I use the simple, effective & accurate Sportsline from Wally World…
They have a variety w/options rivaling more expensive models. I chose to use these simpler models as to not detract from the training giving the person something else to worry about.
These little monitors are tuff, easy to operate & the company offers a warranty they have stood behind @ least w/me. I see no purpose in excess spending for cute gadgets that offer many un-needed features for what i use them for.
My classes r ruff & these lil things take a beat’n sometimes. Clients that come in with their own big name brands experience similar problems when they occur w/their apparatus so 4 the $ spent these are effective for my setting.
Consistently test’s good against Polar, Reebok & Garmin models
