What is the best marine flashlight out there? As you might expect, the answer is subjective. However, there are several things we can agree on:
The best marine flashlight would:
need to be waterproof
have a grip that is non-slip
not be too heavy
have an easy to operate switch
be very bright
have long lasting power and potentially be rechargeable
(Extra feature for spotlights – a collapsable stand for hands-free operations)
Oh, and don’t forget that a marine flashlight needs to serve boaters both day and night! How many times have you had to inspect dark engine compartments, bilges, and under-deck areas in broad daylight?
So what flashlights make the cut?
