tindeq progressor dynamometer - do you use it?

I'd like to know how many climbers actually use Tideq Progresso. And how many actually know how to use it?

I've been using it for almost 5 years, but I see that many climbers don't have it or don't know how to use it. Even if they were offered to buy it, they don't use it for the same reason.

Also, most mountain boards aren't suitable.

Any experience?

I'm from Chile. I talk a lot about this for Latin America and Spain, but I'm not sure what the reality is in the US.

I have a pitch6 forceboard and have used a tindeq (same thing). They're not super common. My 2 cents: you 100% don't need one, they are just convenient/a dorky toy for certain things like data gathering. You could do just fine with hangboards/lifting blocks, weights and pulleys. I actually prefer weights and floor lifts for my heavier finger training, but for low intensity repeaters they are more convenient than pulleys and weights for me. You can sit on a couch or in a car doing endurance repeaters which is pretty nifty (but unnecessary).

The primary ways I use a Tindeq Progressor:

•  Climbing Day Check-in: After I warm up, I pull as hard as possible on a 20mm edge with a 120° bend in my arms. I compare that current number to previous check-ins to decide what kind of session I should choose for the day. I want to see that number no less than 5% of my max before a high-intensity session. Otherwise, I choose a volume or capacity session.
• Critical Force Test: I perform the Critical Force Test twice yearly as a benchmark.
• No access to weights: I can systematically train different intensities isometrically, especially long-duration, low-intensity isometrics. It is a game charger for airline travel. 

I have one and found it useful to track my recovery when I had a finger overuse injury. Otherwise, I've found basically zero correlation with my max pulls on the Tindeq and how hard I'm climbing, either short term or long term. I've had excellent climbing days when I couldn't pull my max on the Tindeq and mediocre ones when I pulled a new PR. Since I don't do max pulls anymore, my tested max pull has gone down compared to a year ago, but I've climbed harder grades and sent climbs I couldn't send a year ago.

Personally, I don't use Critical Force; it doesn't give me the information to change my training, and it's also very tiring. I prefer to use long-term performance curves while training.

I need to upload a video about this.
