This underwater drone revolution is already beginning thanks to a handful of pioneers who are willing to put in the research and development necessary to produce the first deep-diving drones, even if they do look a bit bizarre. One of our top choices is Power Vision PowerRay because not only is it a drone but also a very useful fish finder.

Who it’s for: Divers looking to record the beauty they see under the water

How much will it cost: $3,299.00 pre-order for Oct 2018 delivery

Why we picked the iBubble:

If you’re a diver, then you will love the features of the iBubble underwater drone. It’s allegedly capable of 100 percent autonomy and will follow you around as you swim underwater. Unlike similar submarine UAVs, the iBubble operates without a tether so you can swim freely and not worry about getting tangled up in a cord. You can control it using a bracelet on your wrist.

If you want to stay above the water and explore the area before diving, iBubble does include a tether with a remote control unit and live video through a connected smartphone. There are 8 individually controlled motors and obstacle avoidance technology that helps the UAV swim smoothly down to 200 feet for up to one hour. The iBubble does not include a camera, but you can drop in a compatible GoPro to record your diving footage.

Why should you buy this: The relatively low price tag makes the BIKI an attractive starter model for those looking to experiment with underwater drones

Who it’s for: Early adopters who want to test submersible drones without a huge investment

How much will it cost: $799

Why we picked the:

The Robosea BIKI sets itself apart from its competitors with its unique fish-like design. The drone not only looks like a fish, it actually moves like a fish thanks to a motorized rubber tail fin. Not the fastest drone, the BIKI can glide through the water at a slow 1.12 MPH for up to 90 minutes. The BIKI is one of the few drones which can be controlled wirelessly underwater using a TV-style handheld remote or a smartphone app. Wireless signals don’t penetrate through water very well so you have to immerse the handheld remote and keep it within 33 feet of the drone or use the smartphone app to draw out the path before submerging.

Because of these limitations, the BIKI is best used in shallow waters, even though it can allegedly dive to 60 meters/200 feet deep. BIKI can record video using its 4K, 150-degree field of view video camera, but there is no live view.  The drone has two 114 lumens LED lights and an image stabilization system to improve image quality.

Why we picked the Geneinno Titan:

Geneinno advertises it’s recently launched Titan drone as a professional tool, but the sub-$3,000 price tag is not out of reach for hobbyists who don’t mind paying a bit extra for a high-quality underwater drone. For starters, the Titan has a 9-axis sensor and six thrusters — two horizontal and four vertical — for maneuverability and speed (up to 4.6MPH). An integrated 4K camera with a 160-degree wide angle lens captures both 4K UHD video and 8-megapixel stills. It also delivers a live 1080P video feed to a compatible tablet or smartphone.

For navigation, the Geneinno Titan includes a Nintendo Switch-like controller that fits around a tablet or a phone. The base model ships with a 50M tether cable and a wireless transmitter, though you can upgrade the length of the tether and add other accessories if needed. Expect to get 4 hours of battery life out of a single charge.

4 simple pieces of tech that helped me run my first marathon
Garmin Forerunner 955 Solar displaying pace information.

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.
