Nautilus T516 is the big brother of T514 (a review we published on our site a few weeks ago. Find more details HERE).

This treadmill is a training machine dedicated for home use only. Its features are slightly improved than those its little brother has, while the price is almost the same. You can purchase the treadmill with discount at around $1,300 (excluding shipping costs).

For the purpose it has been built (to be a home training machine for regular runners), Nautilus T516 is a good and powerful treadmill. It can easily fulfill its purpose and create an enjoyable training environment.

Nautilus T516 Specifications

On this model you also have preset incline keys and Incline Up/Down arrows. Present values are: 2%, 4%, 6% and 8%.

We found these controls only on the Nautilus models. They are toggle switches on the handlebars available to adjust Speed and Incline. Incline is controlled from the left handle bar and speed from the right one.

T516 has a more powerful motor than its predecessor. This is also a continuous duty motor.

Nautilus T514 Special Features

1. 2 Blue Backlit LCD Display

How to interpret some of the data listed on the LCD display:

Program Display: shows the name of the program you selected. The dot-matrix area shows the course profile for the program. Each column in the profile is an interval (an interval represents 1/12 of the total program time). The flashing column is the current interval.

Total Time: time counted during the workout. Maximum time counted (during a manual workout) is 99:59 minutes.

Distance: counts and shows the distance done during the workout (data is displayed either in km or miles).

Pulse: shows the heart rate in beats per minute (BPM) from the heart rate monitor (HRM).

2. Fan:

The fan is accessible through a button on the console and includes 3 speed levels.

3. Heart Rate readings: through Contact and Chest Strap (telemetry)

The following options are available for both T516 and T514 Nautilus models: Contact Heart Rate (CHR) sensors on the handle bars and a Heart Rate Chest Strap Transmitter. The Console shows your Heart Rate in Beats Per Minute (BPM).

Chest Strap: has attached a heart rate transmitter so your hands are free during workout.

Important note about how to take care of the chest trap:

You must always remove the transmitter before cleaning the chest strap. Cleaning is done with mild soap plus water, and then thoroughly dry it. This must be done on a regular basis because sweat and moisture keep the transmitter active and drain the battery in the transmitter.
