RFID / NFC Option


This technology can be helpful if you are a gym or professional business where you'd like to track the usage and age of your ropes.

RFID is how items are uniquely identified using radio waves (Radio Frequency Identification). It's for 1-way communication from 10cm to 100m away depending on the frequency. Example: Airport Baggage.

NFC is a subset of RFID that is restrained to close proximity communication typically less than 10cm (Near Field Communication). NFC chips can operate a 2-way signal to exchange information. Example: Apple Pay.

Climbing Gear Review no rating given just a review

Touted as the lightest single rope in the world, the Opera 8.5 weighs in at a mind-bending 48 g/m—that’s 7.4 lbs. for the 70-meter version. Rated as a single, half, and twin, its uses are endless, and our testers “took this rope for multi-pitch alpine to ice toproping to redpoints of mixed routes.” We don’t recommend making this your workhorse cord, but it stands out for alpine with its airy weight and incredible UIAA-certified Golden Dry treatment. “After full days in Ouray’s Box Canyon getting clobbered by falling ice and dipping into the river, the Opera was still bone-dry at the end.” Plus, Unicore keeps the core protected if the sheath gets cut.

Climbing Zine Gear Review no rating given just a review

The Beal Opera is a versatile rope that provides alpine enthusiasts with the ability to simply carry less weight without sacrificing the safety margin provided by a UIAA single rating. It can be carried alone for single use on ice and rock climbs, or as a set of burly double ropes on wandering routes or routes that require 60+ meter rappels. The slinky Opera is not designed to take the abuse of repeated sport whipping or excessive top-roping, but you can use it with confidence on redpoint burns or classic climbs in the mountains, knowing that you are only cutting weight, not safety.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
