At Proto, we make scientific advancement possible by bringing you highly accurate and precise x-ray diffractometers. You work hard to achieve your results, so we work hard to provide you with the best equipment on the market. Our highly configurable powder diffraction systems include benchtop units, compact floor units, and full-sized laboratory units.

The compact AXRD® Benchtop system is full-featured yet highly cost effective. The AXRD Theta-Theta system provides a unique solution for high-temperature diffraction, with temperature stages from -190 to 2000ºC, in the convenience of a compact footprint. The powerful AXRD LPD laboratory system can be customized with x-ray optics to best suit your powder experiment needs.

The AXRD LPD-HR is our popular LPD system with upgraded optics to enable the characterization of thin films and single-crystal materials. Finally, the AXRD LPD-HT is the ideal solution for rapid screening and in-situ characterization of multifunctional molecular materials.

Whether you need to determine the composition of raw materials or characterize your products, you can count on our versatile powder diffractometers to provide accurate results.

Proto's lifetime guarantee means we will continue to support, service, and provide upgrade paths for your instrument for decades to come. Rather than requiring you to buy a brand new system when our product line changes, we are committed to keeping your aging instrument running like new.

Sidemount- | Principles For Success

Sidemount diving has gained popularity in recent years, and for good reason. This technique allows divers to explore underwater environments with greater ease, flexibility, and safety. However, like any advanced diving technique, sidemount diving requires a deep understanding of its principles and practices to ensure a successful and enjoyable experience. In this article, we will explore the fundamental principles for success in sidemount diving, covering equipment, techniques, and best practices.

: Stability comes from a combination of correct weighting, lung volume use, and perfectly trimmed cylinders. A successful diver can hold their position in the water without using hands or fins. 3. Essential Operational Skills

Success requires that you adopt a

Why? Because Sidemount doesn’t reward gear. It rewards discipline. Success isn’t about buying the most expensive carbon fiber cylinders; it’s about mastering four hard-won principles.

Do not just copy your backmount weight belt. Sidemount requires strategic weight placement along the harness to keep your hips and shoulders in a single horizontal plane. 2. The Art of Cylinder Trim Sidemount- Principles For Success

The third, and perhaps most critical principle for the technical sidemount diver

Success in sidemount is rarely "out of the box." It requires meticulous fine-tuning. Buy Me a Coffee Bungee Systems Sidemount diving has gained popularity in recent years,

You are holding the tanks because you are afraid they will float away or rotate. They will not. Your bungee loops or magnets (if you use a modern harness) are there to gently manage the valve, not to imprison the cylinder.

Sidemount was born in caves because it solves one problem better than any other configuration: In this article, we will explore the fundamental

| | Consequence | Solution | |-------------|----------------|--------------| | Poorly adjusted bungee | Tanks sag away from the body, creating drag and imbalance. | Adjust bungee length so the valve sits securely in your armpit. | | Ignoring regular regulator switching | One cylinder becomes much heavier, distorting trim. | Switch every 20‑30 bar, or use a timed pattern (e.g., left for one minute, right for one minute). | | Over‑accessorised rig | Snag hazards, increased drag, and cognitive clutter. | Strip your rig down to essentials; add items only when justified. | | Skipping shutdown drills | In a real failure, the diver panics and struggles to reach valves. | Practice shutdowns every dive (or at least weekly) until they become smooth and calm. | | Adding homemade modifications too early | The diver cannot recognise what “correct” feels like, so they accept sub‑optimal performance as normal. | First learn on a proven, optimised rig; then, once you understand the principles, you can experiment. |

This article is based on principles taught by leading sidemount educators including Andy Davis, Steve Davis, Roger Williams, and the Sidemount Pros team. For further learning, explore the Speaking Sidemount podcast, the InDEPTH magazine sidemount editions, and the TDI/SDI sidemount diver programs.

ADVANCED PHOTON-COUNTING DETECTORS

At Proto, we always choose the best possible x-ray detection systems for our equipment, which is why all of our powder diffractometers are equipped with photon-counting detectors. These detectors directly capture x-ray photons and convert them into an electrical signal. This direct conversion is advantageous because it yields zero dark noise, zero readout noise, high dynamic range, and excellent signal to noise. Choose from the SPD advanced point detector with true energy discrimination, the DECTRIS MYTHEN2 linear detector for high-speed powder diffraction, the DECTRIS EIGER2 detector for 2D powder diffraction, or the DECTRIS POLLUX detector for versatile 2D powder diffraction applications.
