We need a simple, on bike lap timer that we can see at a quick glance while riding down the straights. All we really need is timing for the last lap, although partial laps would be great so we could see if we were making progress in a certain turn. Suggestions? What do you use?
Thanks,
Team 19
AIM Solo GPS. Price is good. Big display and I think you can get a discount through Shandra. And lots of features but you can keep it simple: best lap, predictive lap splits, speed all available. Very good GPS.
AIM Solo here as well. It's been very reliable for me and all the tracks CMRA currently races at are already preloaded.
You are welcome to come by and check it out at Hallett.

i think something like this is what you guys need.
Hahaha
How much are the AIM solo and do any track venders/sponsors sell them?
For mark, I can get them for $365, that's the cmra discount price. If you want one,please drop me a note at cmrapromotions@gmail.com. thanks !
I forget the price but I got an AIM solo from Shandra as well. At the time she sold them at the track and I remember the price was a good $50 less that anywhere else. All the CMRA tracks are pre loaded. It also works at TMGP tracks just need to hit a button as start/finish line and complete one lap. It learns the course and will start giving lap times after that.
It has the basic info you want on screen plus it displays all your lap times after a run including min/max speed.
You can also hook it up to your computer with the included software and really get into a lot a data.
I'm a Prov Novice, so please excuse my rookie question, can you not use a smart phone with one of the available apps such as Harry's Lap Timer or TrackAddict?
I have an old iPhone4, that has been susperceeded by my iPhone5 for normal phone use, that I use with Harry's Lap Timer for capturing lap times at track days. I also use it with a Bluetooth GPS receiver to give higher GPS sample rates. The iPhone4 samples GPS once a second, with the GPS receiver, it samples 5 times a second and their are more expensive units that sample at higher rates.
I've considered that. Others have done it. There are some challenges but maybe worthwhile if you can overcome or deal with them. 1. Finding a spare device. 2. Determining how to get it running. 3. Interface complexity, especially while riding or pre-ride, especially with gloves. 4. Reading itQuote:

You basically use your current phone as a hotspot (you only have to do it once, it may seem like a pain but it's not) and tether the iphone to that, pick the track and that's about it. It's very accurate, i've checked it against my transponder and it was dead on. It's already got the start/finish line and splits, as well as being specific for track direction. It keeps a log of your laps and always shows a reference lap, that you can choose. I made a bracket that's attached to the fairing stay and positions the iphone above the gauges so you look through it as your looking through the wind screen. It works very well, as your heading to the finish line, you can see your target time and the distance to the finish line. It puts everything in perspective, it's also got a green and red meter that tells you if your ahead or behind of your best lap.
Will the phone battery last for 6 or 8 hours with the GPS active?
I am currently looking at the some of the more expensive lap timers, as I want more data to look at these days. But the Harry's is an accurate and inexpensive way to see what your running, plus the iphone is small and light weight and can be mounted just about anywhere. It's a hodgepodge system, but it does work.
I added a usb power port to our endurance bike, and plugged them both into it. I don't use the onboard GPS, I use a Dual brand GPS reciever, it's tethered via bluetooth.Quote:

this guy is selling home made gps lap timers for $99 ish i think.
There is also a small rod (stick) you can attach to your tank , and see the sun's shadow as you finish each lap! :tongue:
Showing your age there Eric! :biggrin:Quote:

I really like my AIM solo, it is nice to put on predictive lap timing if you have a gopro and re-watch the laps and see where you make up or lose time. Also, the software is pretty easy to use. Normally you just turn it on and go and it all works flawlessly, the only exception so far being it thinks the start finish is right before Rattle Snake going CCW when it is actually before big bend. But, you can change that and it will be correct when going CW.
