meet vert

vert is the world's first horse-head angle sensor and display. It attaches to the headpiece of your bridle at the poll and measures your horse's head angle in relation to the vertical, then displays the angle to you with a colored light.

how vert works

As your horse flexes at the poll or rounds his neck, a precise digital sensor detects the angle of the head. Vert emits a light that changes color according to the head angle.

mode: red alert

In the default mode, the light stays off when the head is on or ahead of the vertical. If the head goes behind the vertical, vert emits a red light. It's that simple.

mode: three zones

This mode gives you a continuous indication of the head angle. Ahead of the vertical, blue light. On the vertical, green light. Behind the vertical, red light. You adjust the zones to suit your needs.

no mirrors, no problem

Indoors or outdoors, in the arena or on the trail, by yourself or with a trainer, vert monitors and informs you about your horse’s head position, with no mirrors required.

ride with precision

Ride with consistency and precision every day. Coming soon: features to record your rides for analysis, plus advanced display modes to give you feedback through all stages of a test.

adjusts to your needs

The settings are easily adjusted. You choose an acceptable range of head positions. For a green horse, allow a broader center zone. For the advanced horse, use a narrow center zone or add an extra zone.

Frequent Comments & Questions

Are there any monthly fees?

There will never be any additional charges for the basic functions of Vert; the app is free to download and to use. In the future, we may add new features which may have associated fees.

Will the strap work on a wide crownpiece?

Yes. We include a strap that's much longer than necessary so that you can cut it to fit your particular bridle. Vert has been tested on many bridles, including "anatomical" bridles with complex shapes.

"This does not replace proper instruction."

Correct. Vert is a measurement and feedback tool. It can be used to enhance your existing instruction and lesson regimen, working in cooperation with your trainer.

"Head position should not be the sole focus."

We absolutely agree. The position of the horse’s head is useful information, but must always be evaluated within the larger context of how the entire body of the horse is moving.

"Whatever happened to feel?"

Vert does not replace a rider's feel. Some riders use Vert to help them learn feel. Others use Vert to test themselves, or to be sure of what they feel. Riders can even use Vert to help prevent bad habits from starting.

"Why use a device to see head position?"

If the horse is straight, it’s not possible to accurately determine the head angle from the saddle. Many riders do not have access to mirrors, or "eyes on the ground". Vert provides independent, direct, continuous feedback on head position.

"Why is it important to be on the vertical?"

When the horse's nose is behind the vertical, it is a red flag for problems in the generation and/or transmission of energy from the hindquarters. (And, of course, large angles behind the vertical are a serious horse welfare issue.) In contrast, the nose moving or staying too far ahead of the vertical can indicate evasion.

"Riders will look down all the time!"

Riders should avoid the temptation to stare at the poll, with or without Vert. The color changes are obvious in your peripheral vision, so there is no need to stare at Vert. In practice, most riders report looking down for the first few circles around the arena, but the novelty soon wears off and they return to looking ahead.
