The Vetta V100HR looks pretty nice, you're right.
Do you think it's a better, more reliable unit than the Polar s520?
You mentioned you'd used a Polar before....
The features look pretty comparable, more than enough for my needs.
(It sounds good that the Vetta batteries are consumer-replaceable.)
I got the Vetta over a year ago and used it most of last season. At the time I got it I was considering the s520 and 720. It basically came down to price for features and the fact I didn't care about downloading the data. The Polar I used to use I still have and use rarely, mostly for running. It used to cut out on me under the powerlines on some local trails but I think polar has fixed that problem with the newer units.
Does that Geko do time, total distance, ride distance, etc.? On the site it seems it's basically a GPS; I couldn't tell what other additional features similar to a cyclo computer it has.
It has 5 screens. 1) Satellites 2) track (your basic breadcrumb) which zooms from 50ft to 800 miles 3) compass and/or route director 4) user selectable 4 item display - display four items like speed, odometer, avg. speed, time-of-day (you can pick from 25 items like time to destination, vertical speed, max-speed, moving time, trip time, elevation, etc.) 5) "menu" for waypoints, tracks, routes, preferences.
There are times I miss knowing my heart-rate at a glance, but I've been riding so long I can basically tell what zone I'm in.
Anyway, I bought that V100HR on eBay for $120 .. I think that might still be about the going rate. I think it's worth it for the features.
