This watch has everything you need. It's waterproof and can be used for interval sets with ease. Swimming: Intervals sets can be set up as laps and monitored then graphed and comments inserted to graph features, this is for any sport. For biking it is great. I didn't get the cadence for it but still one can use the unit to assess the HR duting elevation rides. It is posted on the graph feature. All is shown on the analysis chart with options to analyse the HRvs other things. OPtions in the software let you look at various attributes of the workout wrt HR , pace, speed, time of many variables and it graphs these as selections. All complete for data analysis. I got the watch for pace during running to maximize training looking at cardiac drift relative to pace and nutrition etc. Works like a chram and has allowed me to stratagize for long runs and pace myself for proper hydration and food. This watch is a must have for people that do IMs.
