Customer Reviews

Works exactly as described
Works exactly as described and seems so far to be very durable. Comes with attachments to do many types of engines

A must have product if you are planning to buy a used boat.
I was in the market for a used boat and this thing saved me from a bad decision more than once that week. If you are shopping for a used boat be sure to take one of these with you, it can save you thousands! Remember to do the compression check AFTER a test run when buying. I did find the perfect boat and she runs great with no problems so far. The compression tester works great and looks like it will be around for several years. The pouch could use a separate compartment for the small parts.

Compression Gage
Works great. Has adapters I may not use for a while but nice for when I do. Wish it included a rubber-tipped straight extention for quick checks on 4 valve engines with long reach to the plug holes.
