 Equipment used as a singular is a collective noun. We do not inflect collective nouns into the plural for them to take on their collective sense. Nonetheless, equipments also exists as a word, just with a non-collective meaning. Most of the answers you have here are wrong. You have not given an example set of sentences, so there is no way to tell whether you want a singular collective sense or not

Equipment is collective noun and as such can be used in plural. Although there are a lot of collective nouns that can be used with -s or without and they mean different things.

For example what is the plural of water- water. But we can say waters when revering to different types of waters in sea, oceans, river and ect. Another example is folk and folks. Folks is collective noun for group of people, while folks referring to collection of different groups of people.

Therefore when we are speaking about different machines for fitness we can call themequipment. When we are speaking about fitness equipment and fishing equipment, we should useequipments.

Don't forget that English is something alive and in different areas in different countries even native born English folks have their own English within their own community , with different way of living, different jobs, they belong to different parts of the society and ect. English is a languages and there is nothing constant in languages it changes and evolves every day.

Short answer: use 'equipment', do not use 'equipments'

Long answer: in Modern Standard English, 'equipment' is a mass or non-count noun, like 'water' or 'traffic', which describes something that is somehow implicitly plural but doesn't have a plural form. That is, it wouldn't make sense to have more than one equipment, since it describes a set of things already. 'Equipment' is already plural in the sense that it refers to a number of things together. There are instances where one has more than one set of these things, the many waters of the world.
