La Crosse Technology Wireless Pool Thermometer with Indoor LCD — Floating Sensor, 400 ft Range

La Crosse Technology's wireless pool thermometer sends real-time pool temperature readings to a large indoor LCD station so you can monitor current, high and low temperatures from inside your home.

Keep an eye on your pool's water temperature without stepping outside. This kit pairs a floating, battery-powered pool sensor with a 2" indoor LCD display that receives updates from up to 400 ft (121 m) away. The base shows the pool's current temperature, records daily highs and lows, and switches between Fahrenheit and Celsius. The underwater sensor is built to resist water entry with a twist-on battery compartment and has a keyhole for attaching a tether (cord not included) to keep it secure.

How accurate and fast are the temperature readings?

The sensor delivers prompt, stable readings suitable for everyday pool monitoring. While not a laboratory instrument, it gives reliable water temperatures that update to the indoor display quickly over the wireless link.

• Fast response for everyday pool use.
• Displays current temperature and records daily high and low values.
• Switchable °F/°C for user preference.
• Wireless transmission tested up to 400 ft (121.92 m) in open conditions.

How does the pool sensor hold up in water and stay secure?

The floating sensor is designed for pool environments with a sealed twist-on battery compartment to reduce the chance of water ingress. A molded keyhole lets you attach a separate cord or tether to prevent the sensor from drifting away.

• Twist-on battery cover for easier maintenance and better sealing.
• Keyhole attachment point for tether or string (not included).
• Floating design for consistent surface temperature readings.
• Low-battery indicator to warn when sensor power is low.

What features does the indoor display offer?

The compact indoor base station uses a large 2" digital screen and an extra 1" readout for the pool temperature, making figures easy to read from across a room. It stores the day's high and low pool temperatures and alerts you when either the sensor or display batteries are running low.

• Large 2" main digital display for clear viewing at a distance.
• Separate 1" LCD shows the current pool temperature prominently.
• Records daily high and low temperatures for quick reference.
• Low-battery indicators for both sensor and display units.

What power and range considerations should I know?

Both the sensor and the indoor base run on AA alkaline batteries (not included), making setup simple without wiring. The radio link is rated for over 400 ft (121.92 m) in open space; walls and obstacles will reduce effective range, so placement matters.

• Requires 4 AA alkaline batteries total (not included).
• Transmission range over 400 ft in open conditions; indoor range varies.
• Battery indicators help plan replacements before performance drops.
• Quick installation—no wiring or professional setup required.

Who is this for: Ideal for homeowners, pool caretakers, and families who want an easy, reliable way to check pool water temperature from indoors. It’s a practical choice for those who prefer large, readable displays, need daily high/low tracking, and want a floating sensor with a secure tether option. If you want a hardwired or smartphone-connected solution, consider systems with network features; if you want a simple, battery-powered monitor with a clear indoor readout, this La Crosse Technology kit fits that need.
