The HX890 floats and is submersible down to 1-1/2 meters for 30 minutes, important features for boating kit. It functions as a standard VHF marine-band two-way radio and can transmit digital distress calls that include latitude and longitude provided by its 66-channel GPS receiver as well as a Maritime Mobile Service Identity (MMSI) number, a unique nine-digit number that is assigned to Digital Selective Calling (DSC) transceivers. We obtained our number through BoatUS; it provides our names, address, emergency contacts and information about our boat. The MMSI number is entered into the HX890 during its initial setup.
Just behind the front roller there are two base plates, one on top, one on the bottom, that make contact with the sanding belt and back it up for working a flat surface. The plates are slightly narrower than the sanding belts, so the belts can work into corners. Closer to the 6307’s body the belt is unsupported, so it will take a gentle curve for working convex contours and softening corners. The front roller has a diameter of 5/8” and can reach into concave surfaces, though it works like a gouge and can’t fair a curve.
The Marlinspike Knife has a hardened 440A stainless-steel 3″ blade with a deep fingernail groove for easy opening. The blade does not lock when open. The frame and pins in the knife are also stainless steel. The blade’s 2-5/8″ cutting edge is straight for its entire length, a very useful feature for cutting line. You can make a long draw cut without having to pivot the knife to keep the whole length of the edge on the rope. The sheepsfoot blade’s flat spine curves down to meet the cutting edge to make a point that reduces the chance of piercing injuries and the blade’s satin finish helps hide fingerprints.
The Explorer 160 delivers that capacity in a 7.5″ x 4.75″ x 6.9″ package that weighs just under 4 lbs. The face of the unit has two ports for 12-volt power, one for charging the Explorer 160 with the included AC adapter or an optional solar panel, the other to supply power to electronic devices using the included cigarette-lighter socket and cord. There are three USB ports, one USB-C and two USB-A. A backlit LCD screen in the middle shows input and output in watts, a graphic of a battery showing the level of charge, and the percent charge remaining. With each device being charged, the display screen shows how many watts are being drawn.
