The amount of water in the tank simulates the weight of the boat and crew, the more water in the tank the heavier the boat and crew. The standard Calibration Level is Level 17. If the user is lighter in weight, Level 15-16 can be used. If the user is heavier in weight, level 18-19 can be used. The maximum level to fill the tank is Level 19. DO NOT fill above the maximum level – this could void the warranty.
The Challenge AR features an advanced computer monitor providing the rower with measurable performance output, an ergonomically designed seat that rides on precision bearings and rollers for absolute smoothness, an upgraded footboard with advanced heel support, and an innovative soft grip handle to eliminate stress on the hands and wrist during the comfortable, but physical workout.

The dense resistance of water creates substantial drag, but on the WaterRower models, this is perfectly tempered by a whippy cord. It coils and recoils with such steady speed that one tester noted how the Classic “eats the rope back up on recovery.” This smooth agility helps balance out the impact of encountering slow water at the start of every stroke.
The model E’s seat stands 6 inches higher. And while the model D’s monitor rests on an adjustable arm, the E’s sits on unbending metal. These few technical differences do nothing to impact ride feel. We recommend the $200-cheaper model D as the best buy, but the Concept 2 E will appeal to anyone who values a higher seat and more solid construction.
* While there is nothing to adjust from row to row on the WaterRower, it is possible to increase or decrease the level of resistance by changing how much water you put in the drum. The monitor is pre-calibrated to match 17 liters of water, but you can change that if you want. More than 17 liters = more resistance, up to the max fill line. This is not something you'll want to change frequently, it's more of a set-it-and-forget-it thing.

The rowing machine itself is unlike any other on the market with its patented water filled flywheel. It is hard to exactly copy the action of a scull on the water, but the mechanics of the flywheel spinning in water comes in a close second on dry land. The fact that the water is 800 times denser than air means that there is no need for any extra resistance or dampening that you will find in normal air rowers. The faster you pull, the more resistance is generated giving it infinite variability. However, if you want to be able to practice rowing with a faster stroke, you will have to reduce the amount of water in the tank unlike an air rower where you just have to adjust the baffle.

Being able to easily store your rower is a huge plus.

As an example, the Concept2 Model D rowing machine folds up nicely by a simple pull pin located in the middle of the rower. Wheels on the bottom allow for easy moving.
