Problems with Hac4Pro computer

I bought a Hac4Pro computer/altimeter/heartmonitor.

In every trip the max speed suddenly runs to a very high value. Last time
148 km/h.

I complained and got a new one.

What happens, the new one has the same problems.

What are your experiences with the Hac4Pro ? Anyone known with this

problem

Anyone knows a solution ?

Problems? Other than it is the LEAST reliable, hardest to set up and most
expensive piece of junk computer I've ever come across (and that includes
Trek computers, at least they have the decency to sell them for cheap).
If it doesn't say Cateye or Polar on it, it's not worth it!

Er, my friend's Polar 710 has similar problems. It's fairly common to
wireless computers in general; they're susceptible to electromagnetic
interference from high voltage lines as well as noisy fluorescent light
ballasts. Outdoors, the high voltage lines are the more-likely culprit.
There's a spot on our local "loop" ride that's infamous for causing very
high max speed readings.

The most common cause of anomalous readings in this area
is a proximity detector set into the pavement.

What frequency does the sensor use on wireless cyclocomputers? I have
a heart rate monitor that uses 5 KHz. A common HRM chipset uses 30
KHz. There is a lot of man-made noise at those low frequencies.

The PDF's at www.cateye.com don't cover that type of thing. Any
definitive answers out there? A search didn't turn up anything.
Mostly just curious.

Thanks,
Jim

Interesting. I have a Polar and ride on a road for several miles
beside some jillion-volt towers and never have that sort of problem.

It's a CS200cad and has two wireless sending units, so you'd expect
it to be extra susceptible.

The only times it's misbehaved were when I first got it (the cadence
sender was DOA due to infant mortality) and the one time I came
across another rider with a similar model (something that could
be avoided in the setup if we had cared to, but he's just a bent
rider who was on the road one day; never saw him before or since).

However, I can't recommend the unit because the GUI blows and the
buttons are extremely hard to activate, which can interfere with
controlling the bike and maintaining the flow of the ride. And the
computer-link is audio-based (you hold the thing up to your
microphone and enter the magic sequence), and it only uploads
to their website, not to your computer. Extracting the information
manually is slow due to the super-hard buttons, and slower because
the GUI is, as I said, horrendous. Plus, you can't replace the
batteries in the sending units, you have to get it done at a service
center.

I'd switch to the Cateye, but I got so [censored] at them waiting for them
to finally declare the CC-TR100 vaporware that I refuse to buy from
them
any more.

Yea, but Polar is actually a pretty decent company to deal with. Ciclosport
is just insane. Why would you make a separate Imperial and Continental
model? Why would you choose a US distributor that would mess that up way too
often?
