Daily Punch 1-6-20 Shield Grenade weapon for Starfinder

Thinking about something new, and thought about a fun new toy for my players.

Grenade Type	Level	Price	Range	Capacity	Bulk	Special
Grenade, shield I	2	200	20 ft.	Drawn	L	10 feet by five feet hazy wall with 10 hit points
Grenade, shield II	6	700	20 ft.	Drawn	L	10 feet by five feet hazy wall with 20 hit points
Grenade, shield III	10	3,000	20 ft.	Drawn	L	10 feet by five feet hazy wall with 30 hit points

This grenade explodes into a laser wall that springs forth and provides cover and concealment and cover. the wall is 1 inch think and has hit points depending on its level. When you throw the grenade, you choose the direction where the wall will appear. The wall last for one minute or until it takes enough damage to destroy the wall.

Thoughts?
