We’ve tested Oversea sensors and most of them can connect to a Hub more than a thousand feet away. The Entry Sensor has a lower range, in the hundreds of feet.
For any single boat or set of boats nearby this range should be perfectly fine. Sensor reach can vary based on where you have your Hub located and where the sensors are located, based on how many walls are between the devices and the composition of the walls.
We urge you to test sensor range on your own. All of our products have a 30-day no questions asked return policy, so in the event you find that your sensor reception isn’t meeting your objectives, we’ll gladly refund your purchase within that window.
