So I used the tour to test out a Sena SMH10R Bluetooth intercom ( retail $670) connecting to my iPhone 6 which I had mounted on the handlebars via a Givi phone holder ( retail $70).
I normally use UHF radios for training rides, with good results. For this trip I had different requirements though.
I didn't need to talk to students; I simply wanted to follow directions if needed, or change my route while on the move, if we encountered road works or slow traffic.
I also wondered if it would be helpful to be able to take calls while on the road, given I would be travelling for several days.
Previously I've had mixed feelings about being distracted by devices - I don't, for example, listen to music while riding after a near miss with a piece of Scottish granite mountainside many many years ago when aged 18 and onboard a heavily loaded up Kawasaki zx10 ( yes the FIRST version !). I was listening to and getting carried away with some Iron Maiden and failed to notice some gravel in the road while cranked over at "making good progress" speed in a fairly interesting right hander..
And now, after the trip, I still have mixed feelings.
Summary of initial +/- points:
my phone lasted most of the day ( needs a usb power connection really though - how do I make that watertight? ) while the intercom batteries were still fine after 12 hours. I wasn't talking or making calls though - just had navigation on in the background at times. The intercom is easy to use and connected to my phone automatically after the first setup. No hassle at all.
I did briefly answer one call at 80kmh and the person could hear me fine. I didn't like the distraction though.
Worse though was the fact I had to remove my glove to operate the phone through the screen of the Givi holder.
And more annoyingly, on a warm day in the sun, the phone got so hot in the case that it switched off and needed placing in with the Magnum ice cream in the local dairy freezer for a short while..
The intercom sits on the outside of the helmet and at low speeds there is little wind noise. Maybe it was where I had placed it, but I found at 100km/h + there was considerable wind noise on that side, but better with an ear plug in. I needed to hear directions with the other ear through the helmet mounted speakers, so only used one ear plug.
It is worth the $700+ investment? Not sure, for a trip like this. I like to
mix things up if necessary and generally carry a rough idea of a route in my head. And I don't generally want to call people when riding, or receive calls. I'm trying to get away from all that!
I will probably use it for advanced rider training though, when I need good 2 way Comms with a rider I am training. Although that means fitting the 2nd unit to their helmet too.
