Singers, musicians, and music lovers will love the Westone MACH 40, a pair of quad-driver universal-fit in-ear monitors that feature warm balanced lows, mids, and highs with a 3-way passive crossover that provides clarity and responsiveness for any kind of music. The monitors are well suited for onstage monitoring, vocalists, guitar players, keyboard players, drummers, and sound engineers, as well as critical listening and general enjoyment.

The earphones employ Westone’s proprietary quad-driver system, utilizing two low frequency drivers, a mid driver, and a high frequency driver, which combine to deliver a frequency response of 10 Hz to 20 kHz at a sensitivity of 100 dB SPL. The MACH 40 features a Linum Estron SuperBaX cable with a low 0.75 ohms of resistance, to meet the needs of audiophiles in the constant pursuit of the perfect audio setup. The SuperBaX conveys music with precision and grace, while the lightweight cable disappears on your ear, allowing you to focus on what matters most. Included with these earphones are five pairs of silicone eartips of various sizes, five pairs of foam eartips (also in various sizes), an audio cloth bag, and an impact-resistant Pelican Case.

Just Right!
Format: Hardcover
Now in its second edition, this book by Terry G. Carter, J. Scott Duvall, and J. Daniel Hayes lives up to its subtitle: a hands-on approach to preparing, developing, and delivering the sermon. It strikes me as a success because of its clear value as a first textbook for someone learning how to put together a sermon. It does better than most at keeping a big-picture view as it assembles the pieces of the sermon. There are other books that, perhaps, dive deeper into the details – the works of Jerry Vines comes to mind – but this one may be “just right” for a wide array of readers. The book is divided into three parts: eight chapters on developing and preaching a sermon, three chapters on preaching the New Testament, and four chapters on preaching the Old Testament. Duvall and Hays had earlier produced a hermeneutics textbook entitled Grasping God’s Word, which is also published by Zondervan, so this book assumes an understanding of hermeneutics and goes straight into putting together a sermon after that work has been done. The first chapter introduces their 11-step sermon process. Chapter 2 covers the first five steps: grasp the meaning of the text in their town, measure the width of the interpretive river, cross the principlizing bridge, consult the biblical map, and grasp the text in our town. As you can see, they word this information in practical terms aimed at our maximum understanding. Again, they avoid being either too shallow or too deep and succeed at being “just right”. After all that wonderful help for putting the sermon together, the other two parts on the Old and New Testaments look at the genres and their unique challenges for the preacher found in each. Most of these were wonderful. The value of the chapter on preaching Revelation might correspond to your own prophetic viewpoint. Actually, they tell you that that might be the case when you preach the Book of Revelation. If you’ve been called to preach and are trying to figure out how to put a sermon together, you owe it to yourself to check this book out. I received this book free from the publisher. I was not required to write a positive review. The opinions I have expressed are my own. I am disclosing this in accordance with the Federal Trade Commission’s 16 CFR, Part 255.

Great reference
Format: Paperback
I used this reference a good but when I was new to practice in a walk-in clinic. From animal bites to corneal abrasions to toenail avulsions, it gave concise treatment recommendations that helped me through my cases. While I need to rely on it a lot less now, I did purchase this to update an older edition and I’ve been equally happy with it

Terrific resource
I work in an urgent care and have been practicing for a little over a year now. This is the perfect resource! I love the ebook option as well with videos that walk you through some procedures. I would definitely recommend buying this if you are a new provider or new to an urgent care setting!
