Our 2025 Diagnostics Year in Review: Wins, Lessons & What’s Next

In: General

Another year in the books—and what a year it’s been.

At DiagNation, 2025 wasn’t just about selling tools or teaching techniques. It was about pushing the entire industry forward. We’ve spent the last 12 months shoulder-to-shoulder with techs in the trenches, shop owners chasing efficiency, and diagnostic pros trying to stay one step ahead of increasingly complex vehicles.

Now that we’re closing out the year, we’re taking a moment to look back—at what we launched, what you loved, and what we learned. Because every milestone matters, but so does the path ahead.

Let’s break it down.

Product Highlights: What Took Off in 2025

This year marked a major evolution in how diagnostics gets done. The shift toward smarter tools, faster workflows, and deeper data analysis was clear across the board. Here’s what stood out:

Top Sellers of the Year

  • TOPDON Phoenix Max & Smart: These scan tools became a staple in shops coast-to-coast thanks to their balance of power, affordability, and speed. Full-system coverage, fast ECU communication, and intuitive software made them a no-brainer for techs who needed reliable bi-directional control.
  • PicoScope 4425A Advanced Kits: The gold standard in lab scope diagnostics. We had multiple restocks—and sellouts. With more shops doing in-depth waveform analysis, this tool became essential for diagnosing EV systems, network dropouts, and ghost faults that standard scan tools couldn’t catch.
  • BTMobile ProS: This battery and charging system analyzer proved that not all diagnostics need to be complicated to be powerful. A go-to tool for mobile techs and shop bays alike.

Product Launches That Changed the Game

  • TiePie WiFiScope WS6: The first truly portable standalone scope. We launched it mid-year—and immediately saw interest from techs working field calls, fleet jobs, and long-haul data capture. The ability to log data untethered was a huge step forward in remote diagnostics.
  • DiagNation as a Full-Line Distributor: We became official partners for TOPDON, Pico Technology, and TiePie Engineering—which meant faster shipping, deeper inventory, and better support for shops buying high-end tools.

What You Watched, Clicked & Shared

This year’s most popular content wasn’t just about products—it was about how techs actually use them. Our walkthroughs, scope study clips, and training highlights helped hundreds of techs level up.

Top 3 Most-Watched Videos of 2025:

  1. “What’s Wrong with This Waveform?” – A clip from our lab scope study group where Gary broke down an ignition issue in a hybrid system. Tons of comments, real-time engagement, and repeat views.
  2. “TOPDON Phoenix Max: Full Vehicle Topology in 60 Seconds” – A short but effective demo of one of the most loved features on the Max.
  3. “How to Use the TiePie WS6 in Standalone Mode” For techs new to long-data logging, this video answered the “how” and the “why” of advanced diagnostics.

Big thanks to every shop that tagged us, sent in a scope trace, or shared a tool success story. We don’t just talk about the tools we show what they can do in real-world bays.

What We Learned from Supporting You

2025 confirmed what we’ve been saying for years: diagnostics is no longer optional—it’s the heart of your workflow.

Here’s what stood out this year:

  • Shops are getting more diagnostic-specific. More owners are hiring dedicated diagnostic techs or creating internal workflows where diagnostics happens first—and faster.
  • Intermittent issues are on the rise. CAN bus shutdowns. Communication faults. Drivability complaints without codes. These “ghost” problems are showing up more often and scopes are becoming the only reliable way to find them.
  • Training is everything. Whether it’s remote study groups or real-time hotline support, shops that prioritize learning are outperforming the ones that don’t. The difference in efficiency, accuracy, and profit is measurable.
  • Mobile diagnostic techs are booming. Whether filling in for shops, helping fleets, or offering advanced diag on-call, mobile pros are rising fast—and they’re looking for rugged, remote-capable equipment like the WS6.

What’s Coming in 2026?

We’re not slowing down. Here’s a taste of what’s ahead:

  • Live Remote Mentorships: Think “on-demand diagnostics coach.” We’re rolling out a new format of live tech mentorship real instructors, live on the car, when your team needs it most.
  • PicoScope Mastery Series: A new video and training series focused entirely on making you a scope pro. From guided tests to advanced signal analysis, this will be the deep-dive your techs have been waiting for.
  • More Events, More Training: Expect to see us at PAVE, Vision, ATE, and beyond—offering hands-on training, exclusive workshops, and product demos in person and online.
  • New Tool Releases: We can’t reveal too much yet, but we’re working with our partners on new diagnostic kits built specifically for U.S. shops. Faster sampling. Smarter features. More technician control.
