The Diamond Hand Crimper CH-18 model is the exact crimper we personally use in the shop. It is heavy duty with multiple crimp size options. We prefer this over a bench crimper because it allows you to have a bit more control over the pressure put on each sleeve/crimp to prevent over-crimping and particularly risk damaging the mono connections which will make it more vulnerable to breaking off.
All that being said, these crimping tools will hold up well with a ton of use. Worth the price on this beast.
