I dive on occasion

I dive on occasion and was wanting to work on motivation for improving my health. I completed 2 dives with the watch and it performed great. More importantly it has helped me identify bad habits that was wrecking my sleep quality. I also use it to track fitness activities and it works great for that as well. Happy with the purchase.

Shipping & Delivery

    Right after checkout you receive an email summarizing your purchase, billing & shipping details, and order number. Keep this message handy—it’s your receipt and first reference point.

  • 2. Processing

    Our team verifies payment, allocates stock, and preps the paperwork. If anything stalls (e.g., back‑order), we’ll reach out by phone or email with options.

  • 3. Packing & Labeling

    Products are securely boxed or palletized, then matched with the best carrier: small parcels go UPS/FedEx/USPS; bulky items ride LTL freight. Lead‑time estimates live on every product page.

Yes. Try any product for 30 days. If it isn’t the perfect fit, return it in original condition for a full refund—no restocking fees. (Shipping fees apply only if the return isn’t due to our error or freight damage.)

Are your products covered by a warranty?

Absolutely. Every brand we carry comes with the manufacturer’s warranty—minimum 1 year, often longer on frames and motors. We’re an authorized dealer, so your warranty is 100 % valid. Need help with a claim? Our support team handles all paperwork for you.

Will you price‑match another store?

Yes. If you find an identical item in stock at a lower delivered price, send us the quote or link before you buy and we’ll match it. Our Price‑Match Guarantee protects you for 60 days after purchase as well.

Can I finance my order?
