RIRSC TriEye 20% off Club Discount

There is no tax or shipping fee added to the special club prices listed here. You will find the dual-mirror rowing versions under the View category. You can pass the link to friends in other places and they will also get the 20% off. Besides the dual-mirror version, Trieye also makes a single rear-view mirror version popular with bicyclists. Under Clip, you will also find the single-mirror version that clips on prescription lenses in either clear lens or polarized.

A couple of real benefits I've noticed about using these already:

• Each mirror can have its own function. I set the mirror on my left (where I used to have my single round mirror) to see the direction of the boat and any immediate small obstacles. Then the right mirror shows me a wider horizon view.

• If you're rowing into the sun, you're using two mirrors at different angles, so one will be out of the direct line of the sun.

• Glancing at the dual mirrors seems very natural, much like using vehicle side-view mirrors.

• Plus you get the obvious benefits of a wider overall view, less head turning, less shoulder movement and body twist looking to see where you are going. This means fewer pauses in your stroke.

Here are all of the dual-mirror rower versions explained, as well as the clip-on options:

The Sharp model listed under High Contrast is meant to sharpen your vision in low-light conditions by adding contrast and definition when the sky is grey. Sharp model is $79.20 with our 20% Club Discount.

TriEye's Polarized model is the best for a darker shade to cut bright glare from the sun. They are $121.68 with our 20% Club Discount. Shading darkness of up to category 3.
