Garmin GPS/MAP 540s Question?

[SoCalCJ]

Need a little advise / input?

So I have this Garmin GPS/Map 540s as a backup on my skiff. Is there any reason why this wouldn't work if I installed it on a kayak? Dose anyone have any experience (positive or negative) with this unit? I see RAM makes a rail mount for it that might fit the rail on the PA?

Here's a link to the specs:

Thanks,
