in 2025)
- Trophy history is limited — this is not a destination unit for hunters chasing record-book deer
- No herd survey data available to confirm population health or trend direction
- The 2025 season showed a meaningful decline in both hunter numbers and harvest — worth monitoring
The bottom line: Unit 40B makes the most sense for hunters who prioritize a genuine DIY public-land experience in a vast, accessible southwestern Arizona desert unit, and who are more focused on the hunting experience than on trophy ceiling. Hunters willing to put in scouting work on a large, low-elevation desert landscape will find real opportunity here. Hunters whose primary goal is a trophy-class buck should look elsewhere in the Arizona draw system.

How to Apply
Arizona uses a hybrid draw system — 20% of tags go to applicants with the highest point totals, while 80% are distributed through a weighted random draw where bonus points increase an applicant's entries. This means that accumulating points improves draw odds meaningfully, but does not guarantee a tag even at high point levels. Hunters should never assume they are "guaranteed" to draw Unit 40B at any specific point level — always check current draw statistics before applying.
2026 Application Dates:

2026 Fee Summary:
| Fee Type | Resident | Nonresident | |----------|----------|-------------| | Application fee | $13 | $15 | | Tag fee (if drawn) | $58 | $315 | | License fee (required to apply) | $37.00 | $160.00 | | Point fee (if not drawn) | $13 | $15 |
Important: Arizona requires hunters to purchase a valid hunting license before submitting their draw application. The license fee is required to apply — it is not optional or contingent on drawing a tag. Residents must have a valid license ($37.00) and nonresidents must have a valid license ($160.00) in place prior to application. Factor the license cost into the total upfront investment when planning your application budget.
If a hunter does not draw, the point fee ($13 resident / $15 nonresident) is charged to maintain bonus point accumulation for future draws.
Dates and fees are subject to change. Always verify current application details at the Arizona Game and Fish Department website before applying.
Frequently Asked Questions
What is the terrain like in Arizona Unit 40B?
Unit 40B covers over 2.2 million acres of southwestern Arizona desert ranging from approximately 80 feet to 4,556 feet in elevation. The lower reaches are classic Sonoran desert — open flats, rocky bajadas, saguaro-studded hillsides, and scattered canyon systems. As elevation increases, the terrain becomes more rugged with broken ridgelines and more vegetative cover. It is a glassing-oriented unit where hunters who can identify water sources and work vantage points efficiently will have the most success.
What is the harvest success rate in Arizona Unit 40B?
Success rates in Unit 40B have varied significantly over the past four years. In 2022, 19% of hunters harvested a deer. That figure climbed to 38% in 2023, peaked at 48% in 2024, then dropped to 28% in 2025. The four-year average reflects a unit that can produce solid harvests in good years but carries real uncertainty from season to season. Hunters should plan for a challenging hunt rather than expecting high-percentage outcomes.
How big are the deer in Arizona Unit 40B?
Based on available trophy history, the counties overlapping Unit 40B have a limited record of producing trophy-class deer. Hunters should approach this unit with realistic trophy expectations. This is not among Arizona's top-tier trophy units, and hunters whose primary goal is a record-book buck will find better options elsewhere in the Arizona draw system. That said, desert mule deer in low-elevation habitats can occasionally surprise — exceptional animals are always possible.
Is Unit 40B worth applying for in the Arizona deer draw?
Unit 40B is worth applying for if hunters prioritize DIY public-land access, a large and relatively uncrowded landscape, and a hunt that is more approachable in the draw than Arizona's most coveted trophy units. With 92% public land and no wilderness restrictions, it offers genuine self-guided access for both residents and nonresidents. However, hunters focused primarily on trophy quality or looking for consistent high-success-rate outcomes should research other Arizona units more carefully before committing application points. Visit the HuntPilot Arizona page to compare current draw difficulty and unit performance side by side.
Do nonresidents need a guide to hunt Unit 40B?
No. Arizona does not require nonresidents to hire a licensed guide in order to hunt Unit 40B. There is no designated wilderness within the unit, and Arizona's regulations do not impose a general nonresident guide mandate. Nonresidents can legally and practically run a fully self-guided DIY hunt across the entire unit, which is one of the more appealing features of this draw for out-of-state applicants.
