T-5020 Fitness Interval Timer, Multi-Functional Training Timer with Pacer Black

The instructions are great. I found them to be very straightforward. This device is perfect for timing up to two intervals. The frequency setting in Pace mode was a little tricky. If you are pacing steps, and you want the frequency/footfall of each step to be every second, set the frequency for 0060. That’s a pace of 60 [units/steps] per minute. Think of it like beats per minute on a metronome. Also check out the Leap device and the Taylor timer (not an interval timer, but dead-simple to use and has a flashing light if you want it.)

Could be made easier to figure out how to set it, but I figured it out. Other than that, once you do figure it out (it's easier than Rubik's Cube, but harder than Tic Tac Tow), it is a very helpful and convenient and appreciated device.

Really nice

Difficult to operate. I got this originally for my dad. He hated it. lol hard for him to see the numbers

This works nice for two activity HIIT, but also for splitting large runs into easy pieces. I will create 2 reps of 7:30/7:30 activities for a 30 minute run. This way, I receive a buzz on my hip at 1/4, 1/2, 3/4, and completion at the 30 minute mark, without looking at a watch.

I’ve never had a specific interval timer before. When I went to a 3-day boxing clinic the trainer’s interval timer was much larger. And so far, having read the instructions 3 times, I still am unable to set it. Once I get that working perhaps this thing will be functioning like crazy.

Too difficult to program

Love it. My back up to my other clock
