Most probably is caused by interference from other heart rate monitors. Would help if you advised the brand/model of your HRM to determine what sort of wireless communications is used between chest strap and computer (ie: 5 kHz or 2.4 GHz).

Sorry, assumed your computer also had HRM functions. Yes, it is strange that a simple wired bike computer plays up when in an environment with high density "electrical noise". What brand & model of bike computer do you have? I assume it has a long cable rear wheel speed sensor to work on a trainer - if so the cable could be acting as an antenna. I've never had any problems with 2.4 GHz wireless units (Polar CS600 or Garmin 705) with rear wheel speed sensors in a spin class.

I used to have one of these on my MTB about 7 years ago. Recommend you spoil yourself and upgrade to 2.4 GHz HRM c/w cadence, speed, altitude, datalogging, etc. so you can download rides to your PC, training diary, etc. Its a whole new world once you've experienced it! Any you'd never go back to a cheap bike computer ;-)

Troy,
what is it doing when you say it is playing up?
and is it wireless or hardwired?
nice to see Garrin likes his new 705. They are highly recommended.

Troy,
no doubt it is entertaining/distracting during a spin class. I would be asking the Australian distributer for any suggestions.
From here It appears to be Southcott email
I would be interested in learning the reply.
