If you are studying for the PE exam, you are almost certainly working full time — and there is a good chance your job involves field work. Whether you are on a construction site, visiting a water treatment plant, inspecting a substation, or surveying a roadway, you need gear that holds up to real conditions. And if you are also trying to squeeze in PE exam study during lunch breaks, commutes, and slow hours on site, the right portable tools make a measurable difference.

This guide covers field gear that serves double duty: items that make your day job more comfortable and efficient, and portable study tools that help you make progress on the PE exam even when you are away from your desk. Everything here has been chosen for durability, practicality, and real-world use — not gimmicks.

For desk-focused study gear (calculators, reference books, ergonomic setups, exam day essentials), see our companion guide: Best Study Gear for FE and PE Exam Prep.

Studying While Working Full Time

The PE exam is fundamentally different from the FE in one important way: every PE candidate is a working professional. You have already passed the FE, accumulated your experience hours, and now you are trying to study 200 to 400 hours while also holding down a demanding engineering job. For many candidates, that job involves site visits, field inspections, construction oversight, or client meetings that keep you away from a desk for large portions of the day.

The engineers who pass the PE on their first attempt tend to share a common habit: they find ways to study in the gaps. Fifteen minutes reviewing flashcards in the truck before a site meeting. A practice problem during a lunch break at the field office. Formula review on the commute home. These fragments add up. But they only work if you have the right tools on you — compact, durable, and ready to go.

The rest of this guide is organized into two categories: gear for your field work itself, and portable study tools that travel well.

Field Notebooks

A weatherproof field notebook is one of those items that once you start using, you will not go back. Rite in the Rain notebooks are the standard for engineers, surveyors, and field scientists who need to take notes in any condition. The paper is treated to shed water, so your notes survive rain, sweat, and spilled coffee. They work with regular ballpoint pens and pencils.

For PE exam study, a field notebook doubles as a formula journal. Write down the formulas and concepts you are struggling with, keep it in your vest pocket or hard hat bag, and review it whenever you have a few idle minutes on site. The act of writing formulas by hand — rather than just reading them — strengthens recall significantly. Research consistently shows that handwriting engages deeper cognitive processing than typing or passive reading.

What to look for:

• Rite in the Rain engineering field books with grid or metric paper
• Pocket-sized (roughly 4.75 by 7.5 inches) so it fits in a cargo pocket or vest
• Hard cover or Polydura cover for durability
• Numbered pages — useful for organizing study notes by topic

Mechanical Pencils for Engineering

A good mechanical pencil is a small investment that pays off every day. If you are sketching site layouts, marking up drawings, or working through practice problems during downtime, a quality drafting pencil writes cleaner, lasts longer, and feels better in your hand than a disposable. Two models stand out for engineering use.

Pentel GraphGear 1000

The Pentel GraphGear 1000 is probably the most popular mechanical pencil among engineers and drafters. It has a full metal body with a knurled grip that does not slip, even with gloves or sweaty hands. The retractable tip protects the lead when it is in your pocket, and the built-in lead hardness indicator on the grip is a nice touch if you switch between lead grades. Available in 0.3mm, 0.5mm, 0.7mm, and 0.9mm — the 0.5mm is the most versatile for both field notes and practice problems.

Rotring 600

The Rotring 600 is the premium option. It is a brass body with a hexagonal barrel that prevents rolling off surfaces — useful on sloped site tables or truck dashboards. The fixed lead sleeve is precise for technical sketching but less pocket-friendly than the GraphGear’s retractable tip, so pair it with a pen case or keep it clipped to a notebook. It is heavier than most mechanical pencils, which some people prefer for long writing sessions because you can let the weight of the pencil do the work.

Portable Whiteboards and Flashcards

Two of the most effective study techniques for the PE exam — active recall and spaced repetition — work best with physical tools you can use anywhere.

Small Portable Whiteboards

A small dry-erase board (roughly 9 by 12 inches) is one of the most underrated study tools for engineering exams. Use it to practice writing formulas from memory, work through multi-step problems, and sketch diagrams without burning through paper. The key advantage is that erasing and rewriting forces you to reconstruct knowledge from scratch each time, which builds far stronger recall than simply re-reading your notes.

Portable whiteboards also simulate the exam experience. On both the FE and PE exams, you get a small whiteboard or note booklet at the testing center for scratch work. If you have practiced on a similar surface, the format will feel familiar on exam day.

Tip: Keep one in your truck or work bag. During downtime — waiting for an inspection, a concrete pour, or a meeting to start — pull it out and drill five formulas from memory. Ten minutes of active recall is worth more than thirty minutes of passive reading.

Index Cards and Flashcard Systems

Physical flashcards are still one of the best tools for memorizing formulas, unit conversions, and key concepts. Buy a pack of blank index cards and create your own — the act of writing the card is itself a study exercise. Organize them by topic using a rubber band or small card box, and carry a stack with you. Review them during any idle time: waiting rooms, lunch breaks, or the passenger seat on the way to a site visit.

