Arizona Unit 39 Mule Deer Hunting Guide
Arizona Unit 39 sits in the desert lowlands of the state, spanning elevations from just 437 feet to 4,004 feet across nearly 1.24 million acres. For hunters chasing mule deer in a classic Sonoran-style desert landscape, this unit offers a sprawling, mostly public block of ground — 82% public land — with terrain that ranges from valley floors to low mountain ranges. Unit 39 is well known among Arizona deer hunters as part of the desert hunting complex in the southwestern part of the state, and it draws attention from both residents looking to fill a tag and nonresidents building a long-term strategy for desert mule deer.
This article breaks down what the data actually shows for Unit 39 — recent harvest trends, herd survey numbers, application logistics, and an honest read on whether it's worth prioritizing in an application strategy. As always, this analysis is built on the numbers available through HuntPilot rather than guesswork or recycled forum chatter.
HuntPilot Analysis: Is Unit 39 Worth Applying For?
Unit 39 is a mixed bag, and the data supports a measured take rather than a blanket recommendation.
On the positive side, this is a big unit with a large percentage of public land (82%) and zero wilderness acreage, meaning nonresident hunters can access and hunt the unit without any Arizona guide requirement tied to wilderness restrictions. The low-elevation desert terrain (437–4,004 feet) is also relatively accessible compared to steep, high-country mule deer units elsewhere in the West — vehicle-supported scouting and hunting is realistic across much of the unit, though desert conditions bring their own challenges in heat, water availability, and navigating vast, visually repetitive terrain.
The harvest numbers, however, tell a story of real year-to-year volatility. Success rates swung from 40% in 2023 down to 19% in 2025, with hunter numbers holding fairly steady in the 370-450 range across the last four years. That kind of swing — 41% success in 2024 followed by a drop to 19% in 2025 — suggests conditions (drought, forage, or herd fluctuations) are having a significant impact on hunter outcomes from year to year. Hunters should not assume the strong 2023-2024 numbers represent a baseline; recent data points to a tougher, less predictable hunt.
The wildlife survey data reinforces some caution here. Across two survey years (2023-2025), the average buck:doe ratio came in at just 21:100, with an average of only 72 animals observed per survey. A ratio that low is a red flag for herd health and buck availability relative to the doe population — it points to a unit where bucks are a smaller percentage of the visible population than in many other desert units. Combined with the small survey sample size, hunters should treat this as a signal that buck numbers may be limited, rather than clear evidence of a thriving, buck-heavy herd.
Trophy data is not available for this unit in the structured data provided, so no qualitative trophy assessment can be made. Hunters chasing a specific trophy class should not assume this unit produces trophy-caliber bucks based on general desert mule deer reputation alone — without unit-specific record data, that claim can't be supported here.
Bottom line: Unit 39 is a legitimate option for hunters prioritizing public land access and a large hunt area, but the recent success rate volatility and low buck:doe ratio mean this isn't a unit to bank on for a guaranteed fill or a trophy hunt. It's best suited to hunters who value opportunity and acreage over predictable, high-percentage outcomes.
Harvest Success Rates
Unit 39's harvest data over the last four years shows meaningful fluctuation:
- 2025: 369 hunters, 70 harvested — 19% success
- 2024: 397 hunters, 164 harvested — 41% success
- 2023: 446 hunters, 180 harvested — 40% success
- 2022: 418 hunters, 90 harvested — 22% success
The pattern here is a two-year high (2023-2024) sandwiched between two lower-success years (2022 and 2025). Hunter numbers have stayed relatively consistent, ranging from 369 to 446 across the four seasons, which suggests the swings in success are driven more by herd conditions, weather, or deer distribution than by changes in hunting pressure. Hunters planning a season in Unit 39 should treat the 2025 season's 19% success rate as a real possibility rather than an outlier to dismiss, especially given that it's the most recent data point available.
