Why is the River Pool swim spa better than the others?

The Sentry  Pool  was an early pioneer in the swim spa, swim current, lap pool, resistance pool or otherwise endless swimming exercise industry. With many years of development, our swim spa has separated itself from other swim spas by offering a vastly higher quality product, custom built features, and many other benefits that make this world class product what it is today. Our Factory Powder Coated walls will last a lifetime. The quality and structual stength of our pool is by far the best our industry has to offer. We manufacture and engineer our River Pool here in Moline, Il. from the ground up. The strength and quality of our Riverpool will provide you the opportunity for life long swimming and excercise. No body builds it like Sentry, NOBODY!
