The Sniper Mine is a weapon manufactured by Gadgetron in Size Matters. It is a sniper rifle in the form of a crossbow which fires an explosive dart that deals more damage the further away it is fired.
The Sniper Mine takes the form of an ancient crossbow, but fires a tachyon-drive self-propelling dart.
The Deadeye Mine is much bulkier and more metallic.
The Sniper Mine is a long distance weapon that deals more damage the further away it is fired. This makes it ideal for firing at targets further away from the player, or for taking out medium to large enemies before entering an area to fight them. As the Sniper Mine must be aimed to be most effective, it is better to fire at enemies not already engaged in combat with Ratchet, or for firing against enemies too large to be missed easily such as bosses.
The Deadeye Mine creates more explosions in the surrounding area after the first one hits, making it more effective at firing against clumps of enemies.
