A Heavy Scyk has 1 shield, 3 hull, and 3 agility. If you plan to Evade/Focus as your action often and avoid getting hit at all, Stealth Device can serve you well. Laetin plays well to this style, but others do fine too. However, once you take even a scratch, Stealth Device is gone.

Pulsed Ray Shield is a point cheaper and favors hit&run tactics, e.g. with Quinn Jast. You spend a turn or two running away, reloading and recharging your shield, and then turn back in for another shot.

And there are other contenders for the mod slot, mainly Guidance Chips.

So it's a matter of playstyle, and what else you're fielding. IMO Stealth Device is a good choice, if you're not running munitions. But I have been trounced by a fleet with 2 or 3 Pulsed Ray Shield Scyks that I couldn't land lasting damage on whatever I tried. I forget what the extra ship was.