If you prefer a digital option, our app includes a built-in flashcard system with spaced repetition that works offline — useful when you are on a job site with no signal.

Hard Hat Accessories

If you spend significant time on construction sites or in the field wearing a hard hat, comfort accessories are not a luxury — they directly affect how much energy you have left for studying at the end of the day. Fatigue from uncomfortable PPE is real, and it compounds over the months-long PE exam study period.

Worth considering:

• Hard hat sweatbands — Terry cloth or moisture-wicking replaceable liners that absorb sweat and reduce skin irritation. Replace them every few weeks.
• Brim-mounted clips — Attach safety glasses, ear protection, or a small flashlight to your hard hat without fumbling with separate straps.
• Neck shades — A sun shade that attaches to the back of your hard hat and covers your neck. Essential in summer months, especially for long outdoor inspections. Reduces heat fatigue significantly.
• Suspension upgrades — If your hard hat has a basic 4-point suspension, upgrading to a padded or ratchet-adjust suspension improves comfort for all-day wear.

None of these are expensive (most are under $15), but they make a real difference in how you feel after eight hours on site — which directly affects whether you can open your study materials that evening or just collapse on the couch.

Tape Measures and Levels

Every field engineer needs a reliable tape measure, and there is a noticeable difference between a cheap one and a quality tool. A good tape measure locks securely, has a standout (how far you can extend it horizontally before it collapses) of at least 10 feet, and has clear markings that are easy to read in low light or at arm’s length.

Stanley FatMax

The Stanley FatMax is the workhorse tape measure that most field engineers end up with. It has an 13-foot standout, a wide blade that is easy to read, and a Mylar-coated blade that resists wear. The 25-foot version covers most field measurement needs. The housing is impact-resistant, which matters when it inevitably gets dropped from a ladder or knocked off a table.

Milwaukee Magnetic Tape Measure

If you work around steel — structural steel, rebar, metal framing — a magnetic tape measure saves time. The Milwaukee magnetic models have rare-earth magnets in the hook that grab onto steel surfaces and hold, so you can take measurements one-handed. This is a small convenience that adds up over dozens of daily measurements.

Safety Vests and PPE

If you are required to wear high-visibility gear on site, it is worth spending a few extra dollars on a vest that breathes and fits well. You are going to wear it for hours at a time, often in warm conditions, and a poorly designed vest that traps heat will drain your energy faster than any engineering problem.

What to look for:

• ANSI/ISEA Class 2 or Class 3 — Class 2 is the minimum for most engineering site visits. Class 3 provides more coverage and is required for some highway or heavy construction work. Check your employer’s requirements.
• Mesh construction — Mesh vests are significantly cooler than solid fabric. Look for lightweight, breathable mesh with reflective tape that meets ANSI standards.
• Pockets — Multiple pockets are genuinely useful for field engineers. Radio pocket, pen pockets, an interior pocket for your phone, and a large back pocket for folded documents or a field notebook. Some vests have a tablet-sized interior pocket.
• Zipper vs. breakaway — Zipper vests stay on securely and look more professional. Breakaway vests are required in some environments where snag hazards exist (around moving equipment or conveyors).

Backpacks and Bags

A good work backpack is the single most important organizational tool for an engineer who splits time between the office, the field, and study sessions. You need something that can handle a laptop, a printed reference handbook, your field notebook, PPE, and your lunch — without falling apart after three months of daily use.

Carhartt Legacy Backpack

The Carhartt backpacks are built for people who actually use their bags hard. Rain Defender water-repellent fabric, reinforced stitching at stress points, and a padded laptop compartment. The Legacy series has enough structure to stand upright when you set it down on a muddy site, and enough pockets to keep your work gear and study materials organized without digging through everything to find your pencil.

5.11 Tactical RUSH Series

If you want something with even more organization, the 5.11 Tactical RUSH series offers MOLLE webbing for attaching pouches, compression straps, and a compartment layout designed for people who carry a lot of different things. These bags are overbuilt in the best way — they will outlast your PE exam study period by years. The RUSH12 (24L) is a good everyday size; the RUSH24 (37L) is better if you regularly carry PPE, a hard hat, and study materials together.

Portable Battery and Charger

If you study on your phone or tablet during field work downtime, a dead battery ends your study session. A portable charger is cheap insurance. The Anker PowerCore series is the most reliable option in the portable charger market — compact, fast-charging, and durable enough to toss in a work bag without worrying about it.

What size to get:

• 10,000 mAh — Enough for 2 to 3 full phone charges. Small enough to fit in a vest pocket. Good if you mostly just need to keep your phone alive for a study app and occasional calls.
• 20,000 mAh — Enough for 4 to 5 phone charges or one full tablet charge. Slightly heavier but still backpack-friendly. Better for long field days or if you study on a tablet.

Look for models with USB-C Power Delivery for fast charging — a 20-minute charge during a break can give you hours of study time. Keep the charger topped off each night so it is always ready.
