Coxmate SCT testing

The new Coxmate SCT has been out and about being tested by clubs around the UK.

Alex Henshilwood at Eton College wrote with some great questions and we got answers from the manufacturer which are reproduced below.

I've used the Coxmate (very Aussie name, mate) and have the following comments:

  • excellent functionality, "cover" readings are especially useful
  • computer down-load fast and easy to operate, great graphs and the split facility is very good
  • it looks rather "Heath Robinson" in construction – is it a prototype?

A few issues:

  • I have not used the supplied impeller, preferring to use an NK one.
  • Calibration very easy, and the impeller from NK is considerably better than the Coxmate version
  • The mic lead look rather flimsy and thin, so am not sure about durability when submitted to the "boy test"
  • Does the SC T have a built in radio, and how might this work (channel etc) if so?


Finally, really like it and would like to know how much two would cost without speakers.
Thanks for giving me the opportunity to test drive it, and I hope that we can find some money!

Coxmate's reply

Some answers to your questions from Peter Hodson the manufacturer. 

  1. 'Heath Robinson'!: It is not a 'production' one – I built this one, and production ones are 'cleaner', but not sure if this would change his impression. We tend to put function ahead of appearance, and in some areas this doesn't help aesthetics. The production ones will have moulded lug for wrist strap with same wrist strap used on SRT. This looks better.
  2. Quite happy for him to use NK impeller, as long as he uses SCT. We are doing a fair bit of work on impeller as you know – making a very tiny one.  But, Alex, if you are using the impeller positioned under the cox / stroke seat you won't get much data on the software about the stroke profile per stroke.  To get that (more accurate) data, you need to position the impeller up in the bows – this is because of the boundary layer and the data distortions you get further to the stern.
  3. Mic Lead: This cable has a steel inner and is much stronger in tension than regular coax. The only mic cable problems we have ever seen was where the mic cable went into cable gland – the compression of gland causing the braid to fail. However we don't have gland any more – and no compression failure point. The connector is filled with epoxy, and would take a lot to pull it off.
  4. Radio: We have radio option for Australia, but unfortunately Europe has different frequencies, so we can't sell it in Europe. We did consider modifying this option for Europe, but the advent of cheap radios has made it unlikely.

Alex has gleaned a lot about the SCT from one outing – pretty good. Already he has seen some of 'the light' of the SC/SCT, and he could get some real benefit from it.  He likes the 'cover' display, wait until he appreciates the speed 'ratio', this has more to offer. It would be fantastic to have him using it regularly. I'd be interested in more feedback from him.
