Bosch Professional GCL 2-50 G Green Combi Laser with RM 10 Mount vs DeWalt DW088K-XJ Self-Levelling Cross Line Laser

Pros

• + Green lines and green plumb points, at a published plus or minus 0.3 mm per metre on the lines
• + IP64 dust and splash protection, the highest ingress rating of the seven
• + Published 50 m working range with the optional LR 7 Professional receiver, for outdoor setting out
• + RM 10 Professional rotating mount, target plate and four AA cells in the box, with a DK 10 ceiling clip available

Cons

• − The LR 7 receiver that unlocks the 50 m range is a separate purchase
• − Bosch Professional's delivery list is a pouch, not a hard case
• − 15 m published visible range is half the green DeWalt cross line at second
• − The most expensive pick on this list

Pros

• + An exceptional Amazon UK rating on the deepest owner record in this category
• + Published plus or minus 3 mm at 10 m, the same as the tools above it costing more
• + Heavy-duty blow-moulded case, mounting bracket and laser target in the box
• + IP54 with a 1 m drop rating, and full-time pulse mode for a DE0892 detector

Cons

• − Red beam: the published working range is 15 m against 30 m for the green twin
• − Washes out in a bright room and outdoors without a detector
• − Cross line only, no plumb points
• − Three AA cells, not a rechargeable pack
