B37v2 vs Kestrel: Key Differences
Stroke length
The Kestrel features a 13mm stroke length, which is designed to provide effective muscle penetration without being overwhelming. This depth is refined based on user feedback to balance intensity and comfort. The B37v2 data does not list a specific stroke length, so you cannot compare the physical reach of the massage head directly. A longer stroke generally allows for deeper tissue engagement, which matters for deep tissue goals. Without the B37v2 spec, the Kestrel has the clear advantage in documented penetration depth.
Speed range
The Kestrel offers 6 speed settings ranging from 1800 to 3500 RPM. This broader range gives you more options to fine-tune the intensity for different muscle groups. The B37v2 provides 5 speeds between 1400 and 3200 RPM. While the B37v2 starts slower, the Kestrel reaches higher maximum speeds. If you need the highest possible intensity for deep tissue work, the Kestrel’s upper limit is superior. The Kestrel also uses a scroll wheel for smoother transitions between these speeds.
Handle design
The B37v2 has a unique 15-degree angled handle. This ergonomic design helps you reach your back more easily and reduces arm fatigue during use. It is specifically noted as ideal for back massage. The Kestrel features a textured grip and a chrome bezel for better handling comfort. While the Kestrel’s grip is enhanced, the B37v2’s angled design offers a distinct mechanical advantage for self-massage on hard-to-reach areas like the upper back.
Attachments
The Kestrel includes 6 locking attachments, which is more than any previous model from the brand. It features a new air-cushion attachment for targeted treatments. The B37v2 comes with 4 locking attachments, including a new silicone ball. The Kestrel provides a larger variety of tools for different muscle groups. If you want more options for customized relief, the Kestrel’s expanded set is the better choice. The B37v2 offers fewer, but still versatile, options.
Battery life
The B37v2 offers up to 8 hours of battery life. This extended runtime allows for extensive treatment sessions without frequent recharging. The Kestrel data does not list a specific battery duration, though it supports USB-C PD fast charging. The B37v2’s documented 8-hour capacity is a significant advantage for long-term use or travel. You can rely on the B37v2 for longer sessions without worrying about power levels.
Choose the right Ekrin model
Users needing deep back coverage

Combined with its deep tissue focus, it offers a potent massage experience tailored for those who need targeted relief in hard-to-reach areas.
Those wanting precise speed control
The Kestrel includes an intuitive scroll wheel for adjusting speeds. This allows for seamless transitions between its six settings, ranging from 1800 to 3500 RPM. You can quickly fine-tune the intensity without cycling through options. This feature provides greater control over your massage experience compared to standard button-based adjustments.
Users seeking extended battery life
The B37v2 offers a battery life of up to 8 hours. This extended duration supports extensive treatment sessions without the need for frequent recharging. With USB-C PD charging, you can power up efficiently. This makes it a reliable choice for long-term use or travel where consistent power is essential.
Those preferring a wider grip
The Kestrel has a narrower width of 2.5 inches, compared to the B37v2's 3.15 inches. This slimmer profile may offer a different handling feel. It also includes a textured grip and chrome bezel for enhanced comfort. These design elements aim to improve control and stability during prolonged massage sessions.

Frequently asked questions
Is the Ekrin B37v2 better for back pain than the Kestrel?
Yes, if you struggle with hard-to-reach areas. The B37v2 includes a 15-degree angled handle designed specifically for ergonomic reach on your back. This shape reduces arm fatigue while you apply deep tissue pressure. The Kestrel is a straight gun, making it less ideal for self-treating your own back without assistance.
Does the Kestrel have a longer stroke than the B37v2?
The Kestrel features a 13mm stroke length for deeper muscle penetration. This depth balances intensity and comfort based on user feedback. The B37v2 data does not list a specific stroke length, so you cannot directly compare the mechanical depth. You must rely on the B37v2’s angled design for leverage rather than raw stroke metrics.
Are both Ekrin massage guns the same weight?
Yes, both models weigh exactly 2.2 pounds. This shared weight makes them similarly portable for travel or gym bags. However, the B37v2 is a 6-piece set, which adds bulk to your carrying case. The Kestrel is a single unit, offering a more streamlined profile despite the identical hand-held weight.
Which model is better for general recovery or pain relief?
The choice depends on your primary goal. The B37v2 is intended for pain relief with a deep tissue focus. The Kestrel is marketed for recovery with precise control. If you need targeted relief for specific sore spots, the Kestrel’s scroll wheel offers tactile adjustments. For broader ergonomic comfort, the B37v2’s angle helps.

The Kestrel is taller at 9.75 inches, while the B37v2 is shorter at 5.91 inches. The B37v2 is wider at 3.15 inches compared to the Kestrel’s 2.5 inches. These differences affect how the device fits in your hand and your storage space. The Kestrel’s height accommodates its longer body and stroke mechanism.
Can I use the B37v2 for deep tissue work?
Yes, the B37v2 is explicitly labeled as a deep tissue massager. It is designed for users who prioritize deep tissue relief. The angled handle helps you apply consistent pressure to difficult areas. This makes it a practical tool for addressing chronic tension in the back and shoulders without straining your wrist.
