Had something really funky happen this week at practice. Ergometer trouble.
The team was rowing a fairly standard Monday practice for us. Three sets of pyramids, with one set being:
- 30 sec on/ 60 sec active rest
- 60 sec on/ 60 sec active rest
- 90 sec on/ 60 sec active rest
- 60 sec on/ 60 sec active rest
- 30 sec/ 60 sec active rest
- rest period
We were on our second wave of these, when suddenly 11 of the 12 erg monitors froze. During the pressure piece. Solid. Like ICEBERG frozen.
All-at-the-exact-same-time.
I know it was at the same time because 11 rowers simultaneously freaked and hollered, “Coach!! Something’s wrong!!”
Facts Of The Matter
What I know for sure is that:
- the display was on power graph display
- the graphs froze in mid refresh
- the time went to “:00r” and all seemed to freeze on 23 spm
- 11 of 12 froze all at exactly the same time
- they froze for several minutes
- the monitors were a collection of PM3, PM4, and PM5s
- one erg was not impacted in any manner
- I had updated all the monitors software just weeks before
- the ergometers were not electronically connected
- no other electronics (phone, radio, watches…) in the room were impacted
It was just plain bizarre.
The Cavalry
One thing I love about Concept2 is their customer service.
Love it.
They set the example not just for rowing businesses, but businesses across the board. (I’m not paid to say that, I truly believe it!).

So I called C2, and talked to customer service. Then one of their developers.
We exchanged info and spent two days communicating back and forth about what it could be. Neither they, nor I had ever had an issue like this.
I’ll say this, over the past 20+ years I’ve had few ergometer troubles. I might have had two or three C2 monitors have a problem. But that was almost always due to a battery issue, and in one case a worn wire.
In my freaky case the prime suspects were:
- Power surge
- Wifi surge
- Elector magnetic pulse
- Nuclear blast
With a little bit of digging I can say we ruled out suspects 1 – 4 (thankfully). So that leaves us with a mystery.
I ran diagnostics on several of the monitors, and sent that along to Concpet2.
It’s a stumper.
Maybe the diagnostics will shed some light.
I will share what we find.
