Arizona Unit 43B Mule Deer Hunting Guide

Arizona Unit 43B sits among the desert low country of the state, spanning 550,419 acres from just above sea level up to 2,773 feet in elevation. This desert terrain unit offers hunters a substantial public land base — 91% of the unit is open to public access — making it a legitimate option for do-it-yourself mule deer hunters willing to work rugged, arid country. With no wilderness designation within its boundaries, hunters can access the unit's terrain without the additional logistical hurdles that wilderness areas sometimes impose.

Unit 43B has produced a wide swing in harvest outcomes over the past several seasons, and any hunter considering an application here needs to understand both the opportunity and the volatility baked into recent data. This article breaks down what HuntPilot's data shows for harvest trends, herd composition, tag quotas, and the application process for hunters weighing whether 43B deserves a spot on their Arizona deer application list.

HuntPilot Analysis: Is Unit 43B Worth Applying For?

The honest answer is that Unit 43B is a mixed bag, and the data supports a cautious approach rather than blanket enthusiasm.

On the positive side, public land access is excellent at 91%, giving hunters ample room to roam without needing to negotiate private land access or lease arrangements. The absence of wilderness designation also means hunters can use vehicles and mechanized access more freely across much of the unit's legal public ground, which matters in low-elevation desert terrain where covering distance efficiently is often the difference between finding deer and coming up empty.

However, the harvest numbers tell a story of significant year-to-year inconsistency. Success rates have ranged from a low of 16% in 2022 up to 49% in 2024, then back down to 25% in 2025. That's not a steady trend — it's a unit where outcomes appear heavily influenced by conditions in any given year rather than a predictable, climbing or declining pattern. Hunters should not assume the 49% success rate from 2024 represents the norm; the four-year average sits closer to the 30-35% range when all seasons are weighed together.

The wildlife survey data adds another layer of caution. With only two survey years available (2022-2025) and an average of just 35 animals observed per survey, the sample size here is small. The reported buck:doe ratio of 16:100 is on the low end and, combined with the limited survey sample, should be treated as a rough indicator rather than a precise measure of herd health. Hunters shouldn't read too much into a single ratio number generated from such a small observed population — it points to a herd that may be under some pressure, but the data isn't robust enough to draw firm conclusions about long-term trends.

Tag quotas also tell part of the story. For hunt type 1071, quotas were cut from 500 tags in 2023 down to 450 in 2025 — a 10% reduction. That kind of quota trim generally signals that state biologists are managing for a herd that needs a lighter harvest pressure, which aligns with the modest buck:doe ratio noted above.

Put together, Unit 43B is a unit that rewards hunters looking for solid public-land opportunity and reasonable odds of filling a tag in an average year, but it is not a unit hunters should target purely for trophy potential or as a can't-miss producer. It functions best as an opportunity unit for hunters who value access and want a fair shot at a desert mule deer, rather than a bucket-list trophy destination.

Harvest Success Rates

Unit 43B's harvest data over the last four seasons shows real volatility:

• 2025: 366 hunters, 92 harvested, 25% success
• 2024: 409 hunters, 201 harvested, 49% success
• 2023: 419 hunters, 164 harvested, 39% success
• 2022: 413 hunters, 68 harvested, 16% success

The number of hunters afield has stayed relatively consistent, hovering between roughly 366 and 419 per year, which suggests demand for this unit hasn't changed dramatically. What has changed is the harvest outcome. The jump from 16% success in 2022 to 49% in 2024 — followed by a drop back to 25% in 2025 — indicates that conditions (likely weather, forage, and deer movement patterns from year to year) play an outsized role in whether hunters connect in this unit. Hunters should plan for a realistic expectation somewhere in the 25-40% range rather than banking on repeating the standout 2024 season.

Herd Health & Population Trends

The wildlife survey data available for Unit 43B is limited to two survey years between 2022 and 2025, with an average buck:doe ratio of 16:100 and an average of only 35 animals observed per survey. This is a small sample size, and the ratio itself is on the lower end for mule deer herds generally, which can suggest a herd carrying fewer mature bucks relative to does.

Given the limited number of surveys and low overall animal counts observed, hunters should treat this data as a general signal rather than a precise gauge of population health. The quota reduction from 500 to 450 tags for hunt type 1071 between 2023 and 2025 is consistent with a management approach aimed at easing pressure on the herd, which lines up with a buck:doe ratio that isn't showing strong bull-to-cow — err, buck-to-doe — recovery in the available data.

Access & Terrain

Unit 43B covers 550,419 acres of low desert terrain, with elevations ranging from just 117 feet up to 2,773 feet — some of the lowest elevation big game country found in Arizona's mule deer units. This is classic desert topography: open basins, scattered washes, and low-relief terrain that rewards hunters who can glass long distances and cover ground efficiently.

With 91% of the unit classified as public land, access is a genuine strength here. Hunters have room to explore without the access headaches that plague many private-land-heavy units elsewhere in the West. The unit carries no wilderness designation, meaning there are no additional access restrictions tied to wilderness status — hunters can plan routes using standard public land access without needing special permits or foot/horseback-only travel mandates tied to wilderness boundaries.

That said, desert terrain at this elevation range brings its own logistical demands: water sources are limited, heat can be a serious factor depending on timing, and the wide-open nature of the terrain means deer can be spread thin across large areas. Hunters should use HuntPilot's mapping tools to identify public land boundaries, potential water sources, and access routes before heading into the field, since the low-relief terrain makes long-range glassing and careful route planning especially valuable strategies in a unit like this.

Frequently Asked Questions

What is the terrain like in Unit 43B?

Unit 43B is low-elevation desert country, ranging from 117 to 2,773 feet in elevation across 550,419 acres. Expect open basins, washes, and sparse vegetation typical of Arizona's low desert habitat. The terrain favors hunters who can glass effectively over long distances and are prepared for hot, arid conditions with limited natural water sources.

What is harvest success like in Unit 43B?

Harvest success has varied significantly over the past four seasons, ranging from 16% in 2022 to a high of 49% in 2024, with 2023 at 39% and 2025 at 25%. Hunters should expect a realistic success rate in the 25-40% range in most years rather than assuming the standout 2024 season is typical.

Is Unit 43B worth applying for?

Unit 43B offers strong public land access at 91%, which is a real advantage for DIY hunters, but the harvest data shows inconsistent outcomes year to year and the limited wildlife survey data suggests a herd that may be under some management pressure, reflected in the recent 10% quota cut for hunt type 1071. It's a reasonable option for hunters prioritizing access and general opportunity, but not a unit to target purely for trophy potential based on the data available.

How big are the mule deer in Unit 43B?

Trophy data is not available for this unit. Hunters interested in trophy potential should treat Unit 43B as an opportunity-focused unit based on the harvest and herd data available, rather than assume trophy quality without supporting records.

Do I need a license before I can apply for Unit 43B in Arizona?

Yes. For the 2026 application cycle, both resident and nonresident hunters must hold a qualifying license before applying — $37.00 for residents and $160.00 for nonresidents — in addition to the application fee ($13 resident / $15 nonresident) and applicable point fees.
