# Model Descriptions

The **Power Meter** is a physiology tool - for monitoring training intensity, measuring training load and tracking fitness development by measuring Power (Watts) and providing feedback once-a-second or once-per-stroke.

The **Power Meter w/ High Speed Data** builds on the physiology focused features of the **Power Meter** and adds biomechanics/technique focused features in the form of additional real-time metrics and the introduction of High Speed Data. The features of the **Power Meter w/ High Speed Data** are a superset of those found in the **Power Meter**.

We encourage those who aren't sport scientists or researchers; those who don't have access to a sport scientist or a highly analytical coach, or those who aren't part of a national team (where access to sport science expertise is a safe assumption and team boat paddling is common) to opt for the **Power Meter** as the additional features of the **Power Meter w/ High Speed Data** may not be effectively utilized in all cases.

On the flip-side, if you have access to a sport scientist (particularly if they have a background in biomechanics) and/or team boat paddling is common (where detailed stroke-timing between athletes may be investigated) then we strongly recommend opting for the **Power Meter w/ High Speed Data**.
