II. Models and Availability
The Protege is available in three very similar models: 5, 8, and 9.
Shown is the Protege 9 which has the following functions:
1. Current speed
2. Ride time
3. Trip distance (can be used to display revolutions)
4. Dual odometers for two wheel sizes
5. Odometer for total of dual odometers
6. Average speed
7. Maximum speed
8. Clock
9. Speed comparator (speed compared with average speed)
10.Temperature
The first three functions are continuously displayed on the first three lines and the others are selected for the fourth by momentarily pushing the body of the computer forward.
The Protege 8 has the same functions as the 9 except that it does not display temperature.
The Protege 5 does not display temperature, average and maximum speed, and a speed comparator. It has only a single wheel size setting for a single odometer and therefore cannot be instantly converted to a normal bicycle computer. Also it cannot be used to make secondary measurements while suspending the primary one. Although it works as well as a revolution counter and may be simpler to program, the slightly smaller price does not justify its purchase over the other models.
The above models can be purchased at many bicycle stores and on-line sites such as planetbike.com. Jensonusa sells model 5 for $15 and 9 for $20 at their Ontario, CA, store and also on-line for the same price with an additional cost for shipping of $5.95 for one and $6.95 for two computers.