Herd Health & Population Trends
The wildlife survey data available for Unit 39 covers two survey years between 2023 and 2025, showing an average buck:doe ratio of 21:100 and an average of 72 animals observed per survey. Both figures point to caution:
A buck:doe ratio of 21:100 is low relative to healthy mule deer herd benchmarks, indicating fewer bucks per 100 does than hunters would want to see in a unit with strong buck recruitment. Combined with a modest average of 72 animals observed per survey, the sample size itself is small, which limits how much confidence can be placed in any single year's numbers. With only two survey years to compare, there isn't a long-term trend line to lean on — hunters should view this data as an early warning sign on buck availability rather than a definitive verdict on the herd, and should check HuntPilot's unit page for updated survey data as new years are added.
Access & Terrain
Unit 39 covers nearly 1.24 million acres, with 82% of that land classified as public — a strong figure that gives DIY hunters substantial room to roam without needing to negotiate private access. There is no wilderness acreage in this unit (0%), which means there are no Arizona wilderness-related restrictions to navigate and no additional guide requirements tied to wilderness designation.
The elevation range of 437 to 4,004 feet places this unit firmly in low desert country. This is classic Sonoran Desert mule deer habitat — broad valley floors, scattered low mountain ranges, and washes, rather than high-elevation timber or alpine terrain. Hunters accustomed to mountain mule deer hunting should expect a different visual and physical experience here: long-distance glassing across open desert basins, heat management (even in cooler months), and water scarcity are the defining logistical challenges rather than steep climbs or elevation sickness.
Because such a large share of the unit is public, hunters have flexibility in choosing where to focus effort, but the sheer size of the unit (over 1.2 million acres) means pre-season scouting is essential to narrow down productive areas rather than trying to cover the whole unit blind. Hunters can use HuntPilot's public land and terrain overlays to identify accessible blocks and plan scouting routes before the season.
How to Apply
Note that both resident and nonresident applicants must hold a qualifying license before applying — this license fee is separate from and in addition to the application fee and any point fee charged during the process. Nonresidents should budget for the full stack of costs (license, application fee, and point fee) even before knowing if they've drawn a tag, since the tag fee is only charged upon a successful draw.
For the most current draw odds specific to Unit 39, hunters should consult HuntPilot's Arizona state page at /states/az, which tracks year-to-year application data as it's published.

Frequently Asked Questions
What is the terrain like in Arizona Unit 39? Unit 39 is low desert country, with elevations ranging from 437 to 4,004 feet across nearly 1.24 million acres. Expect broad desert valleys, scattered low mountain ranges, and wash systems typical of Sonoran Desert habitat. There is no wilderness acreage in the unit, so access isn't restricted by wilderness designations, and much of the terrain is drivable or accessible without technical mountain skills — though the scale of the unit and desert conditions (heat, limited water) present their own logistical challenges.
What is harvest success like in Unit 39? Harvest success has varied significantly over the last four seasons: 19% in 2025, 41% in 2024, 40% in 2023, and 22% in 2022. Hunter numbers have stayed fairly steady (369-446 hunters per year), so the swings appear tied to herd or environmental conditions rather than pressure. Hunters should plan for the possibility of a tougher season similar to 2025 rather than assuming the stronger 2023-2024 numbers will repeat.
How big are the mule deer in Unit 39? Trophy data is not available for this unit in the structured data reviewed for this article, so no specific trophy quality assessment can be made. Hunters interested in trophy potential should look for unit-specific record-book information before setting expectations.
Is Unit 39 worth applying for? It depends on what a hunter is prioritizing. Unit 39 offers a large public land base (82%) and accessible desert terrain, which makes it appealing for hunters who want plenty of room to scout and hunt without private land conflicts. However, the low average buck:doe ratio (21:100) from recent surveys and the sharp drop in 2025 success rate (19%, down from 41% in 2024) suggest this isn't a unit to count on for a high-probability or trophy-focused hunt. It's a reasonable option for opportunity-focused hunters but not a unit with strong data-backed upside for buck quality right now.
What should hunters know before applying for Unit 39 deer tags? Given the recent volatility in harvest success and the low buck:doe ratio from available survey data, nonresident hunters in particular should weigh the cost of applying against the realistic odds of a productive hunt, and check HuntPilot's Arizona page for updated draw odds before committing points or application fees to this unit.
