C2 appears to have switched from "generator assembly" (PN 1887) in the 1st gen Model D (PM3), to "sensor coil" (PN 2401) in all subsequent Model Ds (which were delivered with PM3 or PM4 or PM5). https://www.concept2.com/support/indoor-rowers/model-d/manuals-and-schematics Model C, on the other hand,...

not sure if the pm3 displays the force curve, but if yes what's the shape of yours with each stroke? PM3's have a force curve, but it is a bit less accurate with the older sensor setup (3 magnets and a small coil) as it only provides 3 signals per rotation instead of the current 6/infinite. Don't k...

The PM3/4/5 are true ergometers in that they measure power (watts) delivered to the flywheel, independent of drag factor, stroke rate, or anything else. If you want to increase power there are three ways: pull harder, use a longer stroke, or use a higher stroke rate. Drag factor has only a second-or...

I have Coospo 808S, Garmin Dual, and Polar H9. I like the Coospo best. It beeps twice when it connects, and once when it disconnects. I seldom notice the light, but I always listen for the beeps. I've had no end of grief with the H9 strap. Coospo is fine after 1.5 years and a couple of hundred hours...

Also, I changed my HR strap today as my old one (about 12 months old, at a guess) was telling me my starting HR was 120. Thankfully the new strap has worked and I dont need to see a cardiologist Compiling anecdotes. Is your HRM a Polar? How old and how many hours? Is your replacement strap Polar or...

Grabbing at straws: Are you using ANT+ or Bluetooth? Maybe try the other.

If you haven't signed up to log.concept2.com, do so now. ErgData will upload your results there. There are challenges from time to time, and a daily workout. Also, you can join a team. If you poke around you can find a list. I started rowing around 1989 on a Model B in the gym. Then I bought an AirR...

Polar Transmitter/Garmin Strap Field Results. Executive Summary: Polar H9 + Garmin Dual belt + KY Jelly worked flawlessly on 10k run (ANT+ Garmin watch receiver), 1 minute treadmill (5khz Gymlink), 1 minute elliptical (5khz Gymlink), 1 minute row (PM3/Gymlink), 1 minute row (PM5/Ant+), 1 minute Bike...

Third strap experiment. I measured the resistance from the snap to the electrode, using a coin with KY jelly to connect to the electrode, rather than just the tip of the multimeter probe. Resistances for each side: Coospo (very heavily used, 2 yrs old): 190/147 ohms. Garmin (somewhat heavily used, 1...

Goodhart's Law (originally coined by Goodhart, who was Governor of the Bank of England) Good point well made....but the pedant in me must correct (sorry). Charles Goodhart worked for the Bank of England for quite a few years but was an Economist and Senior Advisor - never the Governor nor Deputy or...

Don't use a crap multimeter. First I would change the battery in the multimeter, they need power to drive the Ohm's range. Just tried it on all four of my meters, Fluke 8842, Fluke 87V, Beckman HD110 and a Meterman 34XR and they all produced similar results near 100 Ohms on the AliExpress straps th...

Goodhart's Law (originally coined by Goodhart, who was Governor of the Bank of England) is commonly paraphrased as: "When a measure becomes a target, it ceases to be a good measure". https://en.wikipedia.org/wiki/Goodhart%27s_law I think this applies to heart rate, lactate, HRV. These measurements c...

I'll start a new thread once I get some more sensible/repeatable results. So I measured the snap-to-snap resistance of my four snap-on belts with clean hard tap water: Polar H9 (somewhat used): 3.2 Meg ohms. Polar H9 (harldy used): 170 K ohms. Garmin Dual (heavily used): 780 K ohms. Coospo 808S (ver...

My ErgData is not being sent to my logbook, anybody know how to fix this problem? I think it was a transient problem with the logbook server. If you try again, I bet it will work. As for your unuploaded workout, you can enter it manually, or used Concept 2 Utility. Note that I started another threa...
